1 Safety
1.1 General Potential for Danger
The SSI-BOX cannot function as a stand-alone unit, i.e. it is a component part that is
intended to be installed in a complete system consisting of several such components
working together. This means that the SSI-BOX does not have a direct protection
device of its own.
The user must check the received data from the SSI-BOX for validity.
All the persons who are involved in the assembly, commissioning and operation of the
device
must be appropriately qualified
must follow exactly the instructions in this manual.
This is for your own safety and the safety of your equipment!
1.2 Safety Information
This operating manual contains information that you must comply with to ensure your
personal safety and to avoid damage to property. The information is emphasized by
warning triangles, which have different appearances to match the level of danger:
Warning
Means that if the appropriate safety measures are ignored, death, severe injury or
considerable damage to property can occur.
Caution
Means that if the appropriate safety measures are ignored, slight injury or damage to
property can occur.
Note
Emphasizes important information about the product, its properties or helpful hints for
using it.

1.2.1 Installation information
Due to the fact that the SSI-BOX is normally used as a component part of a larger
system, this information is intended to provide a guideline for safe installation of the
device in its environment.
Warning
Observe the safety and accident prevention regulations that apply to the specific
application.
In the case of equipment with a fixed connection (stationary installations/systems)
without all-pole mains switches and/or fuses, you must install a mains switch or a
fuse in the system and connect the equipment to a protective earth.
Before commissioning devices that are run with mains voltage, check whether the
set rated voltage range matches the local mains voltage.
With a 24-V supply, ensure safe electrical isolation of the extra-low voltage. Use
only mains units that comply with IEC 364-4-41 or HD 384.04.41 (VDE 0100 Part
410) standards.
Fluctuations in or deviations from the rated mains voltage may not exceed the
tolerances stated in the technical data. If they do, functional failures of the electrical
components and hazardous conditions cannot be ruled out.
You must take precautions to ensure that, following voltage dips and failures, it is
possible to restart an interrupted program in an orderly manner. In this context, no
dangerous operating status conditions may occur even for a brief period of time. If
necessary, you must force an EMERGENCY STOP.
EMERGENCY STOP devices that comply with EN 60204/IEC 204 (VDE 0113)
must remain effective in all the operating modes of the automation equipment.
Unlocking the EMERGENCY STOP devices must not result in an uncontrolled or
undefined restart.
Install the connecting and signal lines such that inductive and capacitive
interference does not adversely affect the automation functions.
Install automation technology equipment and its operator input elements such that
they are sufficiently protected against being operated by mistake.
Take appropriate hardware and software measures in the I/O link to prevent
possible cable or wire breakages on the signal side leading to undefined status
conditions in the automation equipment.

1.2.1.1 Wiring the converter housing
Note
In addition to the connection terminals, the converter housing contains all the
electronics for converting SSI signals that come from the encoder into appropriate
Profibus data. To protect the electronics from environmental influences, we chose a
housing that complies with type of protection IP 67 according to DIN 40 050.
Please be sure that during cabling you use the proper cable screw glands and their
seals (o-rings). The lid of the housing must be tightened correctly (see "Appropriate
Use" on page 10). Screw glands and lid must be sealed properly. If dirt or oil will
penetrate inside the converter housing the electronic will be damaged.
Connection You should use the Siemens-specified twisted-pair cables for the positive and
negative signals of the SSI clock, SSI data and RS485 signals.
For the Profibus, you only need to connect the DataA and DataB terminals. On the
connection board, there are two sets for the lines to the previous station and to the
next one. Terminals P5V2 and M5V2 must be kept open.
Chapters 4 and 5 of the manual entitled Distributed Peripheral System ET200 contain
supplementary information about additional line lengths and installation of the
Profibus. You can obtain this manual from Siemens quoting order number
EWA 4NEB 780 6000-01

1.2.1.2 Connecting the Cable Screening to the Converter Housing
To prevent disturbance signals entering the converter housing, we used cable screw
glands with which it is possible to connect the screen on the inside. For this reason, no
connection point for the screen is provided inside the converter housing.
Procedure:
1. Screw the cable screw gland into the housing.
2. Dismount the compression nut (1) and the terminal holder (2).
3. Push the compression nut (1) and the terminal holder (2) over the cable.
4. Strip the cable; push back the braiding around the terminal holder (2) such that the
braiding goes over the inner O-ring (3) and does not lie over the cylindrical section
or the torsional bars.
5. Insert the terminal holder (2) into the intermediate gland (4) such that the torsional
bars fit into the intended lengthwise grooves in the intermediate gland (4).
6. Screw the compression nut (1) to the intermediate gland (4).

3 Characteristics of the SSI-BOX / Commissioning
Note
An encoder exchange only do when the voltage is switched off.
3.1 SSI-BOX PNO identification number
The SSI-BOX has the PNO ID number AAAB (hex). This number is reserved and filed
with the PNO.
3.2 Type file / device master file
The type files used with the SSI-BOX have the filename "TRSS00XX.200" and the
device master file which is used has the filename " TR09_SSI.GSD".
3.3 Start-up on PROFIBUS
When started up, the SSI-BOX has the status 'Baud search'. After detecting the Baud
rate, it switches to the status WAIT_PRM and waits for the parameterization data from
the DP master. Parameterization takes place automatically during the start-up phase
of the DP master. The parameters transferred to the SSI-BOX are the code
sequence, the measuring length in increments and the number of increments per
revolution (see PNO encoder profile for more details). After a successful
transmission of formally correct parameterization data, the SSI-BOX switches to the
status WAIT_CFG. The PROFIBUS master then sends a configuration byte in order to
define the number of inputs and outputs. If the configuration byte is correct, the SSI-
BOX switches to the status DATA_EX.

3.6 Configuration and parameterization
Parameterization, i.e. the transfer of parameters for the code sequence, encoder
resolution, etc., exclusive takes place within the configuration program for the relevant
PROFIBUS master (a programming via "EPROG"-program is not possible). For this
purpose, the type file of the SSI-BOX must be copied into the relevant directory for
type files. In the case of some programs, such as COM PROFIBUS or STEP7
Manager, the internal equipment list (hardware catalogue) has to be updated within
the software. For more information on the integration of field devices, please refer to
the documentation supplied with your software.
In order to integrate and parameterize the SSI-BOX in a master system, it is usually
necessary to carry out the following two steps within the configuration program.
3.6.1 Configuration
For configuration purposes, i.e. input of length and I/O type on the PROFIBUS, the
configuration program usually provides an input mask in which the identifier is
normally preset depending on the nominal configuration, so that all you have to do is
enter the I/A addresses.
Depending on the required nominal configuration, the SSI-BOX will assign a
different number of input and output words on the PROFIBUS.
The parameters described below are also dependent on the nominal configuration.
In the following, the individual nominal configurations are described, together with the
position of the communication bytes for data exchanges with the PROFIBUS-DP
master.
