The addresses shown are example-specific. Addresses for any given installation can be determined,
based upon the 1203-GD1 communication module switch settings for: rack address, starting group
number, block transfer, logic command/status, and reference/feedback by applying the I/O
addressing format for PLC-5 controllers.
