Premise
The Modbus protocol is a standardized Application Level (OSI Level 7) protocol used in interoperable Industrial Control networks. Modbus provides the communication infrastructure necessary to integrate products manufactured by different vendors and to integrate control services that are now independent.
This document describes the present status of Modbus communication profile for all MicroTech III application software, providing the necessary information to incorporate a MicroTech ^ III Chiller Unit Controller into a Building Automation System (BAS).
Modbus terms and principles are not defined. Refer to the appropriate specifications for definitions and details.

Compatibility
The MicroTech III Chiller Unit Controller conforms to the published Modbus standards. 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.
This section describes the information that assure compliance of Microtech III to the integration criteria for a Modbus network integration. The data/alarm points that represent the minimum integration data points are listed in Table 1 below and in boldface in Table 2 to Table 5.
