Dear All, As far as I understand, it is not possible to transmit 32 bit floating = point data or double integer data on the Modbus. We want to read 32 bit data through Integrator 30 on Modbus protocol from Allen-Bradley PLC. How can we read the data. Is there some calculation involved which = converts two 16 bit registers into 32 bit data.
