micapp Posted October 31, 2016 Report Share Posted October 31, 2016 I am trying to set up a connection with a webserver over GPRS. I have a DNSserver set up to connect the PC and Unilogic PLC, but can not reach the PLC. Over ethernetconnection it works perfect. Any suggestion? I can send emails and the enfora modem receive GPRS IP Link to comment Share on other sites More sharing options...
Saragani Posted November 1, 2016 Report Share Posted November 1, 2016 If you just enter the IP of the PLC, does it work? Can you ping the IP?, And you ping the Domain Name? (you are using a DNS Server, so I'm guessing your PLC has a static IP and a domain name attached to it) Does VNC connection to the PLC works over GPRS? Sending an email makes the PLC open a connection from the PLC to a Mail Server, while connecting to a web server on the PLC requires connections to the PLC.
