Configuring the PLC for Fisher PROVOX

D-5

TIWAY I Gateway User Manual

The

-memory block now has 9 data words (plus the status register) in each

PLC. From the 64-register limit, you would calculate that there could be a

maximum of 7 PLCs (64/9 = 7) configured like this and connected to a single

PCIU.

The following Relay Ladder Logic (RLL) programs for your Series 500/505 or

PM550 PLC will block and unblock data to be accessed by way of the

network.
