DATE 12/17/99 PAGE 1 of 3
SUBJECT: Manufacturing Discontinuation Notice for
SIMATIC Series 500 and 5TI/6MT Product Families
The SIMATIC Series 500 Product Family has had a long and successful life. Born in the early
1980's, the Series 500 Product Family was matured in the late 1980’s and is still being manufactured
10 years later in order to meet our customers needs. Siemens recognizes the need for this long-term
commitment for the products it provides for the industrial marketplace. Siemens also recognizes the
need to keep customers aware of the status of its older product lines.
Therefore, in keeping with the terms of the Classification Change Notice of October 1996 for
these products, Siemens Energy & Automation, Inc. is announcing the Discontinuation of
Manufacture of the SIMATIC Series 500 and 6MT Product Families as follows:
Family Date of last Manufacture Begin "Service Only" Minimum Repair Service
6MT Products June 2000 December 2000 December 2003
Series 500 Family December 2000 December 2001 December 2003
.This early notification is being given in order to give our customers ample opportunity to
purchase adequate spares or make other adjustments in order to sustain their process for the
duration. This move is necessitated by the fast moving nature of the electronics industry with its
relentless elimination of older electronic component parts, combined with a substantial decline in
customer demand for these products, making continued production impractical. Fortunately, the
SIMATIC 505 line as the successor product line provides a viable alternative solution in most cases.
The SIMATIC Series 505 Product Family, the next generation to the Series 500, was
developed to simplify the automation control task and give our customers a competitive edge with
state-of-the-art performance at an affordable price. The transition of our customers from the Series
500 to Simatic 505 has been highly successful due to high compatibility and easy transferability of
the user programs via Tisoft or SoftShopfor Windows, as well as universal I/O connectivity.
In addition, the new Series 500 PROFIBUS-DP RBC has been designed to preserve our
customer's investment in Series 500 I/O and associated field wiring by allowing easy re-connection of
Series 500 I/O bases to all Siemens PLC lines now and into the future via PROFIBUS-DP.

The following points will be of interest to our Series 500 customers:
1. Siemens will take new orders for the Series 500 and 6MT products listed on the attachment up
until the "Service Only" date as long as stocks are available. These orders are subject to
standard customer service policies.
2. For this announcement, the list price and terms will remain as stated on the latest price list.
However, these prices are subject to change due to future market conditions.
3. Product lead-times may vary, but all effort will be made to satisfy customer demands.
4. Siemens Energy & Automation, Inc. Standard Policy for phased-out product: Siemens
Energy & Automation, Inc. remains committed to provide at least seven years of service and
support for those SIMATIC products transferred from Texas Instruments, Inc., including upgrades
and additions to that product line made by Siemens. The seven-year support period for the Series
500 and 6MT product families began with the effective announcement in October 1996. However,
Siemens will continue to provide repair services on these products for as long as practical beyond
the seven-year period, just as is being done today with many other obsolete products.
5. The following products are exempted from this announcement and will be sustained for 5 years or
so in order to assist customers in connecting their existing Series 500 I/O bases to newer Siemens
PLC systems via PROFIBUS-DP when desired:

Setting the CPU Dipswitches (continued)
The 545 and 555 CPUs have two communications ports. Both ports are
configured as Data T erminal Equipment (DTE).
SW2 selects Port 1 as either a programming port or a printer port on a
545/555 CPU. Port 1 uses an RS-232/RS-423 signaling protocol and an
RS-232 pinout arrangement with an RS-423 (+5 V) signal level extending
up to 50 feet (15 m). Y
ou can use a modem to extend this distance.
• Setting SW2 to the left selects Port 1 as a programming port.
• Setting SW2 to the right selects Port 1 as a printer port.
Figure 3-13 shows the locations of Port 1 and Port 2 on the front of the CPU.

Figure 3-13 545/555 CPU Port Locations
W ith the 545 and 555 CPUs, your choice of cabling determines whether
Port 2 functions as an RS-232/RS-423 port or as an RS-422/RS-485 port.
Figure 3-13 describes the pinouts required for the various Port 2 options.
If you use RS-422/RS-485 cabling, SW1 on the dipswitch allows you to select
between RS-422 and RS-485. Use SW1 as follows:
• Set SW1 to the left when you use RS-232 or RS-422 cabling.
• Set SW1 to to the right when you use RS-485 cabling. RS-485 uses a
single twisted pair to transmit and receive data between the
programming device and the 545/555 CPU. Multiple CPUs or multiple
programming devices (on this RS-485 link) are not supported and must
not be used.

