  1. Lamp Bit and Buzzer

    The CP1L series PLC's do NOT support bit level addressing of D registers. [Only available in CJ2M series] So change the allocation addresses to W memory. Turning on W0.12 in the PLC will turn on the continuous buzzer on the NS15 HMI.
  2. Lamp Bit and Buzzer

    Then you need to change your communications setup in CX-Designer by adding a HOST to the ethernet option and then point the NS memory to the desired location in the PLC.  
  3. Lamp Bit and Buzzer

    In CX-Designer go to PT->System Settings ->Initial. Assign "$SB Allocation Address" to the PLC memory area you wish to use. Then select "System Memory List". In order for communication to work you must enable the check box.  
  4. High speed counter

    There are only two high speed counters available for each MD211 module. Right hand MD211 uses counters 0 and 1, left hand MD211 uses counters 2 and 3. To read the present value for each counter the Port Specifier of the PRV(881) instruction is #0010, #0011, #0012 and #0013 and the Control Data is #0000. You must configure the type of counter in the PLC Setup, then download the setup to the PLC. THEN MOST IMPORTANTLY POWER CYCLE THE PLC FOR THE NEW SETTINGS TO TAKE EFFECT. Attached is link for MD211 module manual. See Section 7 for details on high-speed counters and 2-3-3 for PLC Setup https://assets.omron.eu/downloads/manual/en/v3/w486_cj2m-md21_pulse_i_o_module_users_manual_en.pdf
  5. Controlling heater element with PWM

    That code only addresses PWM Output 0 at 200Hz with a 50% or 25% duty cycle. Physical output is 2961.4 = Output 4 on the right hand MD211 [Closest to PLC]. "I don't see anything! Or where I can see this pwm signal? " THIS WILL NOT WORK IF YOU ARE USING SIMULATION MODE IN CX PROGRAMMER OR IF YOU ARE USING 2961.4 AS AN OUTPUT ANYWHERE IN YOUR PROGRAM. You must have physical PLC and MD211 with downloaded program to "SEE SOMETHING"!
  6. Controlling heater element with PWM

    PWM can only be used for outputs of MD211/212 Pulse I/O module. Not possible with OD212. You say "I read in documentation about Pwm but is a poor explication about this problem." What documentation are you using? It is very clearly explained in the Instruction Reference Manual W474 and Pulse I/O manual W486. Do you have these? Here are links:- https://assets.omron.eu/downloads/manual/en/v3/w486_cj2m-md21_pulse_i_o_module_users_manual_en.pdf https://assets.omron.eu/downloads/manual/en/v3/w474_cs_cj2_nsj-series_plc,_sysmac_one_nsj_series_reference_manual_en.pdf    
  7. Read position from rotary encoder

    Port Specifier should be #10, #11, #12 and #13. Control Data should be #0 in all cases.
  8. APR - OUTPUT VALUE

    The example I posted works correctly for the values you are asking for.
  9. APR - OUTPUT VALUE

      CP1L_APR_SCALING.cxp
  10. APR - OUTPUT VALUE

    This example for a CP1L might help you. http://forums.mrplc.com/index.php?/topic/30950-proble-with-scale-function-in-cp1l/#comment-145675
  11. Cx Integrator

    Simplest method! Don't need CX Integrator. http://forums.mrplc.com/index.php?/topic/36339-send-data-memory-from-plc-to-other-plc-with-cx-programmer/#comment-169499
  12. how to set up timer in st

    What is the model number of the PLC you are using? CJ2M, CP1L, CP1E............................ Structured Text timers or Counters can ONLY be used with CS/CJ series CPU units version 4.0 or later, or with CJ2-Series CPU units.
  13. Send data memory from PLC to other PLC with CX Programmer

    If you are using Serial Communications between the PLC's I would use PLC Serial Links for such a small amount of exchanged data. Requires NO programming in PLC! Attached extract is for CJ2M PLC but available in most OMRON models. Serial PLC Links.pdf
  14. Thanks for quick response and app. note. Connection via Serial as gtsupport mentions works just fine. But I really prefer to go with Ethernet if I can get it working. Attached are extracted pages from IDEC manual showing that the HMI "should" be capable of connecting directly to the PLC. Setup procedure in IDEC WindOI-NV4 is somewhat confusing and missing anything regarding the need to use CX-Integrator as IO_Rack mentions. Have contacted IDEC Tech. Support and await reply. Meanwhile I'll continue working with "Good Ole Serial" Idec Specs 2.pdf Idec Specs 1.pdf Idec Specs.pdf
  15. I am struggling to establish Ethernet communications between an IDEC HMI and OMRON PLC. Can ping both devices on the network, BUT HMI shows a communication error "ID:00h 0". Anyone have any suggestions how to resolve? Do I need to use CX-Configurator to setup a routing table, and if YES how to do it?   Frustrated/Confused.
