I have been asked to have a look at a job where they wish to control a diesel engine powered pump on a barge. There will be monitoring and control involved.
I was looking at using an Omron CJ1M PLC with a couple of comms cards, 1 input and 1 output card. Set up Modbus RTU comms to the Cummins engine, Modbus RTU comms to another barge and a small SCADA system to monitor and control.
The barge will only have the engine start batteries on board and I was looking at using a 24VDC powered PLC off the start batteries with a switchmode power supply between the batteries and the PLC.
Next problem - the barges could be up to 5 kilometres apart. Probably not good for line of site wireless - may have to shoot off a satellite.
Anyone have any suggestions/ideas/recommendations?
Any help would be much appreciated.
