Connect 2 LOGO! 0BA8

Hi,

I'm trying to connect 2 LOGO! 0BA8.

I have 2 PLCs and PC connected to switch, through switch I go to the router and then to the internet.

If I try to adjust IP address in TCP/IPv4 I'm not able to communicate with LOGOs at all. If I leave TCP/IPv4 at automatic I can see both LOGOs but I can upload program to only one of them.

I see both of them when I refresh list of accessible LOGO!s befor trying to transfer program.

One has IP 192.168.000.003 this one works 

Other           192.168.000.002 I get "Unable to accsess remote device" error for it 

Subnet mask is     255.255.255.0  for both of them

Gateway is 192.168.0.1 for both of them

If I connect them directly to PC with cable they work and I can upload program on them.

I'm not administrator so I'm unable to check/adjust router setings.

LOGO!s are version FS:04 and I have LCS 8.1

Hi

What is the IP address of your PC?

Hi

PC address is 192.168.0.27

Does the computer have same gateway and subnet mask, can you ping them?

Tried unpluging them?

Subnet and gateway are same as on LOGO!s

Ping results are in attachment.

I tried to unplug and again 192.168.000.003 is working, 002 is not working even when 003 is not connected to switch

OK, after unpluging and pluging cable from switch to router I can upload programs  to both PLCs

Now I need to make program to test this. :))