SIMATIC 545/555/575 System Manual Installing 505 System Hardware
For Communication Port 2, the maximum permissible cable length depends
on the type of connection used:
• The RS-232/RS-423 connection can extend a maximum of 50 feet
(15 m).
• The RS-422/RS-485 connection can extend a maximum of 3300 feet
(1 km).
The cable installation for RS-485 or RS-422 can include a 120-ohm
termination resistor across the signal conductors at each end of the cable.
The resistor provides a higher noise immunity and better long-distance
communication.
The 545–1 104/–1 106 and 555 CPUs have two remote I/O ports.
• The I/O port is a 9-pin female port used to communicate directly with
Series 505 RBCs by means of a shielded, twisted-pair RS-485 cable.
• The PROFIBUS-DP port is a 9-pin female port used to communicate to
a variety of PROFIBUS-DP slaves and field devices in daisy-chain
fashion across a shielded, twisted-pair RS-485 cable that meets
PROFIBUS standards.
The 545–1 103 CPU has the option of a PROFIBUS-DP port if you install the
PPX:505–CP5434–DP annex card.

1 Introduction
The PROFIBUS OLM (Optical Link Module) product family consists of
OLM/P11,
OLM/P12,
OLM/G11,
OLM/G12,
OLM/G12-EEC,
OLM/G11-1300 and
OLM/G12-1300.
PROFIBUS OLMs are designed to be used in optical PROFIBUS field bus networks. They enable electrical PROFIBUS
interfaces (RS 485 level) to be converted into optical PROFIBUS interfaces and vice-versa.
By profiting from the familiar advantages of optical transmission technology, the modules can be integrated into
existing PROFIBUS field bus networks. A complete PROFIBUS field bus network with modules in line, star or ring
topology, and an arbitrary combination of these, can also be built up.
The redundant ring is also supported, thereby increasing the fail-safety of the field bus network.
Each module has two or three mutually independent ports, which in turn consist of a transmitting and a receiving
component.
The device is powered by 24VDC voltage. A redundant feed increases operational safety.
The electric port is a 9-pole Sub-D socket (female). An RS 485 bus segment in line with the PROFIBUS standard
EN 50170 can be connected to this port.
The optical fibers are connected using BFOC1) /2.5 connectors.
Four multicolored light-emitting diodes indicate the current operating status and possible operating malfunctions.

PCF stands for Polymer Cladded Fiber, and is the same as HCS ®. HCS is a registered trademark of Ensign-Bickford
Optics Company.
One measuring output is available for each optical port where the optical input level can be measured using a
conventional voltmeter.
Different OLM malfunction reports are provided as an accumulative signal via a signaling contact (relay with
unconnected contacts) for further processing.
The mechanical design consists of a compact, stable metal housing which can be mounted on a DIN rail or mounting
plate as required.
The module is configured using easily accessible switches.
The PROFIBUS OLM complies with the standard EN 50170 and the technical guidelines issued by the PROFIBUS
user organization, PNO, ”PROFIBUS optical transmission technology“.
OLM/G12 und OLM/G12-EEC have the same function. They only differ in the specification of the climatic ambient
conditions: while the OLM/G12 is suitable for employment in the standard temperature range from 0°C to 60°C,
the OLM/G12-EEC (extended environmental conditions) can be used in the extended temperature range from
–20°C to +60°C and at up to 100% humidity.

