RSLinx Enterprise & RSLinx Classic serial port conflict

Hi,

I have successfully interfaced a Micrologix 1400 and my panelview 1000. In the process I used the RS-232 DF1 driver/port to communicate with the PLC. Ethernet to communicate with the PV 1000. At some point I had to disconnect RSLinx Classic so that RSLinx Enterprise could communicate with the PLC as well.

The problem I have is that I need to go back to RSLinx Classic, so I can edit the PLC code. But RSLinx Enterprise is still using (Mode: Online) the RS-232 DF1 driver. How do I stop/prevent RSLinx Enterprise from using the driver OR how can I use my RSClassic without this Serial port conflict?

Thank you,

I assume you're speaking of the PC that you're doing development with.

Kill the RXLinx Enterprise process using the task manager.

OR

Why not but a simple ethernet switch between the PLC & HMI and connect your PC to it also using the its ethernet port. I always carry with me a small switch that I can insert in small standalone systems that don't have a switch so that I can have fast comms and avoid scenarios like you describe.

jstolaruk, thanks so much for your reply. I knew I should have used an ethernet switch to ease communications. Anyways, i followed your suggestion and the PLC & Panelview are communicating and I still can go online on the computer with the PLC. Perfect!

I am still however, having trouble with the conflicting ports. Using the Task Manager on the computer to turn off RSLinx Enterprise does not work...RSLinx E. is not there. Any other suggestions? I deleted the RS-232 DF1 driver from RSLinx Enterprise communications windows on FTV.

No, and I just had this scenario a week or so ago and didn't run in to it. The only thing I can think of is to reboot the pc, startup rslinx and connect using the serial port to the processor with rslogix Then start factory talk view studio.

jstolaruk, I found the answer to Stop RSLinx Enterprise Service:
1. Go to Control Panel-> Administrative Tools-> Services.
2. Double-click on RSLinx Enterprise and on the left side of screen click on "Stop" the service.
3. The same procedure can be used to "Start" it.

Thanks for the tip!

Once you get RSLinx E stopped you might still get a port conflict message. If you do go into device manager and disable then re-enable the com port. Window sometimes likes to keep an association even though the software has stopped running (especially when it’s a service like RSL. E.). Disabling the com port breaks the association and frees up the port.

Why not just get a USB to Serial adapter and use that as another port?
