  1. ML1000 MSG Instruction

    I have attached Screen Shots of the Communication Set-up ML Channel 0.bmp

  3. ML1000 MSG Instruction

    Serial Communications L32E REv 20.19 DF1 Radio Modem      
  4. ML1000 MSG Instruction

    The master controller is a ML1100 Series B.  The controller it is having trouble communicating to a Compct Logix L5332E .  I am not doing error tracking yet but I would guess I am getting 1 out of every 3 successfully.  All the other controllers are communicating with are ML1100.   I just seems odd that I am getting messages through  so my config should be ok.   I have dropped the time out from 5 to 1 in the MSG instruction and my poll is better but that's just because the timeouts are finishing sooner.  I am only reading 20 registers per instructions.
  5. ML1000 MSG Instruction

    I have a SCADA system communication over serial radios and to one of my site I am getting a Error Message in my MSG Instruction "Hex 37" MSG timeout in local Processor".  The odd thing is i have communication with this site.  I am only running one message at a time and cascading through the messages.  Some of the messages do get through. My message time out is set to 5 and am having this issue with three messages to the same PLC.  So it is slowing my system down.
  6. Configure MicroLogix 1100 with 1747-UIC

    Once you are connected to the PLC  in RS Logix got to channel configuration of your controller make sure you i/p address is there. Under Protocol Control and uncheck BOOTP Enable and DHCP Enable. Make sure you I/P address is set.        
  7. The logic scans top to bottom and left to right.  The 11 columns is the most you can go in modicon ladder logic.  If you need more you can go down to the next network and continue. but you have to repeat the register you are working with. Not sure if this helps.
  8. Modbus TCP Enable

    I have an application with a ML1100 Controller which I a trying to communicate to a Kohler Generator.  The generator Talks Modbus TCP and there is a Prosoft Gateway PLC32-EIP-MBTCP.  This gateway will convert my information to Ethernet I/P but it will be in a 4x register format.  Is there a way in the ML1100 to enable Modbus TCP like the ML1400?  or can I read this with a MSG instruction.  Thanks
  9. I am looking for a solution to connect a PC to a modbus plus network for my HMI.  The old option was to use an SA85 card but is there something better.  Ideally ethernet I/P to Modbus Plus Converter if there is such a thing.  Does anyone have a recommendation that they have used.  
  10. Compact Logix Ladder

    Thanks  I ended up doing a similar network in Ladder to get what I needed.  I agree that they should have kept the SCP in ladder.
  11. Compact Logix Ladder

    Is there a simple instruction where I can fill in a table and do a look-up based on a value.  I have a airflow meter that Pressure correlates to Airflow but it is non linear.  I have 11 pressures that equal 11 flows. Using RSLogix 5000 V20.04 Ladder logic only, no language pack. Thanks  
  12. Compact Logix

    Thanks, I have decided to use a 1769-L32E at the remote site which has a built in Serial port.

    Unfortunately we have to stick to the serial radio's for now.  The plan is to go to Ethernet radios in the future but it is not in the budget for this year.  There are 10 remote sites. 
  14. Compact Logix

    I do not have Ethernet between the two plc's. They are miles apart and we utilize serial liscense frequency radios to communicate. 
  15. Compact Logix

    I have a control system based on Micrologix 1100's  (one master and multiple slaves) I would like to add a new PLC to the network.  Can I use a 1769-L32E or similar in the field and connect its RS-232 port to a serial radio (this would be a network slave).  I want to use the Micrologix 1100  with a message instruction to read the PLC.   The reason I want to do  this is to migrate the system to a new platform in the future or  should I just add another ML100 to the network and continue on the same path. Thanks
