The SCM Step and push FB are the only block types that can initiate peer push/store requests for CEE to CEE peer
communications. The number of parameters communicated per second depends upon target device configuration and use of
requested Function Block
2
The communication performance depends upon the response from the target device, the number of Exchange FBs
communication through the same path and the application implementation in the target device.
Peer-to-peer communication between a
Controller
and
PLC’s
or other
devices
is also supported. The
Exchange
FBs
support both the PCCC (Programmable Controller Communications Commands) and
CIP (Control and Information Protocol). The data is stored in the exchange FBs and can be used in any
control strategy. Exchange FBs can also be used to exchange data between two Control Processors in
different Server domains, because these protocols support direct ControlNet addressing. Both controllers
would be interconnected through a separate ControlNet or Ethernet network, referred to as Auxiliary
peer-to-peer communication network (FTE does not support bridging).
In addition the Data Highway plus network of Allen Bradley is supported for communication between a
C200 controller and an AB PLC through the AB DHRIO module (purchased separately).