2 General Functions
Version 2.1 10/01
2 General Functions
Transmission rate
The PROFIBUS OLMs support all the transmission speeds (transmission rates) defined in the EN 50170 standard:
9.6 kBit/s, 19.2 kBit/s, 45.45 kBit/s, 93.75 kBit/s, 187.5 kBit/s and 500 kBit/s,
and additionally
1.5 MBit/s, 3 MBit/s, 6 MBit/s and 12 MBit/s.
The transmission rate is set automatically as soon as the PROFIBUS OLM receives a frame. The setting or adjust-
ment is dependent on the transmission rate and the set operating mode. Depending on the OLM, this can last up to
several seconds.
If the transmission speed has not been recognized, the outputs of all ports are blocked. If the transmission rate
changes during operation, this is detected by the modules, which then automatically adjust their settings accordingly.
Transfer malfunctions may temporarily occur while the rate is being altered.
Signal regeneration
The modules regenerate the signal form and amplitude of the data received. This allows up to 122 PROFIBUS OLMs
to be cascaded (limited by the address space in PROFIBUS networks).
Help when setting up
At least one bus subscriber must be switched on and active in order to check the optical fiber connections during the
installation. This bus subscriber serves as the frame source. The PROFIBUS OLMs act passively when it is switched
on. They recognize the transfer speed from the frames sent by the bus subscriber. An optical help when putting the
device into operation is provided by the port LED which then lights up.
The operating mode is set using switches located on the top of the module. A sticker attached to the side of the
module provides assistance with the settings.
Segment monitoring at the RS 485 port
If the operating mode ”Electric port with segment monitoring“is set, each receiver monitors the RS 485 bus segment
connected to it for faulty frames or continuously busy networks. If faulty frames are received by the receiver, or if the
network is busy for longer than the maximum permitted send time, forwarding of the received signals is blocked until
frames can be received again correctly, or if no signal is received for one second.
The RS 485 bus segment is not monitored in the operating mode ”Electric port without segment monitoring“.
Interference from the electrical segment affects the entire network.
Please observe the installation notes in 4.4.4. ”Connecting the electrical RS 485 bus lines“, p. 24 .

2 General Functions 2.2 Operating mode related functions
8Version 2.1 10/01
The following functions are only available for the optical ports. Whether the functions can be activated depends on
the operating mode which has been set. Please refer to the following chapters for details.
Line monitoring with echoes
The modules enable the connected optical paths to be actively monitored for interruptions in the fiber line by means
of the functions ”Send echo“, ”Monitor echo“and ”Suppress echo“.
Send echo
A frame which is received by a module via any port is transmitted to all other ports. If the receiving port is an optical
port, the module sends the frame back to the corresponding optical sender.
Monitor echo
If a module sends a frame - no echo! –to an optical port, the module expects to receive an echo. If the echo is not
received after a predefined time, an echo monitoring error is indicated by a red LED belonging to the port.
Suppress echo
The relevant receiver is separated from the other ports from the moment a frame is sent until the echo has been
received correctly.
Segmentation
If an echo monitoring error or a frame falsification arises at an optical port, the module assumes that the line is faulty
and blocks this port for user data. The connected field bus partial network is then segmented (cut off). This segmen-
tation causes the module at the other end of the optical fiber to be segmented as well.
Both modules connected to the segmented field bus partial network send test frames to the segmented ports. These
test frames –which are to be received regularly –can be used by both modules to check the status of the field bus
partial network.
The segmentation is automatically lifted as soon as the test frames indicate to both modules that the segmented field
bus partial network is no longer disturbed.
If all active bus subscribers are deactivated in a previously active network, the modules are segmented cyclically in
order to check the fiber links to the neighboring modules. If there is no frame traffic, but the fiber links are intact,
the port LEDs of the optical ports flash yellow cyclically.

3 Network Topologies
The following network topologies can be realized with the PROFIBUS OLM:
Point-to-point connections
Line topologies
Star topologies
Redundant optical rings
Combinations of these basic types are also possible. Lines with two optical fibers are used to create the fiber links for
these network topologies.
If a malfunction –e.g. a break in a fiber line –makes a high degree of field bus network fail-safety necessary, the
availability of the network can be increased using a redundant network configuration.
Please note:
Single terminals or entire PROFIBUS segments with max. 31 subscribers can be connected to the electrical
interface of the PROFIBUS OLM.
In areas with a high EMC incidence, only lay optical fiber lines in order to exclude the possibility of EMC
affecting the whole network.
Optically only OLMs of the same type can be connected together:
–OLM/P11 with OLM/P12
–OLM/G11 with OLM/G12 and OLM/G12 EEC
–OLM/G11-1300 with OLM/G12-1300
Optical ports which are connected by optical fiber must be set to the same operating mode.
Junctions between different OLM types are only possible via the RS485 interface.
OLM/G12-EEC can be used everywhere in those network topologies described below in which a OLM/G12 can
also be used.

