WARNING!
Removal/Insertion under power
The devices are not designed for removal or insertion under power. Because of
unforeseeable consequences, it is not allowed to plug or unplug devices with
the power being ON.
Make sure that all voltage sources (supply and process voltage) are switched
off before you
– connect or disconnect any signal or terminal block
– remove, mount or replace a module.
Disconnecting any powered devices while energized in a hazardous location
could result in an electric arc, which could create a flammable ignition resulting
in fire or explosion.
Make sure that power is removed and that the area has been thoroughly
checked to ensure that flammable materials are not present prior to proceeding.
The devices must not be opened when in operation. The same applies to the
network interfaces.
For information on mounting and demounting, please refer to the chapter
mounting and demounting the communication modules

Chapter 2.6.3.5
“Mounting/Demounting the communication modules” on page 987.
The communication between the processor module and the communication modules takes
place via the communication module bus, which is integrated in the terminal base. Depending
on the used terminal base up to 6 communication modules can be connected.

Chapter 1.2.1 “TB56xx for AC500 V3 products” on page 4
There are no restrictions concerning which communication modules can be arranged for a
processor module.
Within the AC500 control system, the communication modules can be used as
● bus master or
● slave.
It depends on the
● selected protocol,
● the functionality of the communication module and
● the several field buses and networks.
The following name extensions of the device names describe the supported field bus/protocol:
● CMxyz-ETH: Ethernet
● CMxyz-DP: PROFIBUS
● CMxyz-PNIO: PROFINET
● CMxyz-ETHCAT: EtherCAT
● CMxyz-CN: CANopen
● CMxyz-RCOM: RCOM/RCOM+ protocol (and 2 serial interfaces)
● CMxyz-RS: 2 serial interfaces (COM1/COM2)
If a XC version of the device is available, for use in extreme ambient conditions (e.g. wider
temperature and humidity range), this is indicated with a snowflake sign.
