Channel 1
20…39 HART variables same as for channel 0
Channel 2
40…59 HART variables same as for channel 0
Channel 3
60...79 HART variables same as for channel 0
If HART is not enabled or the respective HART variable is not supplied from the connected 󹪝eld
device, the corresponding variable = 0 and the QC = 0x37 (initialization value from the analog
module).
A.6.7 HART-speci󹪝c settings
HART communication is available via standard parameter assignment.
Additional HART-speci󹪝c settings can be de󹪝ned channel-speci󹪝c via the data records 131...134.
The parameters set in STEP 7 are not changed in the CPU, which means that the parameters set
in STEP 7 will be valid again after a startup.
Every new parameter assignment of the analog module resets the HART-speci󹪝c settings back to
the initial values from parameter data record 128.
