1.3.2 CONNECTING DISCRETE SIGNALS
Discrete signals are registered in sequential control blocks: An input is approximated to a relay, while an output is to a coil.
Inputs and outputs are represented in logic sequence commands. One block can contain at the maximum of 89 commands.
Multiple blocks can be connected in serial to handle more commands. At the maximum of 1068 commands (12 blocks x 89
commands) can be registered.
