Why are floats not detected when importing symbols from PG5 2.0.210?

FAQ #101709

When importing the symbols of a PG5 2.0 project into the OPC configuration the floating point registers are not correctly detected (if PG5 2.0.210 or earlier is used).

 

Symptom
When importing the symbols of a PG5 2.0 project into the OPC configuration the floating point registers are not correctly detected (if PG5 2.0.210 or earlier is used). Instead of floats they are configured as integers.

Reason
The symbol files generated by PG5 2.0.210 (and earlier) are missing the indication to be a floating point register (a {F} in the comment of the symbol). As this indication is missing, the OPC Server can not figure out it is a floating point value.

Solution
PG5 2.0.220 adds the indications again to the symbol files. If only an older version of PG5 2.0 can be used the following work-around could be applied: 

  • the configuration can be corrected manually by modifying the "Type" to "Float":
