Notes on Available PROFINET Controllers

1.4.1
Each PROFINET I/O Network is controlled by one or more PROFINET I/O Controllers. PROFINET I/O
Controllers may be GE products or third-party products.
GE Automation and Control offers the following RX3i PROFINET Controllers:

IC695PNC001: this is a rack-based intelligent module located in a slot of the host RX3i CPU rack.
The host CPU may be equipped with a maximum of four IC695PNC001 modules.

The IC695CPE330 provides an optional embedded PROFINET Controller. To utilize this feature,
LAN2 must be configured as a PROFINET Controller. In addition, the IC695CPE330 may host a
maximum of four IC695PNC001 modules in its CPU rack.

The IC695CPE400 also provides an optional embedded PROFINET Controller. To utilize this feature,
LAN2 must be configured as a PROFINET Controller. Since the IC695CPE400 is a Rackless CPU, it
cannot host any IC695PNC001 modules.
Each of the RX3i PROFINET Controllers mentioned above is capable of controlling a PROFINET I/O Network
containing PROFINET Scanners supplied by GE or by third-party vendors. Many vendors also supply I/O
devices that connect directly to the PROFINET network.
For PROFINET Controller product details, refer to the PACSystems RX3i PROFINET Controller User Manual,
GFK-2571.
