Description
This Function Block sets the chosen input type (see the table below), acquires the
input data from the module and returns the value using the "ChX" signals in engi-
neering units (°C or mV). As inputs the FB wants the network connection, the
node identifier and the type of the sensors connected.
Input tables
The configuration of the module inputs is done using the following strings. For
example, if the value “TCJ” is assigned to the signal "Ch1Type", this means that
the input channel 1 is configured as a thermocouple J.
