I am desperately trying to understand the OMRON way of programming (28 yr. AB programmer) when it comes to Motion Control.  I am pouring over example programs and what I can understand in Omron manuals.....  What I cannot find is where you get all the bit level information from for individual axis....  For example, just a simple bit signaling a Servo Fault; I have a program that I have been studying and there is a bit with the variable MC_NailPunch_Station.MFaultLvl.Active, it obviously comes from the Axis "MC_NailPunch_Station", but I cannot find the reset of that variable anywhere in the program, in any setup....nothing. Is there a list somewhere of things like this I can use in my program for status bits etc.?   Thanks,

Hi all,    I have an FB (ST) which will calculate the UINT values that need to send to DA outputs. Currently i was requested to add a delay between the calculated output & DA units. I am not sure how to do it? can I just use a TON? Any sample ST code?  

Dear all, In a state machine I have certain states which need to have a timer to handle timeout errors, that is, if the FSM remains too long in a certain state without getting the conditions to transition to another one, it will produce an error. My current code is using a TOF with an input variable that will be triggered upon entering the state, I call the function block, and then turn the signal off so it starts counting: TRIG_STOP_TIMEOUT := TRUE; TTO_GLOBAL_CYCLE_STOP(IN:= TRIG_STOP_TIMEOUT ,PT:= T#15s ,Q=> ERR_GLOBAL_STOP_TIMEOUT ,ET=> CLK_GLOBAL_CYCLE_STOP ); // TOF TRIG_STOP_TIMEOUT := FALSE; For some reason, the counter does not work. I don't know if I should trigger the signal on in one scan and off on the next. I thought about using the system 1s clock as a trigger (SM412) but the description of the TOF function block states whenever the input is ON, the output will be true, and the timer will only start counting once the input is low. The other thing I thought about was to use the TOF_E instead, with the clock as a trigger, and just set the enable signal when I'm in the state, but I'm not sure it'd work correctly, either. Any suggestions?

Hi experts, please share the sample blocks for the EDITABLE TIMER block it should be editable from HMI(Siemens). And also motor run hour block. Actually i am having all blocks in tia v12 version and sadly i dont have the old software to convert it again. So please share the blocks that it shoud be work in TIA V14 for s7 1200 plc's. Please note that the blocks should use add instructions to calculate the time because i don't have much memory.

Hi,   I'm pretty new to allen Bradley and wanted to know if there was a function that could help me out. I have a rotation sensor which feeds back to the PLC via a digital input, once every half second or second once machine is up to speed - I want to record the off time of this DI (how long it is off between pulses, essentially how long it takes for drum to rotate once). Is there some way to record this time and use this value for compare logic? any help would be greatly appreciated.   PLC: Micrologix 1400 series B RSLogix 500 version 11.00.00 (CPR 9)

Hi all, I would like to ask you about the name and manual of the command protocol for PLC Siemens.  I am not asking about communication protocols, I am asking about the protocol of the commands to use some features of the PLC without TIA Portal. In a similar way, OMRON is using the protocols FINS and Hostlink, or Mitsubishi is using MELSEC commands. Thank you very much.

Sorry first up for what may seem like a simple post / question, however I am pulling my hair out with reading the programming manual and have had no help from Mitsubishi's PLC technical support team.   I have a Mitsubishi Alpha 2 (AL2-10MR-A) that I am using to count the starts of a jacking pump via input one. The intention is to have output one operate when the jacking pump start count reaches 5 within a 24 hour period. When the 24 hour period has expired, the count will reset to zero. The count will also reset to zero when a manual keypad key is pressed. I have been able to figure out the counting and reset via the keypad no bother, however, including the 24 hour clock reset is proving difficult. Has anyone had any experience with adding the 24 clock function at all, and can offer advice or examples? This is being programmed directly via the keypad.   TIA

Hi Everyone, Sometimes I forget to cancel forced bits in omron CJ2M-CPU34 PLC. I want to cancel all forced bits automatically and found something about fins command. I'm now facing difficulty in activating the all cancel forced bits command. (2302) Is there anybody know how to use @CMND command for cancel forced bits?  Thank you.  

