active Posted November 13, 2010 Report Share Posted November 13, 2010 Hi Hope someone can help on one of my jobs I've ran out of communications ports on the V570 using com 1 for modem (sms), com 2 for modbus and com 3 has an ethernet port for modem my problem is that due to the type of pumps that my customer bought I need three pumps on one modbus and another pump on seperate modbus only one lot of pumps will be running at one time, cant run them on one due to the three pumps using cascade control mode, third pump slave model so unable to run pumps as individuals. Trying to find a cost effective solution, does anyone know of a device that will allow me to use one master com port to plug into plc and switch between two slave ports going to the two groups of pumps or any other ideas would be appreciated.
