Comunication made with s7 protocol suite - TCP-IP All Communications between those 10PLCs are OK Yesterday I've added a new plc (another S7400 with CP443-1 Advanced) and I can't communicate with this (error code in 'channel diagnosis' shows me 4104 (that means 'not enought resources') if I disconnect one of this 10 PLCs communication with this new PLCs works! I have these 2 licenses: RC64000 and WINCC Server In the 'Licenses Analsys' wincc doesn't require me other licenses Anyway I've added Industrial Ethernet SOFTNET-S7 Basis (with no results) any Idea? Thx in Advance
