If you enable diagnostics for multiple channels, you will receive an alarm surge on failure of the supply voltage because
1)
each enabled channel will detect this fault.
You can prevent this message burst by assigning the diagnostics function to one channel only.
When "Wire break" diagnostics is disabled, the current limit of 1.185 mA applies to the value status. For measured
2)
values below 1.185 mA, the value status is always: 0 = fault.
You can set the effective range of the diagnostics for each channel in the user program with data records 0 to 7.
3)
You can set the current limit for wire break diagnostics, the "Hardware interrupt" parameter and the hardware interrupt
4)
limits in the user program with data records 0 to 7.
