Hi all Does anybody use wavecom fastrack supreme modems ? if so has anybody had the problem when trying to initialize modem it fails at AT+CREG (Network Registration) have 10 to 20 out in the field working but am increasingly having this problem even when the signal strength is 30. Will initialize one time and then wont 1 minute later after reboot have tried the sim card out of my mobile which works on other modems, Im getting to the point where I want to test the aerodynamics of the modem.

Hi Has anybody else had trouble updating the operating system for a jazz Im able to download and upload program, get plc information from jazz but when I try to update o/s comes up with unable to communicate doesnt matter what communication settings I use?

Damian The V570 is in control of the master pump in requards to start/stop running pressure ect but the master pump controls the slave pump and spare master, as for using the spare ports on the V130 its 300 meters away running 3 seperate pumps I could use it then it means V570 down to V130 Canbus then back to the building where the V570 is on modbus to control pumps, the plcs control cabinets are on different supplies. Think its just easier to convince the customer to change slave pump to another master then set all pumps to run seperate of one another and do all the controlling through the V570 ladder logic in reguards of which pumps to run.

Thanks for replies Basic problem is that 3 pumps work as a group (one master pump controlling a dumb slave and a spare master) pumping to one place the fourth needs to pump to another, according to the pump expert if I connect all pumps on one modbus the pumps will be a group of four even if I give seperate modbus Id's. Think the only way around is to replace the dumb slave as a master as well then will have all masters and can put on one modbus system and control as seperate pumps through the ladder logic. Life would be so much easier if customers ask for input during design phase. Oh yeah Damian these pumps can work on a cascade mode if one master pump cant keep up that pump will automatically start up the slave pump without any outside input control needed ,also using canbus to communicate with a V130 300 meters away so only have one com port avaiable for controlling these pumps.

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. Thanks
