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

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

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

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

Hi, I am having some difficulty with the following, any input is gratefully received. System AB SLC 5/03. 1746 - HSCE Card for encoder 1024ppr encoder input. 1746 - N104V 2channel analogue input/output card. Drive roller dia = 100mm (~4inch) The encoder is mounted on the motor shaft. The motor - gearbox ratio is 1400rpm - 60rpm The machine drive roller pulls material through the machine at about 10m/min Q1 What happens when the encoder reaches its roll over value of 32767? Q2 I need to measure the speed of the machine via the encoder and send a 0-10V output to another drive card via the analogue output card. I assume I will have to convert ppr to rpm and then to a value that the analogue card can use for the 0-10volt output. Q3 I also need to measure the amount of material passing through the machine. I would appreciate any help / suggestions on how to achieve the above. Regards, mrbj

Hi, I have just read some of the posts regarding the above counter module, and although I have programmed plc's over a number of years, all be it pretty basic stuff, I think I am setting myself up for a fall. On site there is a SLC 5/02 plc (1996), with spare slots. I am using RS logix 500 V5.20 software. I know its a bit old but it works. I have been asked to add the 1746HSCE card and connect an AB 845 diff encoder. This is to measure the distance between products coming down the line. The current system is inaccurate. All I want to do is measure a number of pulses, send an internal flag to initiate an output, then reset and start all over again. This may sound pretty simple stuff to you guys, but hey we all live and learn. I would be grateful if someone could put together a ladder that would do the above, and include any other set up information that I may need. Any help is gratefully received. Regards, mrbj
