Panelview 550 to SLC/03 Comms problem

[mrbj 0]

Hi, System PLC -- SLC 5/03 HMI -- Panelview 550 Connected cables From SLC 5/03 Serial Port to PV 550 Serial Port (RS232) From PC Serial Port via 1747 PIC to SLC 5/03 DH485 port. Software (old but usually works ok, have not had any problems before using it) RSLogix 500 V5.20.00 Linx Lite 2.31.00 PanelBuilder 32 V3.80.00 This is a new project and all equipment is latest spec. Although I have communicated with the PLC and down-loaded the PLC ladder logic, I cannot download the panelbuilder program. The RS linx 'see's' the PLC but not the Panelview. I have also tried connecting the panel view directly to my PC serial port and tried using DF1 etc to communicate with it, but still cannot down load the panelbuilder program. I assume that I am not configuring the Comms correctly, and would appreciate some help and guidance on this. Regards, mrbj

What is the part number of your Panelview?

[Ken Roach 194]

Post the exact part number 2711-xxxx of the PanelView. That will determine which serial protocol driver in RSLinx you'll use. Remember also that the serial cable between the PanelView and the computer needs to be a straight-through cable. This is different from the serial cable between the SLC-5/03 serial port and a computer, which needs to be a null-modem (swap pins 2 and 3) cable.

Hi, TWControls & Ken Roach. Thanks for your response. I have being back to site to check on a few things. The type of panel view is 2711 - T5A5L-1, Ser B, Rev E, FRN 4.46 and powered by 24V dc. The dc connections are correct. The cable between the PV550 and the SLC 5/03 is a 2711 - NC13, which as far as I am aware is the correct one. There is only one RS232 port on the back of the PV550. I can connect my PC via its serial port to the PV550 directly using a 2706-NC13 cable, which is the cable I use on other PV's. When I do this there is still no response. In actual fact the PV appears dead, even with power on and pressing the reset button (located at the back under the mem card slot). No info / menu etc appears on the PV screen at all. Am I missing something obvious?? PS.. the one thing that I was hoping to do was to connect the PC to the SLC via the 1747-PIC and have access to both the SLC 5/03 and the PV550 whilst it (PV550) is connected to the SLC5/03 using the above 2711-NC13 cable. Is this possible ?? Regards. mrbj

As Mickey has pointed out, the 2711-T5A5 PanelView 550 terminal has only one port, which is electrically RS232 and uses DH485 protocol. This means you use that 2706-NC13 cable (or any other straight-through cable) and use the 1747-PIC/AIC+ driver in RSLinx. I agree that if nothing shows up on the PanelView screen when you apply power that you have a defective terminal. The backlight should at least power up. The SLC family supports a few carefully-configured port-to-port passthrough functions, but DH485 to DH485 on an SLC-5/03 is not one of them. You probably won't be able to configure this terminal, which sounds brand new, with version 3.80 of PanelBuilder32. There have been two releases (3.81 and 3.82) that add firmware support for the newest terminals over the past 3 or 4 years.

Hi, Thanks to Mickey and KenRoach for your replies and advice. The PV550T is faulty and I've arranged to send it back. To replace it I've ordered a 2711-T5A16L1 with DF1 and a printer port. Now, as far as I understand it... I should be able to connect the SLC5/03 with a 2711-NC13 cable to the PV550T. Also connect my PC to the PV550T with 2706-NC13. And have everything running on DF1. I would set .. The SLC5/03 channel 0 to DF1 // Baud=9600 // Node=1d //Parity/stop bit = None/1 //Error=CRC // Handshake=off . The PV550T to the same , except Node = 2. In the PV550T I would set the Printer port (RS232)9pin to "download". Have I got this right, will it work, and will I be able to see the SLC5/03 via the PV550T and be able to modify/upload/download/go-online etc the SLC5/03. I would appreciate your valued comments and advice on the above. Regards, mrbj

Actually, that was the wrong choice. The printer port can only be used for printing or for downloading to the PanelView terminal. It is not a "DF1 Passthrough" port to the other communications port. If you wanted simultaneous communication with both the SLC-5/03 and the 2711-T5A5 terminal, you should have connected them both to a 1761-NET-AIC isolator/converter module. Connect the PanelView to the 1761-NET-AIC with an RS232 serial cable (2706-NC13) Connect your PC to the 1761-NET-AIC with an RS232 serial cable (1761-CBL-PM02) Connect your SLC-5/03 Channel 1 to the 1761-NET-AIC with a 1761-CBL-AS03 cable. Illustrations of this kind of small network are provided in the 1761-NET-AIC installation instruction booklet. Using the 1747-PIC/AIC+ driver in RSLinx, you would then be able to connect to the SLC controller and the PanelView terminal from your computer.

Hi, Thanks Kenroach for your advise/help. Apologies for not replying sooner. The PV550T with serial (DF1) comms was used in the end. I used the PV550T printer port for downloading to the PV. Not a bad thing, since it allowed me to keep the cable from the PV to the PLC in place, and the cables from the PV to PC and PLC to PC (via PIC) also in place, just had to swap at the PCs' serial port, change driver in rslinx etc when required. The plant is now up and running. Incidently, my old panelbuilder software V3.80.00 works ok with the PV550T c/w new firmware, some features may not be available, but nothing flagged up. Just a quick question, why would you have preferred to have stayed with the DH485 comms as against the DF1. ?? Regards
