Depending on the device type, various operating elements provided on the front panel can be
used to control the devices of the PLC system and/or to change the operating mode.
Operating elements:
● Status LEDs:
Indicates the availability of devices/components such as communication modules, commu-
nication interface modules or function modules. Functionality and diagnosis of the status
LEDs depends on the specific module and is described in the device description of the
appropriate module. Possible status: on/off/blinking
● I/O LEDs:
Displays the status of the the inputs and outputs.
● LED display:
Available for some processor modules. It can be used for simple configurations and for
reading out diagnosis information.

1.2.1.2 Connections
1.2.1.2.1 I/O bus
The I/O bus is the I/O data bus for the I/O modules. Through this bus, I/O and diagnosis data
are transferred between the processor module and the I/O modules. Up to 10 I/O modules can
be added (see description for I/O bus in the system asembly chapter Ä Chapter 2.4.1 “Serial I/O
bus” on page 911).
1.2.1.2.2 Power supply
The supply voltage of 24 V DC is connected to a removable 5-pin terminal block. L+/M exist
twice. It is therefore possible to feed e.g. external sensors (up to 8 A max. with 1.5 mm2
conductor) via these terminals, when the ambient temperature never exceeds 60 °C.

NOTICE!
Risk of damaging the processor module and terminal base!
Exceeding the maximum voltage could lead to unrecoverable damage to the
system.
The system might be destroyed.
NOTICE!
Risk of malfunction!
To ensure reliability and proper functionality of processor modules below index
C0, the supply voltage must ramp-up from 0 V to 24 V within max. 2.5 s.
NOTICE!
Risk of damaging the terminal base and power supply!
Short circuits might damage the terminal base and power supply.
Make sure that the four clamps L+ and M (two of each) are not wrongly
connected (e. g. +/- of power supply is connected to both L+/L+ or both M/M).

NOTICE!
Risk of damaging the terminal base!
Terminal base can be damaged by connecting the power supply terminal block
(L+/M) to COM1.
Make sure that the COM1 terminal block is always connected to the terminal
base even if you do not use COM1 to prevent this.
NOTICE!
Risk of damaging the terminal base!
Excessive current might damage the clamp and terminal base.
Make sure that the current flowing through the removable clamps never
exceeds 8 A (with 1.5 mm2 conductor).
NOTICE!
For applications using XC versions!
To ensure reliability and proper function, make sure the ambient temperature
never exceeds 60 °C when the current flowing through the removable clamps is
8 A (with 1.5 mm2 conductor).
1.2.1.2.3 Serial interface COM1
The serial interface COM1 is connected to a removable 9-pin terminal block.
From firmware version V3.1 it is configurable for RS-232 or RS-485 (V3.0 RS-232 only).

1.2.1.2.4 Ethernet interface
This interface is the connection to a processor module with onboard Ethernet e.g.
PM56xx-2ETH.
TB56xx-2ETH for processor modules PM56xx-2ETH provide 2 independent
Ethernet interfaces.
The two Ethernet interfaces can be configured as independent interfaces or with
switch functionality.
In case of two independent interfaces they must be configured to different
subnets.
For structured Ethernet cabling only use cables according to TIA/EIA-568-A,
ISO/IEC 11801 or EN 50173.

The maximum possible bus length of a CAN network depends on bit rate (transmission rate)
and cable type. The sum of all bus segments must not exceed the maximum bus length
Bit Rate (speed) Bus Length
1 Mbit/s 40 m
800 kbit/s 50 m
500 kbit/s 100 m
250 kbit/s 250 m
125 kbit/s 500 m
50 kbit/s 1000 m
Only bus cables with characteristics as recommended in ISO 11898 are to be used. The
requirements for the bus cables depend on the length of the bus segment. See
Ä Chapter
2.6.4.6 “CANopen field bus” on page 995.
Both ends of the CAN bus have to be terminated with a 120 Ω (≥ 1/4 W, ≤ 5 %) bus terminating
resistor, to minimize signal reflection. The bus terminating resistor should be connected directly
at the bus connector between the CAN signals (CAN_H and CAN_L). See
Ä Chapter 2.6.4.6
“CANopen field bus” on page 995.
1.2.1.3 Technical data
The system data of AC500 and S500 are applicable to the standard version. Ä Chapter 2.6.1

