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)

Logic Command

(Parameter 52)

Logic Evaluation

Block

P367

In this figure, notice that there are five SCANports and one channel

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

ControlNet Adapter Board. To access SCANports 3, 4, and 5, you

need to attach a SCANport Expansion Board to your ControlNet

Adapter Board.