3 Network Topologies 3.1 Line topology
10 Version 2.1 10/01
In a line structure, the individual PROFIBUS OLMs are connected together by dual-fiber optical fibers. Modules with
one optical port are sufficient at the beginning and end of a line, between which modules with two optical ports are
necessary.
If single point-to-point connections are to be built up, this can be achieved using two modules each with one optical
port.
The line topology can be realized with and without fiber link monitoring. If both operating modes are used within
an optical fiber line, the operating mode ”Line topology without fiber link monitoring“determines the availability of
this fiber line. It is recommended that fiber link monitoring be used in homogeneous OLM networks (default factory
setting).
Please note that the following ambient conditions must be fulfilled to ensure that network configuration functions
correctly:
The parameters MIN TSDR described in the PROFIBUS standard EN 50170 must be set to a value ≥11 on
all terminals. This is usually the case, but the setting should be checked if communication malfunctions
continuously arise.
When configuring your network, select low bus subscriber addresses wherever possible. This ensures that
master timeout times which may arise are kept as short as possible in the event of a malfunction.
Refer to the manufacturer’s manual of the terminal concerned for details about how to alter the settings.
3.1.1 Line topology with optical fiber link monitoring and segmentation
This operating mode should preferably be used if an interrupted fiber segment is to be separated from the rest of the
network.
Only use this operating mode if you have just connected PROFIBUS OLMs together of the same version.
Monitoring mechanisms:
Send echo: yes
Monitor echo: yes
Suppress echo: yes
Monitor: yes
Segmentation: yes
In this operating mode the individual fiber links are monitored by the two connected modules.
If a module fails, an optical fiber breaks or faults are determined on the optical transfer link, the fiber link between the
two OLMs is interrupted (segmented). The PROFIBUS network is divided into two partial networks, which remain
functional independently of one other.
The malfunction is indicated at the two OLMs connected to the malfunctioning fiber link by the port LEDs switching
to red and by activation of the signaling contacts. The segmentation is lifted automatically as soon as both modules
recognize that the field bus network is functioning correctly with the help of test frames.
Please note that in the case of networks with several active bus subscribers, two logical token rings are formed in the
event of an error. Every time the partial networks are switched together, network malfunctions may arise due to the
double tokens or frame collisions.
Note:
If a module with two optical ports is used at the beginning or end of a line, the optical port which is not assigned
must be switched to the operating mode ”Line without fiber link monitoring“, so that it does not signal a break in the
fiber line.
Please note that optical ports which are not connected must always be fitted with protective caps to guard against
extraneous light and dirt.

Electrical star segment
S0 = 1 S0 = 1 S0 = 1 S0 = 1 RS 485 bus line
Optical fiber
Several modules are combined to form an active PROFIBUS star coupler. Other modules are connected to this by
dual-fiber optical fiber lines. The modules of the star coupler are connected to one another via the electrical port
(electrical star segment).
All OLM types for different fiber types (plastic, PCF, glass) can be combined using the electrical star segment.
Please note:
CH1 in mode ”Monitor off“(S0 = 1) must be activated on all OLMs which are connected to the electrical star
segment. This deactivates the segmenting function of the RS 485 port on these OLMs, providing a high degree
of availability of the electrical star segment.
Ensure that the electrical star segment is wired carefully. Keep it as small as possible to avoid interference
injection into the electrical star segment, and from here into the entire network. This can be achieved by laying
out the OLMs in the electrical star segment directly next to each other on a DIN rail.

3.3 Redundant optical ring
Switch on the terminating resistors in the bus port connectors (see 4.4.4, ”Connecting the electric RS 485 bus
lines“, p. 24) at both ends of the electrical star segment.
Do not connect a bus subscriber to the electrical star segment wherever possible.
Modules with one or two optical ports can be used to create an active PROFIBUS star coupler. Modules with one
optical port are sufficient for connecting a terminal or an RS 485 bus segment to the active star coupler.
If the link monitoring on the optical ports is activated, the fiber optic links are monitored by the respectively connected
OLM.
Note:
Optical ports which are not assigned (for instance, because they are reserved for a future system extension) indicate
a fiber break if the link monitoring is activated.
You can prevent this error report from being issued by activating the operating mode ”Line without fiber link monito-
ring “at the non-assigned ports.
Please note that optical ports which are not connected must always be fitted with protective caps to guard against
extraneous light and dirt.
