Chapter 8 - Fieldbus communication (option)

8:1.3.3 Diagnostic inputs

There are 3 channels available for fieldbus related diagnostic messages. Each

channel consists of two bytes with an error code and the parameter number that

caused the error. The latest error is stored in channel 1, the second latest in

channel 2 and the third latest in channel 3. The binary output bit “reset active

diagnostics” is used to clear the diagnostic area.

Error Codes:

1 = Parameter Value out of range.

2 = Invalid parameter number.

3 = Write parameter when fieldbus control is not enabled
