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.
You can set the effective range of the diagnostics for each channel in the user program with data records 0 to 8.
2)
The setting is only possible for channels 0 to 7. If you use the "Reference channel of the module" setting for at least one
3)
channel, you need to operate channel 8 with the resistance thermometer RTD measurement type.
You can configure the "Fixed reference temperature" setting and the limits for hardware interrupts in the user program
4)
with data records 0 to 8.
