W0202

Has been built to allow extension of RS485 bus using wireless technology wherever use of network cable is impossible or unprofitable. Use of two W0202 allows to build the wireless 'bridge' for the RS485 by building wireless remote island (one or more) for devices communicate via Modbus RTU/ASCII - eg. MIX series or MINI series I/O modules. W0202 in addition to the RS485 port and wireless port is equipped with 2x SI (Special Inputs) and 2x DO (Digital Outputs), which allows to use device as I/O module or light controller communicating in Modbus RTU/ASCII. Implemented algorithm in the processor allows user to choice one of different modes:

• Modbus Bridge
• Modbus Bridge and I/O module (both DO work independent of the state of SI)
• Modbus Bridge and I/O module with built-in algorithms for light, cooling or heating control.
• Modbus Bridge and I/O module with present sensors support.

W0202 is also equipped with a micro USB port which allows to configure it without the external power supply (the device is powered through the USB port). This solution gives user an easy way to carry out the tests within the existing facility.
