Hello! I am new here.
I have an object with such structure:
Building 1 = Eka1 = E1:
V570 - IP address 192.168.186.3 , PLC name = PLC1, can id #1
V120 - can id#2
V120 - can id#3
V120 - can id#4
V120 - can id#5
V120 - can id#6
V120 - can id#7
Building 2 = Eka2 =E2:
V350 - IP address 192.168.186.4 , PLC name = PLC2, can id #1
V120 - can id#2
V120 - can id#3
Building 3 = Izolators = Izo:
V350 - IP address 192.168.186.5 , PLC name = PLC3, can id #1
V120 - can id#2
V120 - can id#3
V120 - can id#4
Data between V120 and V350, or V120 and V570 sends with Unican. In most cases there is no problems with this transfers,
But week ago started problems with UDP_RAW sending between E2 V350 and E1 V570, and between Izo V350 and E1 V570.
Here is image of VisiLogic programm: in program i try to UDP_RAW scan IP address 192.168.186.4 (start vector MI1170), but when i online connect to V570 he shows IP address 192.168.186.5?! WHO changes number in MI1173 (i put 4 here , but in online mode 5!!!), if i use this MI only one time in a programm...
I checked SB141-146 in Izo_V350 , there was "1" in this system bits.
I checked SB141-146 in E1 V570 , there was "1" in this system bits.
I think E1 , E2 and Izo connected to a single network with switch. Also PC with 192.168.186.2 IP address connected to this netowrk.
I can ping 192.168.186.3, 192.168.186.4, 192.168.186.5 from PC in command line.
What i should check next? Ty for advices.
