Inter-process Communication

The IPCom module is used for inter-process communication between two
programmable automation controllers.

With this module, the communication to a remote controller is set up and
supervising.

The main function of IPCom is to distribute the bus-data. At the same time, it
also transfers various numbers of user data, which can be allocated optionally
and, for example, used for interlocks and user data transfer to other
controllers.

The communication basis of the IPCom module uses the ControlLogix
system’s produced/consumed tags. After the programmer has created and
configured a produced/consumed tag structure, the IPCom modules plug on
to this tag, as a communication channel.

Produced/Consumed

Controller Tags

To establish produced/consumed controller tags, complete the following
steps.

Step1

To use the IPCom modules, you must first create and configure the link to the
remote controller.

Also, you must add the complete network, with all involved controllers, to the
I/O Configuration tree, in the RSLogix 5000 project.
