Hi
I am using a Vision 130-33-TR6 and a GSM KIT 41J and I wish to allow remote access to the PLC using this kit.
However there is no phone signal at the PLC location so I was considering running a cable to another location with signal and placing the modem here. The location with phone signal is 400m away from the PLC location. I have been told that at high baud rates I cannot transfer data that distance but at a baud rate of 2400 I would be able to go up to 900m. Is this correct and if so would I still be able to access the PLC remotely at this baud rate? I assuming if so the project scan time would have an impact on this? Are there any other ways I could solve this problem?
Thanks
Adam
