Issue TC300 Series Networking Digital Fan Coil Thermostat - Modbus Protocol Documentation Product Line Field Devices Environment TC300 Series Digital Fan Coil Thermostats Cause Modbus protocol information is needed in order to perform Modbus integration to the TC300 Series Digital Fan Coil Thermostats. Resolution The TC303 thermostats come with the option of Modbus communication for both 2- and 4-pipe configurations. Modbus is an open, widespread and well established serial communication protocol used within building automation. The support of Modbus communication allows simple integration of the TC303 thermostats to a building management system, using standard Modbus serial communications. The following models provide support for Modbus connectivity: TC303-3A2LM TC303-3A4LM TC303-3A2DLMS TC303-3A4DLMS TC303-3A2DPMS TC303-3A4DPMS The TC303 thermostats communicate as a Modbus RTU slave device over a serial RS-485 connection, allowing for the transfer of real time data. Thermostats manufactured from November 2018 (2018-W44-4)* onward can be configured to communicate at 9600 (default) or 4800 bps. The communication parameters for TC-300 thermostats manufactured prior to this date cannot be adjusted and are fixed as follows: 4800bps Baud Rate 8 Data Bits Odd Parity 1 Stop Bit The actual Modbus address of the thermostat can be set for each individual device on the RS-485 network. The address is defined via the parameter menu on the thermostat itself. The address range available is from 01 to 32 and is defined under menu item 04 of the parameter settings. For full details on this, other parameter setting options available and Modbus communications parameters/registers, please refer to the Installation Instructions.  Connection to the RS-485 network is made via dedicated terminals on the back of the thermostat and marked A (+) and B (-).   TC300 Series Digital Fan Coil Thermostat Installation Instructions TC300 Series Modulating Fan Coil Thermostat Installation Instructions   * Note - The Installation Instructions have not been updated to include the information that thermostats manufactured from November 2018 (2018-W44-4) onward can be configured to communicate at 9600 (default) or 4800 bps. 

Issue TAC Xenta programmable controllers (28X, 30X, 401) can have trend logs stored in memory on the controller.  Each programmable device has a different amount of storage space allocated to trends. Product Line Field Devices Environment Xenta programmable controllers (280, 281, 282, 283, 300, 301, 302, 401, 401:B) Cause The settings of a Xenta trend log (how often a point is read, how much data is stored) need to be made with the memory capacity in mind. Resolution This information can be found on the following data sheets :  Xenta 280, Xenta 300, Xenta 401. Each of the programmables can hold up to 50 trend log definitions.  But the frequency of the polling and length of storage for the trends need to be altered.  The limitation in memory is how many data points can be stored, and is dependent also upon the data type. Trend Logging in the TAC Xenta 280 Total logging capacity approx. 650 floating point numbers   or approx. 1,300 integers   or approx. 10,000 digital values   Trend Logging in the TAC Xenta 300 (HW2 or higher) Total logging capacity approx. 4,000 floating point numbers   or approx. 8,000 integers   or approx. 60,000 digital values   Trend Logging in the TAC Xenta 401 Total logging capacity approx. 7,000 floating point numbers   or approx. 15,000 integers   or approx. 110,000 digital values
