2 Functions of Devices in DVP-PLC DVP-PLC Application Manual 2-58 ES SA Off STOP RUN EH2 EH3 Special D Function EX SX Attribute Latched Default SV SV2 SS SC On RUN STOP D1089 ↓ D1099 Process of data for Modbus communication instruction. When the RS-485 communication instruction built-in the PLC is executed, the words of the instruction will be stored in D1089 ~ D1099. You can check whether the instruction is correct by the contents in these registers.
