Posted 28 Mar 2019 Hello! I am trying to connect my PLC with SCADA. I am using S7-1200 1212C CPU (RELAY outputs). My SCADA system is iFIX 5.8 with driver S7A. I am trying to establish connection via GPRS router (TCP/IP). Port being used is 102 (default by S7A driver). In my company we have private network, SIM card in GPRS router gets static IP (set by RADIUS server) which is 10.247.XXX.XXX. My PLC has IP 192.168.0.10 set in Project. I am not sure what am I doing wrong. How to correctly set IP address in PLC to communicate in private network via GPRS router with static IP? I already enabled TCP port 102 in my router but I am not sure to which IP should I enable it because I am not sure if IP address set in PLC is correct. Should I use some communication blocks in program? I also enabled PUT/GET function (see attached pictures). Please help. Thanks in advance! :) Share this post Link to post Share on other sites
Posted 29 Mar 2019 I solved my issue. For further users: in S7A driver Dest. IP Address must be static IP set by RADIUS server fot private network. In TIA portal configuration is fine as it shows picture 1 (IP set in project). In router there must be port mapping configured: open TCP port 102 for IP address which you set in TIA portal.
