Cytech's new UCM/Modbus allows Modbus devices to be interfaced to Cytech's Comfort system. The UCM/Modbus can be programmed as Client/Master or Server/Slave on Modbus. Master mode is for Comfort to control other Modbus Slave products, and Slave mode is for other Modbus devices and software to control Comfort. Both modes are capable of 2- way communications, ie Comfort to Modbus and Modbus to Comfort
Modbus over RS485 (Modbus/RTU) and Modbus over IP are possible by plugging in the RS485 or ETH03 Ethernet submodule onto the UCM/Modbus baseboard.
The UCM/Modbus can work with other Comfort modules including Intelligent Remote Input/Output Modules (IRIO), Temperature Sensor Module (TSM01), Hotel I/O (HIO) as well as 3rd party systems on the Comfort Bus including C-Bus, KNX, Z-wave.
Configurable as Master or Slave on Modbus
Implements Modbus/RTU by RS485 and Modbus/TCP using plug in sub-modules RS485 or ETH03 respectively. RS232 is also possible for Modbus RTU
Comfort (CM9000), UCM/Logic, LGX01 Logic Engine can act as the central controller for UCM/Modbus
In /Master Mode: 256 Modbus addresses in Modbus to Comfort
For Modbus/RTU, baud rate selectable from 1200, 2400, 4800, 9600, 19200, 38400, 76800 bps. Parity None, Even or Odd
As Modbus Master, Comfort Counters, Flags, Sensors, Inputs, Outputs, security commands and alarm conditions can be accessed (read/write) by a Modbus Master
As Modbus Slave, Comfort Counters, Flags, Sensors, Inputs, Outputs, Alarm conditions can be accessed via Modbus Registers
Modbus Monitor mode shows the receive abd transmit communications between UCM/Modbus and Modbus. It works for RTU and TCP interfaces, as well as Master and Slave
Minimum System Requirements
Comfort Ultra/OPT or UCM/Logic or LGX01 Firmware 7.116 or above can act as controllers.
