Hi all,
This post will be long but I want to give you all details about my problem. First lets say that the application was running well but since monday no communication is working.
I have a SLC 5/03 connected to an Ethernet network via a NET-ENI card throught RS_232. This Ethernet network has about 20 other AB PLC and all of them are read bu a RSView32 application. The comm with all the other PLC are OK.
First I went to see the PLC and observed that the LED for RS-232 comm on PLC was not flashing. I unplugged the RS-232 cable from PLC and connected my PC, went online allright. So I supposed my RS232 port on PLC is ok.
Next I plugged my PC in the Ethernet switch and tried ping the NET-ENI ethernet address. Worked ok again.
Then I tried to upload NET-ENI config via serial port to my PC, that didn't work.
On the RSView32 side, in RSLinx v2.51, I can see the PLC ok. When I start the runtime, the first page is a menu for all the PLCs, and mine was ok because there is one value on the button that is displayed and it was ok. As soon as I clicked on the button to reach the detailed page, comm failed and wouldn't come back.
I also did a OPC Test Client, the quality was bad. I changed the NET-ENI for a new one, now with OPC Test Client, quality is good, but still the same problem with RSView32.
Also I have a trend on the detailed page and I can see that as long as I don't click on the button on the menu page, I get the analog values from PLC. But when I get to the detailed page... comm fails.
I called Rockwell support and they can't help me. So I wondered if maybe some of the experts here could give me some advice.
Thank you.
Marie
