  • Page 169: Register Read And Write

    APPENDIX. HOST COMMUNICATION PROTOCOL A.3.6 Register read and write  Read holding registers [03H] The query message specifies the starting register address and quantity of registers to be read. The contents of the holding registers are entered in the response message as data, divided into two parts: the high-order 8-bit and the low-order 8-bit, arranged in the order of the register numbers.
  • Page 170 APPENDIX. HOST COMMUNICATION PROTOCOL  Preset single register [06H] The query message specifies data to be written into the designated holding register. The write data is arranged in the query message with high-order 8-bit first and low-order 8-bit next. Only R/W holding registers can be specified.
  • Page 171 APPENDIX. HOST COMMUNICATION PROTOCOL  Diagnostics (Loopback test) [08H] The master’s query message will be returned as the response message from the slave (SRZ unit). This function checks the communication system between the master and slave (SRZ unit). Example: Loopback test for slave address 1 Query message Slave address Function code...
  • Page 172 APPENDIX. HOST COMMUNICATION PROTOCOL  Preset multiple registers [10H] The query message specifies the starting register address and quantity of registers to be written. The write data is arranged in the query message with high-order 8-bit first and low-order 8-bit next. Only R/W holding registers can be specified.

    APPENDIX. HOST COMMUNICATION PROTOCOL A.3.7 Caution for handling communication data  The numeric range of data used in Modbus protocol is 0000H to FFFFH. Only the set value within the setting range is effective. FFFFH represents 1.  The Modbus protocol does not recognize data with decimal points during communication. Example1: When Heater break alarm (HBA) set value is 20.0 A, 20.0 is processed as 200, 200 = 00C8H Heater break alarm (HBA)

    APPENDIX. HOST COMMUNICATION PROTOCOL A.3.8 How to use memory area data Memory area function can store up to 8 individual sets of SVs and parameters. One of the areas is used for control, and the currently selected area is “Control area.” Memory area data can be used to check and change settings that belong to memory areas other than the control area.

The memory area number, “2” is written to the CH1 setting memory area number (386CH). Data in Memory area 2 is called up to the CH1 register addresses. CH1 register addresses Setting memory area number 386CH...

The area (095CH to 0E5BH) now used for control is called “Control area.” The memory area number (control area) can be changed at either RUN or STOP. Register address CH64 ...
