6.4 Setting system parameters for F-signal modules
Discrepancy handling (analog inputs)
In the processing industry, no evaluation is generally performed between 2 signals on the
module. 1oo1 is set for sensor evaluation. This makes all the signals available in the user
program, where they can be linked in 1oo2 or 2oo3, depending on what is required. If 1oo2
evaluation is to be implemented on the module, you can find the parameter description for
discrepancy handling in the online help.
HART
Here, you can switch off HART communication on specific channels in a non-safety-related
manner, as well as enable HART diagnostics options and determine how often the module
will attempt to establish HART communication with the transducer before a message is
issued.
In the case of HART devices for which parameter assignment cannot be interlocked, HART
communication must be switched off.
