Modbus communications

Just a quick reminder that all Unitronic OPLC’s can be either a master or a slave on a Modbus network.  All products support Modbus RTU over either RS485 or RS232 and if you fit an Ethernet card then Modbus TCP is also available.
We are happy to assist in developing communications to new devices however training courses can be provided to those who wish to write their own applications.  Some of the devices we have connected to are listed below.

• Dungs MPA4112 automatic burner controller
• Deep Sea 9470 battery charger
• Computronic Sentinel 300P battery charger
• Carlo Gavazzi VMU-E DC energy analyser unit
• Mitsubishi Electric D700 inverter
• Industrial Interface Z-PORT-RS Isoslice gateway
• Allen Bradley Micrologix PLC

Project: Automation and SCADA System for Water Treatment Plant

PLC: Vision560™, Vision1040™ + 300 I/O

Application: The automation system permits the ability to real time monitor the process and complete control of the Water Treatment Plant. All the field equipment is connected to the PLCs: pressure, temperature and flow transducers, the power controller and the control valves. The software application from the PLC has PID loops and permits to exchange the values of the parameters with other devices from the automation system. The PLC is connected and communicates with the Citect SCADA system via UNI OPC Server.
