1784-PCIC(S) configuration

This hardware driver applies to the Rockwell Automation 1784-PCIC(S) device. When you select a 1784-PCIC(S) ControlNet Driver to add or edit, RSLinx Classic opens a

Configure 1784-PCIC

dialog box.

RSLinx Classic accesses the device driver for the 1784-PCIC(S) card via the Rockwell Automation Virtual Backplane. The Virtual Backplane is a driver that provides communication between applications and device drivers that use the CIP protocol. When you select the RSLinx Classic 1784-PCIC(S) ControlNet Driver to add in the

Configure Drivers

dialog box, RSLinx Classic first attempts to register itself as a module in Slot 0 of the Virtual Backplane, and then attempts to register the selected 1784-PCIC(S) card as a module in the next available slot.

The card serial number is used to distinguish between multiple 1784-PCIC(S) cards installed in the same PC. When you select the 1784-PCIC(S) ControlNet Driver to add, the

Configure 1784-PCIC(S)

dialog box lists the 1784-PCIC(S) cards found, which have not already been assigned to another RSLinx Classic 1784-PCIC(S) driver.

All packets sent over ControlNet to this address are handled by the card. If an additional path is provided, the card bridges out Port 1 to the Virtual Backplane, allowing packets to be sent to RSLinx Classic (in Slot 0) or other modules registered in the Virtual Backplane. It is important to remember that CIP packets sent over ControlNet to RSLinx Classic via a 1784-KTC(X) card must be sent to the card with a dummy path segment, specifying Port 1 and Link Address 0. Thus, the 1784-PCIC(S) card can serve as a drop-in replacement for a 1784-KTC(X) card in these routing situations.

The 1784-PCIC(S) card does not support KT Emulation. Thus, PCCC requests sent to the 1784-PCIC(S) card over ControlNet are not forwarded to RSLinx Classic. Instead, PCCC requests must be routed to RSLinx Classic explicitly, as described in the previous sections.
