  1. Siemens plc system

    I have just been informed today that United Utilities ( North West Water) are changing there framework Supplier for PLC hardware from Allan Bradley to Siemens. Has anyone had any good / bad experiences with siemens PLC either on Hardware or Software Best Regards Chris Bramall
  2. Programing Cable

    Alternativly you can use the standard CPU Mounting 3G2A6-LK201-EV1 which can be used for C120/C200H/C500/C1000/C2000. however if memory serves me right for the C200H there is a funky metal extension plate to allow the CPU connector to link onto the processor. Used one years ago but can't remember what the part number is. If this would be of use I can check on Monday as it's still in my box of misc programming bits. Regards Chris
  3. C2000H to CS1 RS422 Communications

    Well i'm glad to report success. it appears that the CX-Protocol now ships with a protocol set to allow communication to C series PLC's. The protocols are also now being shipped in the latest issue of the protocol macro card. After some tech help from Omron UK, got the system up and running. Transfering 108 Words of CIO data, 450 Words of DM data. Typically a 15 second scan cycle to transfer the data. Regards Chris
  4. C2000H to CS1 RS422 Communications

    Hi, I'm hoping someone can help, I'm trying to read information from Data Memory in a C2000H PLC to a CS1 plc over a RS422 communications link The C2000H is fitted with a 3G2A6-LK0202-EV1 RS422 card the CS1 is fitted with a CS1W-SCB41-v1 Serial Board, RS232 / RS422. Anyone any ideas. or help
  5. CS1 I/O Address Mapping

    I've just re read your post and realised i've gone off on the wrong tack. really all your trying to do is swap the I/O addresses of card 1 & card 2 over. Just swaping the card positions on the rack and updating the I/O table will achieve this.
  6. CS1 I/O Address Mapping

    There are possibilities The first is the most expensive, move all the cards up one position and put a spare unused CIO I/O card in the first slot this will force all the CIO units up one. the 2nd i've never tried but it might work. within the I/O table for CS1 plc's there is the option for a dummy I/O selection again move the I/O cards up one and leave the I/O Slot 0 empty. within the I/O table select a dummy I/O module for the first slot. this will again move the I/O addresses up one.
  7. I've got a Compaq NX9005 which does have a real RS232 port and works fine with the 1747-PIC. You have to let the system install the specific PIC serial driver. Chris
  8. C2000H to CS1 RS422 Communications

    Hi Jay, thanks for the help, Things have been really slow from the PLC side, so i've been off doing other things. All these PLC software frameworks flying around really restrict the smaller private company from developing skills and undertaking projects. So we tend only to pick up the difficult or unusual that others won't even look at. Regards Chris
  9. C500 plc up for grabs

    As I was saying over in the "Other PLC" section i've got an old Omron C500 plc which was removed by us during a customer upgrade around 5 years ago. The PLC is complete with one of the old style programmer pads with a tape recorder input. I'll post a photo and some I/O details on monday. Don't forget this PLC is currently in Barnsley , UK and whoever want's it will either have to collect or pay the shipping costs, sorry  but i.m not made of money and it is quite heavy
  10. Modbus configuration

    Does anyone know how to configure a CP341 Part No. 6es7-341-1ch010AE0 from RS422 two wire to RS485 4 wire, the spec says it's possible but I can't find how to do it.
  11. RS-232 40meters?

    In my young and foolish days I installed a RS232 link between at C2000H LK203 card running at 19.2k to a NT600M. The RS232 was transmitted down a 5 pair 0.75 BS5308 screened cable to various plug points where the NT600M could be connected. Worked fine out to about 40metres which was the furthest point on the system. must have been lucky or maybe the increase in the cable size helped. Regards Chris
  12. Siemens plc system

    Well i've just upgraded to the V5.2 of the software and alot of the gripes of things that were missing from changing from RSLogix have been sorted, we'll have to see how it pans outin the long term.
  13. SATCON 05 & DOX 05

    I'm doing a project where we have to tweak a SATCON 05 PLC. I've got DOX 5 Version 4 software but there's no manuals or help files as it's been sat in a draw for the last 10 years. Does anybody have anything that might help to get me out of this hole i'm in.

  17. We didn't have too many problems but keep a rolling check on the data stream using a time output transmitted from one PLC to the other and back again. If either PLC did not see a change for a set number of seconds the system was configured to shut the process down until the communications was reestablished. The radio system used was an RDT unit with a range of 10km but we were working at approx 0.5 km so we could dial the power level down a bit, and we could selected a free frequency. I havn't come accross the spread spectrum units but they sound pretty could from kens description.
  18. Hi as detailed in one of the other threads I have linked two SLC5/03 PLC's together using two external RDT radio modems acting as a DF1 node to node gateway using the msg command to read and write data. The link updates about once every two seconds at a baud rate of 19200. Is this any help ?
  19. Which Allen Bradley SLC500 processor is being used. Without this information its pure guess work as the different processors use a variety of leads, convertors and protocols.
  20. Panelview poll

    It Wasn't intended to be a fair poll but was just to answer my own curiosity. I'd been working with a variety of Panelviews and wondered what other peoples preference was .
  21. Out of all the panelviews you have used which do you prefer
  22. C500 plc up for grabs

    To the formum member that sent me a message via the MRPLC site regarding this PLC can you please contact me again with a valid email address as the previous one kept getting rejected. Please remember the PLC is in Yorkshire, second hand and i'd envisage that it would only be any could for college/traiing/demonsatration work. If anyone is interested send me your details and i'll calculate how much it would cost you for delivery. Regards Chris Bramall
  23. Definitiion of a plc

    We use the ABB Commander 350 series controller to act as a small PLC for duty standby pumping stations. The unit uses logic statements and maths statements which are configuarable as well as the more traditional PID routines. We have also used the Eurotherm T640 which has a simalar setup. So what are they PLC's or PID's
  24. Mitsubishi melsec plc inop

    Out of interest has the unit got a ram card fitted and has the power recently been switched off for any reason. It could be something as simple as having no program in memory due to a flat memory backup battery ?
  25. Why try and figure out the command conversions and give your self a headache , if you know what the PLC is going  to do then make the most of the new PLC be use of a structured programming approach and rewrite the software to match the new hardware.
