Input channel configuration Via configuration software screen or the user program (by writing a unique bit pattern into the module’s
configuration file). Refer to your controller’s user manual to determine if user program configuration is
supported.
Calibration The module performs autocalibration on channel enable and on a configuration change between
channels. You can also program the module to calibrate every five minutes.
