Identifier for channel 1 or channel group 1
Channel-specific errors for channel 0:
Configuration / parameter error
HART parameters have been modified
(signaled by connected field device)
Wire break

Please note the following point:
SIMATIC S7 HART Analog Modules
Channel-specific error for channel 1:
Assignment corresponds to channel 0,
see byte 8
If a HART channel error occurs, you can obtain further information by
using SFC59 to read the status in the HART response data record for the
relevant client (see Section 4.8.3 ) or the additional diagnostic data record
for the relevant channel (see Section 4.8.4).
