1.7 Communications Modules
Communications modules provide additional flexibility for VersaMax systems.
These communications modules install on a VersaMax Communications Carrier. Power
for the communications module comes from the main system power supply or from a
booster supply as shown below.

1.7.1 Available VersaMax PLC Communications
Modules
The following VersaMax PLC communications modules are available:
Communications Modules
Profibus-DP Network Slave Module IC200BEM002
DeviceNet Network Control Module IC200BEM103
Asi Network Master Module IC200BEM104
Serial Communications Module IC200CMM020
Communications Carrier IC200CHS006
For information about the Communications Carrier, refer to the VersaMax Modules,
Power Supplies, and Carriers User Manual (GFK- 1504).
1.7.2 Profibus-DP Network Slave Module
The Profibus-DP Network Slave Module (IC200BEM002) is a communications module
that exchanges PLC reference table data on the Profibus network. The VersaMax PLC
CPU can read and write this data as though it were conventional bit- and word-type I/O
data.
Multiple Profibus-DP Network Slave Modules may be used in the same VersaMax PLC.
Each one can read up to 244 bytes of data from the network, and send up to 244 bytes of
output data. The total amount of combined inputs and outputs is 384 bytes.
For information about the Profibus-DP Network Slave Module, refer to the VersaMax
System Profibus Network Modules User Manual
(GFK-1534, revision A or later).
