Before I oaded CP1H a CP1H OMRON temperature control table 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.

Refer to the Chinese manual page 98, D500 is a high word, in view of the thermostat PV will not be great, so in the D501 value, D500 value, the results are correct. (English manual error)
