  1. Thanks Keith I have checked SIM cards carrier. They are both 2G. But there is some progress - in fact what helps was the fact that I installed both SIM cards from the same provider. But to download 5000 records in Data Tables at 9600 baudrate it takes more than 12 minutes. How to solve this? You can imagine how long would it take to download new firmware from PC to PLC via two GSM modems at 9600. Do you have any solution? Regards
  2. Hi 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.
