    6. COMMUNICATION DATA 6.1 Request Command and Data Transfer Data transfer between PLC and SR Mini HG SYSTEM are executed by request command. Request command “0: Monitor (PLC ← SR Mini HG SYSTEM)” Command which requests the SR Mini HG SYSTEM to write data such as temperature measured values, etc.
  • Page 18 6. COMMUNICATION DATA Data transfer procedures Change each set value of SR Mini HG SYSTEM from the PLC after the initial settings are made. If each set value of SR Mini HG SYSTEM is changed from the PLC without setting the initial values, it is re-written to 0 with each set value of the PLC at that time set to 0.

    6. COMMUNICATION DATA 6.2 Data Processing Precautions With PLC communication, the maximum number of channels per unit address is 20. Read data of unused channel and undefined address is 0. The data type is treated as binary data with a sign and without a decimal point. For this reason, carefully express and set the data.
