5.2 Wiring unused channels on analog input modules
Rules
Pay attention to the following instructions when wiring unused channels:
● "Disable" unused input channels when setting parameters.
● A disabled channel always returns the value 7FFFH.
● The cycle time of the module reduces by 80 ms (e.g. 84 ms) per disabled channel.
● To adhere to the permissible potential differences, you must wire jumpers on the terminal
module for the unused channels.
