Bits 10, 11: Behavior after I/O module timeout
The reaction depends on register 32, bit 2.
Bit 11 Bit 10

* Output 0 V or 0 mA. This is achieved by switching off the
scaling and calibration mechanisms and outputting values
according to the operating mode, which produces approximately
0 V with an imprecision in the lower two-digit millivolt or
microampere range.

Bit 12: Reserved
Bit 13 .. 15: Switch-on delay
The switch-on delay is the time that should pass after an ongoing overtemperature
error of the output driver until the error state is left. This way, for example, pulsing
can be avoided, which otherwise could be misinterpreted by the actuator as a strong
value change.
The values of the time fluctuate by ±10ms.