1.3 Processor modules
The AC500 product family consists of the product groups:
● AC500 (standard):
AC500 standard PLCs offer a wide range of performance levels and scalability. The PLCs
are highly capable of communication and extension for flexible application.
● AC500-eCo:
AC500-eCo PLCs are cost-effective, high-performance compact PLCs that offer total inter-
operability with the core AC500 range and provide battery-free data buffering. All I/O
modules can be freely connected in a simple, stable and reliable manner.
● AC500-S:
AC500-S PLCs are designed for safety applications involved in factory, process or machi-
nery automation area.
● AC500-XC:
AC500 (standard) and AC500-S provide devices with -XC extension as a product variant.
These variants operate according to their product group and can, in addition, be operated
under extreme conditions. AC500-XC PLCs can be used at high altitudes, extended oper-
ating temperature and in humid condition. Further, the devices provide immunity to vibration
and hazardous gases. The AC500-XC series is consistent with standard devices in the
overall dimensions, control function and software compatibility. Ä Chapter 2.7.1 “System
data AC500-XC” on page 1023.
The AC500 product family is characterized by functional modularity. As the complete AC500
product family shares the same hardware platform and programming software tool, the devices
of the AC500 product groups can be flexibly combined.
S500 devices represent the I/O modules of the product group AC500 (standard), whereas
S500-eCo devices represent the I/O modules of the product group AC500-eCo. Both S500 and
S500-eCo devices can be combined with devices of the AC500 product family in a flexible way.

The PM50x2 processor modules are supplied with option board slot covers as
standard.
There are various TA51xx option boards for the processor modules that can be
ordered separately.
Which and how many option boards can be plugged, depends on the respective

● I/O bus (not for PM5012-x-ETH)
● Real-time clock (PM5012-x-ETH needs additional RTC option board)
● Option board slots for extension on the CPU (1 for PM5012-x-ETH, 2 for PM5032-x-ETH, 3
for PM5052-x-ETH and PM5072-T-2ETH)
● 6 digital inputs (PM5012-x-ETH), 12 digital inputs (PM5032-x-ETH, PM5052-x-ETH,
PM5072-T-2ETH)
● 4 transistor outputs (PM5012-T-ETH), 8 transistor outputs (PM5032-T-ETH, PM5052-T-ETH,
PM5072-T-2ETH)
● 4 relay outputs (PM5012-R-ETH), 6 relay outputs (PM5032-R-ETH, PM5052-R-ETH)
● 2 configurable digital inputs/outputs (not for PM5012-x-ETH)
The various processor module variants differ in the following characteristics:
● Type of the digital outputs (transistor or relays)
● Ethernet interface one or two independent interfaces
All processor module variants include a micro memory card slot.

1.3.1.1.3 Connections and interfaces
The I/O bus is not available for PM5012-T-ETH and PM5012-R-ETH. I/O
channel extension using option board slot only.
The I/O bus is the I/O data bus for the I/O modules. Through this bus, I/O and diagnosis data
are transferred between the processor module and the I/O modules. Up to 10 I/O modules for
PM5032-x-ETH (but with a limit of 128 Bytes input/ 128 Bytes output variables) and 10 I/O
modules for PM5052-x-ETH and PM5072-T-2ETH can be added.

Depending on the processor module variants, an additional option board can be connected to
the option board slot to extend the feature of the processor module .
RS-232 communication interface is available by using option board:
● TA5141-RS232I (isolated)
Ä Chapter 1.3.1.2.6 “TA5141-RS232I - Option board for COMx serial communication”
on page 75
RS-485 communication interface is available by using option boards:
● TA5142-RS485I (isolated)
Ä Chapter 1.3.1.2.7 “TA5142-RS485I - Option board for COMx serial communication”
on page 78
● TA5142-RS485 (non isolated)
Ä Chapter 1.3.1.2.8 “TA5142-RS485 - Option board for COMx serial communication”

CAUTION!
Risk of damaging the AC500-eCo V3 processor module and the connected
modules!
Voltages > 30 V DC might damage the processor module and the connected
modules.
Make sure that the supply voltage never exceeds 30 V DC.
1.3.1.1.5 State LEDs and operating elements
The processor modules, PM50xx series, have a RUN/STOP button. By pressing the RUN/STOP
button, the processer modules switch between RUN mode and STOP mode. By long-pressing
RUN/STOP button during the processor module power on phase, the processor module will be
in MOD1.
The processor modules PM50xx indicate their states of operation via 5 LEDs located on the
upper left side of the processor module.
