I downloa Temperature meter temperature Temperature meter control meter and CP1H PLC protocol macro communication video, there is a problem. The current value of the temperature control table is stored in the 4 bytes of the DM500 (W (D500, 4)) in the protocol macro software, while the value of DM501 is PV when the PLC is monitored, and the value of DM500 is about. Why PV value is not displayed in DM500.

This phenn communication is communication normal
PLC high byte in channel before ~

How does ariable communication in communication the CX-Protocol software receive data?

How does the variable in the CX-Protocol software receive data?
Receive data to select the variable Variable, and then choose to write Write W (select data address DM500, Y and N are 0, data length of 4)

See attac, communication is communication the variable set?
