  1. I’m using a Omron NJ to manage a LinMot linear motor .. all is going very well; however, there have been a few times during this development phase when the actuator, or programming creates a fault, perhaps from a following error, or exceeding a limit.  The result is sometimes scary.  The actuator might accelerate into a hard stop.  Not a big deal, the ends are protected with Sorbothane, so it isn’t a big problem .. yet.  Once the system is correctly programmed, it shouldn’t ever accelerate an actuator into the hard stops. In spite of my newbie-ness  to Omron programming I’m aware of the need to employ error & fault action that will stop a run-away actuator in closed-loop control, rather quickly. Just how to do that.. has evaded my research. I’ve noticed:  “FaultHandler”  in the W507 & W508 Manuals. And, been quite frustrated to not find any reference to FaultHandler or FaultHandeler()  .. which kinda suggests it’s a program?… and also expected to get some clues in the "NJ Programming Best Practices V1.1”   so far… no luck. Perhaps I’m going about this all wrong..  The LinMot Driver Controller might be the way to go.. An error message from the NJ to the LinMot drive would quickly shut down movement in closed loop .. instead of turning the motor into a rail gun… Any suggestions at how to do it with the NJ,  would be greatly appreciated.. Thanks Regards, Michael PS: here’s the progress so far, thanks to many out there, and on this forum ...  
  2. Urgent help CS1 CPU Stop

    Hello all, Require some urgent help on a project, apologies if poor explanation.... When CS1 CPU goes into stop mode in fault condition, eg fatal cycle time error, outputs retain in the state they were when CPU was stopped. In code we monitor CPU status and turn output high to pull in relay to indicate CPU status normal to wiring circuit. But if CPU goes into stop mode relay remains energise as code is not running to turn output off?? Therfore for examples conveyors keep running... How can we prevent this, can outputs be configured to go low if cpu stops? Any other ideas? Any help will be appreciate, thanks.
  3. For some background information, I am in the process of converting a Mitsubishi FX2N to a Siemens S7-1200. I am viewing the Mitsubishi program with GX Developer Version 8.116W. There is this subroutine in the Mitsubishi program that appears like it will never run. I think the purpose of this subroutine is to clear the status of the devices in the PLC. I have attached a picture that demonstrates what I am dealing with. Can anyone tell if the subroutine P7 will run at any point? Thanks! For those who are not used to the Mitsubishi world or want to brush up on their Mitsubishi knowledge, below is some information regarding the devices and functions used in my example: M8000 - Always on bit (turns on when PLC is running and turns off when PLC is stopped). M500 - Just some random memory bit I chose. FEND - Indicates end of main routine program (everything below this rung is either a subroutine or interrupt routine, so it will only be processed if called from somewhere). P7 on left side of power rail - This is a label that indicates the beginning of the subroutine called P7. M8031 and M8032 - Special memory bits that, when set, tells the PLC to clear certain devices. SRET - Indicates end of subroutine.
  4. Hi, in my proyect i need integrate 2 modes, Auto abd Manual, but i have a doubt if i can use GEMMA (run/stop modes guide) I don't now if the software integrate this functions or I need integrate a subgrafcet (each mode need one) Thanks
  5. Auto Run Mode after Reboot

    Hi guys! Im new in using PLC and im using CPM1A, is there a way setup the plc to run mode immediately after rebooting it, also even without connecting it to PC or handheld device? I saw in the manual "Startup Operating Module" but i am lost, i dont know how to configure it. Thanks for your advice.
  6. Dear colleagues and siemens experts, I''m new in siemens. As all I make my program for PLC, but I need help with PID autotunig (pretuning) I use : 1.CPU 1214C DC/DC/DC (6ES7214-1AG40-0XB0) 2. 6ES7214-1AG40-0XB02. 16IN/16 OUT DC/DC/DC (6ES7-223-1BL32-0XB0) 3. 2x 6ES7231-5PD32-0XB0 ( 4 channel RTD analog module - PT100) We use 7(seven) Pt100 points with 7(seven) heaters ... so I need 7 additional outputs..... [you can see example of wiring in attached pic 6es7231-5pd32-0xb0-modules.jpg] Maximum heating point is around 220 degrees. I make my configuration for PID_Compact : 1. Basic settings 1.1 Controller type : Temperature : °C Set mode to : Pretuning ( sometimes I make it Automatic mode) 1.2 Input_Per(analog) -----> Output_PWM 2.Process value setting: 2.1 Process value limits: Process value high limit : 220.0 °C 2.2 Process value limits: Default 3. Advance setting 3.1Process value monitor : Default 3.2 PWM limits Minimum ON time : 0.5 sec Minimum OFF time : 0.5 sec 3.3 Output value : Default 3.4 PID parameters : Default I start Commissioning with these steps : 1. Measurement : Sampling time 0.5 Start 2. Start PID_Compact 3.Tuning mode : Start When I try first time my setpoint was 90 degrees , second time I try with 120 degrees. After 4-5 hours it stop more in Progress bar it stop when I reach a little more then 50%, and I stop PID. For heaters it is not normal to process to be 4-5 hours, there have some wrong. Example with 120 degrees : During process I make : When Input_PER reach 120[1200] degrees I stop physical access to heaters. When Input_PER reach 100[1000] degrees I start physical access to heaters So 4-5 hours is soo long time for this type process. Time to reach 120 degrees from 100 degrees is around 2-3 min. Time to fall from 120 degrees to 100 degrees is around 4-5 min. Total time for one whole cycle around : 8min. Sometimes when I set setpoint to 140, 150 degrees it writes me that output set value is to high after I give Start Pretuning ? Even sometimes when try for 120 degrees .... As all I want to start PID pretuning (autotuning) with setpoint 140 - 150 degrees. Which are minimum requirement to start PID autotuning with PID_Compact ? Could you send me some very simple example and steps that I must make or only steps ? I attached files in dropbox with images and program example, because I can't attached nothing here. This form don't give me access to attached something. So link is here : Even program is there. Thanks in advance Best regards : Altan
  7. Hi everybody I'm new here. Can someone please help me? I have a normal single phase traffic light that works fine but, i need it to start and stop with only one input? Any ideas?
