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 displayed in the following figure.

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.
