It seems that the COM1 port (and all the other COM ports for that matter) is somehow failing.
Then, after a little while, the computer couldn't even connect to the PLC anymore. Again, we are running into the problem of RSView not recognizing the display (we know it was RSView, because RSLogix connected just fine). We have tried to fix the situation, but nothing seemed to work. First, the ethernet connection from the computer to the PLC stopped working (without any settings being changed). However, at that point we started getting other connection problems. Essentially, I walked into our team meeting today and the HMI was working perfectly fine. Hello Ken: Well, it seems like our problem is more deep rooted than that. We have the driver for the Serial-DF1 set to the following: Use Auto-Configuration NO Device PLC5 Error Check BCC Parity None Baud 19200 Stop Bits 1 Ack/Poll Timeouts 3000 Max Retries 3 Station number 0 COM Port 3 The ComplactLogix Processor Properties are: Address 1 Does anybody have an idea for what could be causing our problems? Thank you very much for your help! Jan
Within Networks and Communications, we were changing the settings of RSLinx Enterprise Communications, specifically for the tab Serial-DF1, under which our processor (CompactLogix 元1) is listed. Are there any settings which need to be specified before the HMI can run? We have gone through the options on the HMI, and the only category that seems to apply is the "Networks and Communications". We have tried several things, but are at a slight loss right now. We checked in the help files of the RSView applications, where it indicates that there is either a timeout, the controller is unavailable, or the controller timed out (the "controller unavailable" seems to be the one since the Channel 0 light on the PLC doesn't turn on even though the serial cable to the HMI is connected). The error that seems to relate to this issue is: (CLXDP) XIP Connection (0) open rejected (Error 2040101) on route to. We have managed to download the application to the HMI, but upon actually loading the application, the HMI seems to fail to connect to the PLC. We have also finished the HMI application (RSView Studio Machine Edition, release number 4.00) and are now trying to download the application to the actual HMI (Allen Bradley PanelView Plus 600) and use it to control the PLC. My team and I have essentially finished our ladder logic (designed in RSLogix 5000 v15.0.2 to control a 1769-元1 microprocessor with the following modules: HSC, OF4CI, IF4I, OW8I, and IA8I) and have tested it on our laboratory setup. Hi everyone: I have been asking many questions recently, and it seems like another one has to be added.
