I have V430-J-T2 and two GSM modems Enfora (GSM-KIT-41J). I would like to remote access operands, data tables,... from PLC.
Both modems are initialized properly, on PLC SB80 = 1 (modem initiailized on COM1). But any remote access failed.
Also COM port is properly initialized in ladder. But when I dial there is always either "Dial timeout exceeded" or "No carrier". SIM cards are enabled for GPRS data transmission.
One more thing - in Help there is written that Enhanced Vision (like V430) should have baudrate = 57600. But in that case there is never succesful PLC side modem initialization. Only in case that baudrate is 9600 initialization of PLC modem is succesful.
PLC OS is up-to-date.
Can you prepare an example that remote access with such hardware configuration is working.
