I’m looking to create a tag through a Modbus list through a Schneider 5110 device. Its showing that the data type is “4Q FP PF” which were not too sure how to set up. The images below show the registers and the data types.

The standard modbus format type required should be "PF32". From looking at the modbus formatting code this seems to do a similar calculation for PF_Val as described above.

If the MDI does not support this format then use the IEEEFloat type and then hand edit the generated .xml file to change from IEEEFloat to PF32 for those registers.
