Take in mind also Why can't my SIMATIC S7-300 Ethernet CP run as many S7 communication connections as specified? Best regards, Hristo Mihalev

If you want to use 5 S7 Connections just for the interconnection of the PLC’s, this may get really tough. Personally I would recommend the use of OUC with T-Functions. In this special case the use of the ISO on TCP Protocol. Here you may have up to 7 Connections on each CPU without using one of the important S7-ressources. This is surely just my opinion. Best regards J_Bell
