Pass Through Setup - Allen-Bradley SLC 500 Manual

Pass Through Setup

Go to the Project Setup dialog box and select AB Remote I/O as the PLC. Click the Protocol button to
display the AB Remote I/O configuration dialog box. Select the PLC type and the Baud rate of the
network.
Each Quick Panel on the RIO can emulate one or more quarter racks. For Pass Through to work
properly, each Quick Panel must be assigned to its own full quarter rack. No other Quick Panel can
share emulation of a rack.
Select an unused rack and select a quarter rack for emulation by clicking the Observe button. Select a
BTW and a BTR for a single slot location and assign both to a length of 64. The slot is now setup for a
Block Transfer operation, which can be assigned to Pass Through.
Make sure the PLC does not use any BTW or BTR for the selected slot.
In the following example, Rack 2 has been selected. The second quarter rack, consisting of Group 2
and Group 3, has been selected for emulation. Slot 0 has been configured for a BTR of 64 and a BTW
of 64.
Click the Pass-through button to display the Pass Through dialog box.
