The Logic Command provides information about what functions are
currently executing. You can access the individual bits of the Logic

You cannot change the values shown in the Logic Command by
directly accessing the parameter. Instead, the Logic Command
receives information from the logic evaluation block.
The logic evaluation block can receive information from up to seven
sources. The logic evaluation block takes this information and
combines it to form a single logic command word:
SCANport 1
SCANport 2
SCANport 3
SCANport 4
SCANport 5
Channel A (port 6)
Channel B (port 7)
Logic Command
(Parameter 52)
Logic Evaluation
Block
P367
P368
In this figure, notice that there are five SCANports and two channels
that can provide information to the logic evaluation block. You can
attach any combination of Human Interface Modules (HIMs),
Graphic Programming Terminals (GPTs), and/or SCANport
communications modules to any of the five SCANports.
Note: SCANports 1 and 2 are always available directly from the
PLC Communications Adapter Board. To access SCANports 3, 4,
and 5, you need to attach a SCANport Expansion Board to your PLC
Communications Adapter Board.
