1.1.1.2 Connections
1.1.1.2.1 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 assembly chapter Ä Chapter 2.4.1 “Serial
I/O Bus” on page 1178).
1.1.1.2.2 Power Supply
The supply voltage of 24 VDC 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 con-
ductor) via these terminals.

NOTICE!
Risk of damaging the processor module and terminal base!
Exceeding the maximum voltage could lead to unrecoverable damage to the
system.
The system could be destroyed.
NOTICE!
Risk of malfunction!
To ensure reliability and proper functionality, 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 con-
nected (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).
1.1.1.2.3 Serial Interfaces COM1/COM2
The serial interface COM1 is connected to a removable 9-pin terminal block. It is configurable
for RS-232 and RS-485 and can be used (depending on the processor module) for:
● Online access (RS-232 programming interface for Automation Builder)
● A free protocol
● Modbus RTU, client and server
● CS31 system bus (RS-485), as master only Ä Chapter 2.6.4.8.2 “Wiring” on page 1283

CAUTION!
Risk of damaging the PLC modules!
The PLC modules must not be removed while the plant is connected to a power
supply.
Make sure that all voltage sources (supply and process voltage) are switched
off before you remove or replace a module.
Analog signals must be transmitted through shielded cables. The analog cable
shield must only be connected to the side of the module (SH terminals) to avoid
relaxation currents influencing the measuring results and for optimal robustness
against external noise. The shield connection must be as short as possible (< 3
cm). The analog shield is capacitive and internally coupled with the functional
earth (FE). To avoid unacceptable potential differences between different parts
of the installation, low-resistance equipotential bonding conductors must be laid.
CAUTION!
Risk of damaging the processor module and terminal base!
Voltages surpassing the permitted range might damage the processor module
and terminal base.
Never connect supply and process voltages > 30 VDC to the terminal base.

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 con-
nected (e. g. +/- of power supply is connected to both L+/L+ or both M/M)
NOTICE!
Risk of damaging terminal base!
Excessive current might damage the clamp and terminal base.
Make sure that the current flowing through the spring terminals never exceeds
10 A.

1.2 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 uninterrupted output. All I/O
modules can be freely connected in a simple, stable and reliable manner.
