I would like to use GPS receivers to track the location of mobile equipment. This equipment uses a wireless network to connect to Modicon PLCs.
I would appreciate your recommendations and experience using a GPS receiver which supports Modbus/TCP communication.
How is your wireless network implemented to communicate with the PLC's?
The GT-540 has a GPS receiver and Modbus RTU over RS-485. It has software and API to create your own monitoring system or integrate withe SCADA.
