Hi,
I'm unable to find this PLC using RSLinx 2.51.
I have configured my pc LAN port to be 192.168.1.20, connected the PLC to PC by a straight thru ethernet cable via a switch, found the plc (I think?) using BOOTP-DHCP Server and changed its IP address to a 192.168.5.5, BOOTP-DHCP then reports a connection to the device with this address, when I try to DISABLE BOOTP/DHCP I get a timeout error.
So I guess this means the PLC has the new IP address but will lose it when the power goes off?
So while the power remains on I hve tried pinging the new address and it looks ok.
I then tried both drivers in Linx (Ethernet Devices & Ethernet/IP Driver) but still cannot find the PLC. Using 'Ethernet Devices' I can see a device called 'Ethernet Gateway' (I think this is correct, I don't have the PLC right now), but cannot find the PLC.
I have no yellow question marks, I have the ESD files loaded, I have read the other posts about CompactLogix/Ethernet.
One niggle I have is that BOOTP-DHCP Server finds a device (I assumed to be the PLC) with a MAC address that is different from the MAC address printed on the chips inside the CPU. (I only have the PC, switch and PLC connected).
Can anyone suggest where I am going wrong?
