TIWAY I Gateway User Manual
The V -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.
