  1. PC to SLC5 using DH485 protocol

    Thank you for allowing me post here. I have a PLC SLC5/04, I usually connect to PC using DF1 (RS232 port). But recently, I had to use DH485 to connect to a new touchscreen.  Now, After setting RS232 port to DH485( In Channel Configuration/Channel 0-System). I couldn't connect to PC using RS232 port. In RS Linx, I tried both "DH485 UIC devices" driver  and "RS-232 DF1 devices" driver, but the PC couldn't recognize SLC5/04. Did I do something wrong?  
  2. Hi All I am new here without much experience of plcs. I have a PV 550 with DH485 coms port that I want to replace another PV550 with rs232 that communicated with an SLC 5/04. Is there some way to connect the two with a cable or protocol connector? Alternatively can you connect through the printer port on a PV600? CHeers   Azza
  3. Hello experts, There's an existing PanelView600 (2711-K6C5 which has only RS-232-DH485 communication port) communicating to a MicroLogix 1500 (it seem to be an LRP processor since the serial communication is connected on the CPU left side) via female-female 9pins ribbon cable (used all 9 wires that I tested just straight-connect). Now my questions: 1) I read that I can upload PV600 project direct to laptop w/serial port using also straight connect 9pins cable (using just pins 2,3 and 5) and 1747 PIC/AIC+ driver on RSLinx. Could I just use the 9pin straight ribbon cable (using all 9pins) currently used by the PV comm. to ML1500 (unplug port to ML1500 then plug to laptop serial)? 2) Could I also use this same cable to upload ML1500 program (unplug PV600 port then plug to laptop serial)? 3) The new PanelView Plus 600 is a 2711P-K7C4A8. Could this new one also used that old same ribbon straight cable? I checked that this PV+ basic RS-232 port could also handle DH485 protocol and I also checked on a manual named "Legacy PanelView to PanelView Plus 6 Catalog Number Conversion" that it seems it's the particularly the correct counterpart of the old PV600, which also particularly emphasize the comm. port (RS-232-DH485). That's exactly what this is supposed to mean right, namely that the 2 panels have similar communication port, hence no need to modify anything on communication (esp. hardware/cable) right? I'm worrying because the plant guys said that those previous conversion, the other guys wasn't able to use the same ribbon 9pins straight cable from ML1500 side port to new PV+, instead they had to use the round port of the ML1500 and then used cable with some converters along the way before reaching the PV+. What do you think? Any inputs would really be appreciated!
  4. change port setting

    Hi, I have PLC slc500 /3, connected with panelview 550 DH485 I have to replace the panel view by another available one which is different in part number my old one is 2711-B5A2 the new is 27711-B5A5 communication port for the new is 9 pin RS232 (DH485) when i read manual for panel view it mentioned that if i want just point to point (it is my case) i can change port configuration for the lower port of PLC to be DH485 and use cable 9 pin from 2 side first I don't know how to change port setting, if i change it how i connect to modify or troubleshoot the plc later? could i make a cable form the above port (RJ45) of PLC which is used for old panel and configured to DH485 to the new port 9 pin RS232? why when i order a panel view should mention the "ser" by the way it is Ser H??? When I try to buy new one , I didn’t find Panel view (obsolete ) gust find panel plus is it direct replacement for panel view or I need to rebuild the application program from beginning?
