Controllers can communicate on standard Modbus networks using ASCII or RTU transmission mode. The MicroTech III Chiller Unit Controller uses the RTU mode only. Refer to Ref.#1 for more detailed information. Configuring the Microtech III for Modbus Network The MicroTech III Chiller Unit Controller can be configured in an interoperable Modbus network. The controller must have the corresponding Modbus Communication Module installed. The MicroTech III Chiller Unit Controller and the Modbus Communication Module are shipped with default parameter values. Default values may be changed with the unit keypad. Parameters must be adjusted to accommodate your particular network. See the appropriate Operation Manual for default values and keypad operating instructions. See the MicroTech III Modbus Communication Module Installation Manual for details regarding network parameters available via the unit controller keypad/display. Once communication module is set up and communication with network is established, in order to control the MicroTech III over the network, the Unit control source must be turned in “Network” (default is Local). From keypad/display set the Main Menu_View/Set Unit_Status/Settings_Control Source to “Network”. Modbus Registers Addressing The Modbus Communication Module supports zero-based addressing. For example, holding register 40002 is addressed as 0001 in a Modbus message. The following tables assume 4xxxx addressing.D-EOMOC002(19)12-14EN - 6/35 Minimum Integration This section describes the information that assure compliance of Microtech III to the integration criteria for a Modbus network integration.
