    Hello,
    Could you make a screenshot of the Modbus template, device data page and copy request and response as text?

    Hi….At the point when you say the CPU sends information through Modbus/TCP to SCADA that would deciphered as Modbus ace/customer composing information to the worker/slave SCADA framework, rather than the SCADA framework ace/customer perusing the information from a worker/slave PLC.

    About close to 100% of genuine, gliding point information in Modbus is 32 bit IEEE 754 drifting point (FP) values, containing two 16 bit Modbus enrolls in IEEE design. The other 1% is 64 bit skimming point information. At the point when you notice, “two words” I am speculating that you mean two 16 bit Modbus registers that will hold the 32 bit FP information.
