Hi everyone. 

I've got a topic module with next HW config: 4-20 4DMU. In CFC the input driver(PCS7AnIn) getting the value from this module. When current on channel module is less than 4 mA then on input PCS7AnIn block i get a value > 16#7CEE(22.5mA). If current on channel back to > 4 mA then input driver(PCS7AnIn ) taking a normal value.

It expected that a decrease in the current channel module, up to 0 (wire break), I get value on output PCS7AnIn less than the minimum value of engineering setting.

example: temperaure : 0-100°C,  input 4-20mA.

Expect: input 2mA, then T= -12.5°C, Real : input 2mA then T= 115.6°C

Hello,

only this little Picture about values.

New question published by UrielDM is split to a separate thread with the subject Can read secondary and third HART variables with ET200M?.