Hi guys,     I am trying to make a controller for an oven using MODBUS with a CP1L and an NB screen. My oven program will have 10 stages in one baking cycle, and the parameters for each stage can be modified individually (temperature, blower speed and time). I have set my number input in the NB screen to be a unsigned int of 2 integers and 2 decimals, and it writes to H4 in plc H memory. I move this value from H4 to W4 in the PLC, and input W4 into a timer (T0000). I have tried data manipulation and still have no success in getting this to work properly. My CP1L timer is set to BCD mode, as I am using premade MODBUS function blocks which are programmed with timers in BCD mode. Does anyone have any pointers regarding this? In the screenshot provided, the number i inputed in the HMI was 60.00.

Hi all, I have communicated my tp1500 with Ab 1400 B series..the proble is I have setted setpoint of timer is 30min Accum...so I read my timer pv in hmi in that time ##will shows in hmi in that case I cross checked my program its twr running properly.   Another how to set date for tp 1500

Hello, I want to count rotation time or cycle. I am using bellow code in the picture. If I set timer 10 ms, when counter working well, but I set timer 1 ms the counter working same how set timer 10 ms. I have question in my code is slow timer or counter and somebody give me advice how need count the rotation ms accuracy.    

I am using CJ2M PLC.I want switch on a output for certain time by a timer and holding bit if interlocks satisfied.If interlock not OK timer has to hold the time and output should be off. if again interlocks OK again output has to ON upto balance time completion and has to give timer done output for reset holding bit.please suggest.

Hi, I am trying to do a merge move on 1S Servo. The condition are as follows: Task: Move 2 in(absolute value) and then Move back to 1 in (absolute value). I have to do this move 10 times in a row.  The application is material leveling after dumping in the mold. The only question i have is if I use just MC_MoveAbsolute command, the only buffer mode for transition available is velocity. Is there a way i can do it with position. I dont want to stop when I can go from 1 to 2 and 2 to 1 again and again. Its time consuming. But rather a nice oscillation motion without stopping to mimic leveling. Can anybody please help me out with this problem.   Thanks

Hi Guys! I have a problem with Motion axis move (MAM) command. There is an Allen bradley servo motor what is working well. But I need to add a new program section, wich is in  a specified moment, the axis should move a certain distance. I think I need to use the mam command, just I dont know how can I configure the motion control part. I need to make a new tag ? or what ? I need to use a user define ? PLS help me.   

Hi all, I try to realize a cycle timer. A counter is triggered by a movement ( clamp close ) Then the machine does it things, piston here, and there and when the clamp closes again it should show me the real cycle time. Is there a timer/counter that is independent from the PLC cycle? I am using a CJ1M CPU11 Ver. 3.0

Hi every body! Now I use a Q-motion controller Q172DSCPU with advanced synchronous control method. I try to synchronize 4 axes with Axis1 as command generation axis. The problem is that the command generation axis current value is not be cleared to zero after restarting the cycle. It should be cleared to zero to be kept within stroke limit during the process. Thanks in advanced  

hi every one! i'm new with PLC mitsubishi, i have a Fx3u board and using Gx developer i can config input interrupt pointer in GX developer  but i don't know how to config timer interrupt with GX developer. i have read a lot of manual but i don't understand... someone can help me?????  

Hello everyone! Could someone help me and tell me what the "D212" means? I know that to define the time of a TIMER you must put a k and number (miliseg).   Help.... :(

Hi I put value #80 in word 60 I run timer 2 with word 60 I replace word 60 withe the value #10 I run timer 2 again with word 60                       but you see the timer counting down from 80 instead of 10 So the timer runs first the previous value of word 60 before he runs with the new value although you see the new value of word 60 appearing in the timer. How can I let the timer run immedeatly with the new value.   Thank you

I tried setting parameter in gx works 2 for plc q series of q03ude cpu. I set retentive timer to 1k and reducing special link relay to 1k from 2k. then I set 0 in latch 1 start and 5 in latch 1 end. Getting error c4129 and c4139. I changed it to just 16 points of device, then put 0 in latch 1 start and 15 in latch 1 end, still getting same error code. In mitsi pdf of basic course, it just said all I have to do is to go to parameter>device>set retentive timer value to 32 from 0 to use 32 timers total, but I just simply getting error code of f1028 How to make it right? Got it now, have to uncheck retentive timer in tools menu.

Didnt know this before but should have anticipated it, I cant put 8 hours into say a TON or a TOF, etc. Only goes up to 2880 seconds, .8 of an hour. What would be the best way to go about this?

