  • Page 4: Connection

    CoolMasterNet Modbus RTU Connection In CoolMasterNet Line L3 is recommended for Modbus RTU connection, although Lines L4, L5, L6 and L7 can also be used for that purpose. Picture above shows connection to Line L3.

  • Page 5: Modbus Ip Connection

    In CooLinkNet/CooLinkHub only Line L3 can be used for Modbus RTU connection. 1.2 Modbus IP Connection Modbus IP is supported in CoolMasterNet and CooLinkHub devices. Device acts as a Modbus Server, communicating on the Ethernet TCP/IP network. Physical connection in this case is made via RJ45 Ethernet connector.

  • Page 6: Configuration

    Modbus RTU interface module of the CoolAutomation device has to be activated by assigning appropriate communication Line. In CoolMasterNet it is highly recommended to use Line L3, although it is possible to use any of the L4, L5, L6, L7 lines. In CooLinkNet and CooLinkHub Line L3 usage for Modbus RTU is mandatory.

    Configuration. 2.3 VA's Configuration VA's are used in CoolMasterNet and CooLinkHub devices. For CooLinkNet device this chapter is not applicable. VA's -Virtual Addresses are used in order to simplify translation of the Indoor Unit identifier/number - UID into addresses of related Modbus objects: holding registers, input registers, coils and discrete inputs.
  • Page 8 UID L1.102: >va + L1.102 0004 In this case UID does not have to be detected (visible) by CoolAutomation device at the VA allocation time. It is allowed to allocate a number of VA's for any given UID. To delete all allocated VA's: www.coolautomation.com...
  • Page 9 Alternatively all VA's associated with specific UID can be deleted (below command will delete all VA's associated with UID L1.102): >va - L1.102 Once VA's are allocated Modbus RTU and Modbus IP can be properly used to access Indoor Unit parameters via associated VA's. www.coolautomation.com © 2017 CoolAutomation LTD.
