Currently facing some problem with the 1796-L35E controller.. RSLinx can't communicate with the controller. Will appreciate any advise..
Basically, On initial setup, I use BootP to assign an IP address to the PLC, then disable the bootp.
Then, I open RSlinx and use the driver configuration to setup an Ethernet device driver and entered the IP of the PLC.
After that, I use RSlogix5000 to update the firmware and download a program into the PLC. All seems fine and no issue. Then the machine was switched off for the weekend.
However, Today, somehow, the RSlogix5000 is unable to communicate with the PLC. I open RSLinx and RSWho to test the connection and it just doesn't seems to connection. Basically, it kind of "hang".. the animated icon appears like trying to connect, but it remains in that state. It doesn't show a "X", and no error message like "Unrecognized device" etc.. but just appear like attempting to connect.
I tried to ping the IP of the PLC and there is a response.
I tried removing the driver and add a new one. but the result is the same.
I test the laptop with another machine using contrologix, no issue, can connect (different IP)
I test using cross LAN cable direct connect to the PLC, result is the same. got ping response but RSlinx cannot connect.
Anyone can help?
In summary
1. Ping the device, got response.
2. RSlinx can't communicate with the PLC. Under RSWho, Like always trying to connect. No "X" and no error message.
Thanks.
