Measuring types and ranges
Introduction
The module has a default measurement type resistance thermometer RTD (4-wire
connection) and the measuring range Pt100 Standard. You need to reassign the module
parameters with STEP 7 if you want to use a different measurement type or range.
You use temperature coefficients to determine the measuring ranges for resistance
thermometers / thermocouples according to the GOST standard. You can find the adjustable
temperature coefficients in the Parameter assignment and structure of the parameter data
records (Page 56) section in the table Coding for temperature coefficient.
You can find the analog values for the usable resistance thermometer / thermocouples in the
sections Analog value representation for resistance-type transmitters / resistance
thermometers (Page 74) and Representation of analog values for thermocouples (Page 80).
The following table shows the measuring types and the respective measuring range.
