Color coding of optional inputs and outputs
The optional digital inputs and digital outputs can be identified by the color of the pin header:
black = digital inputs, gray = digital outputs. However, the terminal strips attached to the pin headers are
gray in both cases. If necessary, the terminal strip must be pulled off to identify the color of the pin header.
It must be ensured that this does not jeopardize the operation of the plant.
