Weighing module MW-01 is designed as a response for the growing market demand for industrial weighing systems based on load cells, where the weighing platforms are located in large distance from a controlling terminal.
Depending on the needs, communication with the module can be conducted via RS485, RS232, Ethernet, or Profibus. Module MW-01 series is intended to coooperate with terminals PUE 5, PUE 7 series or a PC.
The MW-01 enables full operation of PLC programmable controllers which communicate through communication protocol Modbus class 0.
The weighing module in network utilizing Modbus standard operates as slave, on one of available interfaces, RS 485 or Ethernet.
The MW-01 can operate in one of three modes:
RS484 - RTU, (hardware interface RS485, frame RTU),
TCP/IP - RTU, (hardware interface Ethernet, frame RTU),
TCP/IP - Open ModBus, (hardware interface Ethernet, frame Open Modbus).
Major applications of the weighing module MW-01:
Weighing systems which may be supervised by master computer system owing to comunication established using Ethernet interface.
Connecting a higher number of weighing platforms to indicators and terminals
Application in checkweighers owing to high processing power of up to 1000 measurements per second
Application in dosing systems.
