I have Simatic 400 station with one rack, 3 S7-414 CPU and Industrial Ethernet communicationing module CP441-1. Simatic CPU's are using in multicomputing mode. I want to create PC application which execute data exchange with each CPU.
As I understand, for data exchange with Simatic CPU by Industrial ethernet using Nodave I must to configure 3 parameters for this connection:
1) Rack number;
2) Slot of CPU number;
3) IP adress of CP441-1.
Can I create 3 connections with this parameters:
1) Connection with CPU1: Rack number, Slot of CPU 1 number, IP-adress of CP443-1;
1) Connection with CPU2: Rack number, Slot of CPU 2 number, IP-adress of CP443-1;
1) Connection with CPU3: Rack number, Slot of CPU 3 number, IP-adress of CP443-1.
In other words, CP-441-1 in Simatic system with muticomputing associate with only one CPU. In this case CP443-1 must work
in router mode (router on internal bus of rack). Can I use nodave with 3 connection for each CPU or I must
collect data in one CPU assciated with CP443-1 from other CPU and communicate only with this CPU by Nodave?
