Hi I'm working in a proyect to the Variadores S.A Company in bogota, Colombia. They need communicate the plc with the pc vía GPRS, ussing the program Remote Access and two ENFORA modems. I have two SIM CARDs one for the modem and one for the other. Claro S.A provides me two IP address whit a APN Server; this is a private network. In my program i have: - name of the PLC ---- Visio570. - Com init ---- i connect my modem in the port #2. - gprs configuration and gprs registration. int the grps registration I'm going to set a MI where the program save the ip address (this is the ip address of the MODEM PLC). You also have to set the APN Server. - IP to ASCII --- With This function Block the OPCL save your IP Address. -Start Call ----> I configured the remote tcp/ip port the number 20257 but i'm no sure about that (unitronics have a video with this proyect but in the video the por tcp/ip is 5000) I am confused about that. I also cofigured the ip addres of the second modem, the second modem is the PC modem. - end call -listen mode ---> i configured the port --- 20257. - end listen mode. -unregistered. I connected the network and inicializated the two modems, one for the PLC side modems and the other for PC side modems. when I turn on the plc and the modems, the plc save the modem ip address and displayed on the screen. when I pressing the button LISTEN, the bit connectect turn on.