Hi, everyone, I started learning very recently, and I have been writing this little program in which I communicate through RS-232 with a machine. Every time I send a command from the PLC I wait a couple milliseconds for the machine to send a response (a response must always exist, even if it's a mere acknowledgement response), then I save the response that the machine has sent. I organized my ladder logic by the commands that the PLC has to send to the machine (4 commands total, for example: execute this, give me status on that, etc). I started every ladder with an OSR and an AWA instruction, and when AWA is done I have a timer in the next rung to wait for the machine response, and after timer I have a ABL activated when TON is done. The Ladders are related in the sense that the end of each LAD contains a JSR instruction to the next command/ladder. So the commands/ladder always execute in a predefined sequence (LAD2 -> LAD3 -> LAD4 -> LAD5). The logic inside each ladder is like this (the last rung is a little different for the others, this is LAD2): ] start [ ----------------------------------------- [ OSR ] ] OSR OUTPUT BIT [ -------------------- [ AWA ] ] AWA/DN [ ---------------------------------- [ TON ] ] TON/DN [ ----------------------------------- [ ABL ] ] ABL/FD [ ------------------------------------ [ ARL ] ] test if ARL string is 0 [ ----------------[ JSR ] 1) Since I have to use timers so often in my program (they all last for the same period of time) I wonder if I could use the same timer every time (same Control File R6). But I'm quite lost on WHEN I would have to reset the timer, or if this would not be recommended at all, since the timer is still counting for more than one scan. Although I want to believe that the timer for that Ladder would never be counting after the JSR instruction, I think this is true only for the first time since the next time I turn "start" ON the ARL is not zero, so JSR would occur while the timer is still counting. I tried resetting my timer parallel to JSR and using the same timer in the next ladder, but then the timer only counted up for the first time "start" goes ON (I believe because the timer was constantly being reset at every scan). 2) Also using OSR with AWA was the only way I found of making AWA and TON to "behave" (that is, to make AWA only go ON once per start and the timer to go ON every time AWA is DONE). Would there be a better way to do this or is this acceptable? When I tried connecting "start" to AWA directly the program just didn't behave the way I expected at all, I believe because AWA would always be enabled for more than one scan, although I cannot explain why this would be a problem since AWA should only execute from the transition false to true, no? 3) I never clear my buffers or reset my ASCII instructions... when I try to clear in parallel with JSR some of the ASCII instructions' bit ER goes ON, and when resetting my ASCII instructions sometimes I don't see any before/after difference, but oftentimes I just see an undesirable behavior, and to be honest I'm not even sure where in the code I should do it, so I wonder if I should bother. More specifically, in which situations should I care about doing it when writing a program, and where in the program is it recommended to do it? So far I don't seem to have a problem, so I'm being willingly ignorant about it Any suggestion regarding my code/logic is much appreciated! Thank you!

Hi I am having trouble programming something I thought would be simple. I am using Word Lamp to display 6 different images ie. 6 states.  I have 5 Command Buttons. When pressed each one causes a different image to be loaded . What I want is the 6th image to display when the command buttons are released and before they are pressed. Unlike Bit Button which has a momentary setting , Command Button can only set a state. I wish it had a momentary feature so the state value could  be set when pressed and return to 0 when released. I hope I am being clear with what my issue is .  Any help with this would be greatly appreciated. Jim

Hi! I just started with PLC programming. I am trying to get the time between a output signal and a input signal. The problem is that the time is ~200 ms but when i measure it with this code:   TONR(Timer1); IF PosFeedback <= PosFeedback_Min & not Timer1.Reset THEN Timer1.TimerEnable := 0; FullCloseDeltaTime[1] := Timer1.ACC; Timer1.Reset := 1; END_IF; IF (move & not Move_LastScan) THEN //Start timer Timer1.TimerEnable := 1; Timer1.Reset := 0; END_IF; Move_LastScan := move; i only get even values in intervalls of 50 ms like 150, 200 and 250 ms. I have changed the real time sample rate to 11 ms so i don't understand why i don't get a more exact result. And i can see in my trend that the time isn't exactly 150, 200 or 250 each time. I i tried and time my own click on a button and i see the problem is the timer, i only get values in an interval of 50 ms. Is there a way to make the timer more exact?
