How can I use Modbus to check the SCADAPack x70 device's RAM battery voltage, CPU temperature, and input power supply?
- Create new project using RemoteConnect.
- Under the My Network view, SCADAPack x70 Controller Settings-DeviceDTM, Right Goto Additional functions then select project settings. Enable Modbus IP Server and Modbus RTU Client for Modbus/TCP or Modbus RTU communication. Click Ok.
- Go Online with the SCADAPack RTu.
- Under Configuration-SPx70 controller>objects, select Object Configuration.
- Click on Add object. Type Name: RAM_Battery_Voltage, Association Tab, Source Type: System data, System Data Reference, Sys_Info and type: MemoryBatteryVoltage then click Ok.
- Click on Modbus Tab and assign modbus register 30001 and Modbus Data Type: Real, this uses 2 modbus address then click OK.
- Click on Add object. Type Name: CPU_Temp_Celcius, Association Tab, Source Type: System data, System Data Reference, Sys_Info and type: CPUmoduleTempC then click Ok.
- Click on Modbus Tab and assign modbus register 30003 and Modbus Data Type: Real, this uses 2 modbus register then click OK.
- Click on Add object. Type Name: CPU_Temp_Fahrenheit, Association Tab, Source Type: System data, System Data Reference, Sys_Info and type: CPUmoduleTempF then click Ok.
- Click on Modbus Tab and assign modbus register 30005 and Modbus Data Type: Real, this uses 2 modbus registers then click OK.
- Click on Add object. Type Name: Power_Input_Voltage, Association Tab, Source Type: System data, System Data Reference, Sys_Info and type: InputSupplyVoltage then click Ok.
- Click on Modbus Tab and assign modbus register 30007 and Modbus Data Type: Real, this uses 2 modbus registers then click OK.
- Configure the proper Byte Order, selected example is High byte/High word first (1234), this mimic Telepeace firmware. The byte order 3412 mimic the SCADAPack E series and Isagraf firmware.
- Click Apply button and Write configuration to the RTU.
