Can someone please help me figure out how to create a 12 hour long timer function in Sysmac? Or at least help me determine which timer function (in any) is best suited to create this long of a timer? Or will this require a counter instead? If so, does anyone have an examples on how to go about this? I'd like this timer to start it's function when powered up, and after the 12 hour timer is finished I will have it open a certain page on my HMI. Thanks!

Hello Guys. Is it possible to use an fr-a840 to use in the same time positioning control and also in speed control mode ? In the moment the vfd is in speed control mode. But now i also have to need to stop the conveyor in certain position. It will be a new feature. If its not possible, do i need a hsc ? The speed of the conveyor is 20 m/min and the accuracy should be within 3 mm. Could anybody help me with this. Thanks ahead.

Reset timer when input is shut off
New Programmer posted a topic in Allen Bradley / Rockwell Automation
Hello, I am no to programming. I have a timer that counts up output from 0-12, the resets back to zero. When I shut off the input, I want to reset counter to zero. What would logic would I use for this? Thanks Doug -
Hello, please help me deal with this problem. Mitsubishi GX Works 3. I can not understand why the TON function block does not work correctly. I need to set the timer in minutes, but if I set 55 minutes, the timer doesn't start and an error appears. How do I make a timer to avoid this? Going through the values, I found out that this happens with the numbers 55-110, although at times large numbers work adequately. t_0 - DINTflushing - TONapplyNewTime - Bit

when doing program, sometime really need a long period timer, I used to use RTO retentive timer, that can make 69 minute time delay. but recently I got problem. the production runs 24x5 hours, I have to keep one of my program function to monitor the equipment fault, I could not get the plc time by using GSV. the system time doesn't work. (all the other production lines, the system time work well, only this line 1769-L30ER 5330ER) By calculation, one day is 24x3600 seconds, six day is 144x3600 second, so I use CTU to count the every second, and use the CTU.ACC as relative time record. If the production line runs five days with no stopping, the counter will count to 120x3600 second, it's long enough to keep the monitor on. once the line stops, reset the counter to zero. waits for next starting up.

how to show timer countdown in vijeo designer
sbselect posted a topic in Modicon / Telemecanique / Schneider Electric
I have set up a timer in exostructure expert basic and am trying to get the contdown value from the preset of 20 to show in vijeo designer but it tells me the %tm0.v is read only and cant find the variable in Vijeo designer to show it. Does anyone know how to do this? -
Can You explain me how can I reset a Timer so that after completion of the cycle, it automatically starts again from 0 sec in CX Programmer? I am working on a program for a Oxygen PSA Plant. In which the valves of 2 cylindrical tanks switches at a specified interval and the cycle keeps on repeating. Thank You.

Hey all. Wondering if anyone has an example program they'd be willing to share? Specifically I'm using the 1734-VHSC5/C with a 1769-L18ER-BB1B PLC. All of Rockwell's wonderful information only refers to SLC-500 platform. I'm not trying to do anything terribly fancy, just have a quadrature encoder attached to Channels A & B, then using an output to turn on a valve at 8.0" and turn off at 10.0" Any help would be appreciated.

Hi guys! I need some help with a powerflex 525 multi speed configuring. I know I have to set the P046 parameter for 2 “DigIn TrmBlk” (source) and P047 parameter for 7 which means present frequency. This is the speed reference. I need 3 speed, so I will use Terminal 5 and Terminal 6. When both terminal is zero then 10 Hz, when terminal 5 is 1 but terminal 6 is 0 then 20 Hz and lastly if both terminal is 1 then it will be 30 Hz. I will adjust the speed with the parameters: A410, A411 and A412. Terminal 2 would be the forward and terminal 3 would be the reverse direction. I think these two can be two PLC digital output trough one-one relay. It will be counted the distance by an encoder. When it reach the target the run command will be released and the motor will be stopped with the decel time1. Also I will connect the S1 and S2 for safety. My question is do I have to connect other wires ? Also do I have to remove the jumper between terminal 11 and 1 ? Am I forget something ? Any comment would be highly appreciated. Thanks ahead.

I have a huge confusion regarding the retentive timers on FX3GE. According to the programming manual for FX3G(image attached), all retentive timers use the EEPROM. This is very confusing to me because the retentive timers are modifying the measured time constantly in an EEPROM register and EEPROM type of memory is known to be write limited. After a couple of million write cycles the EEPROM registers burnout. I've experienced this myself by constantly using the T250 and after a while it became unusable. The timer stopped counting time after some time. This leads to my decision that retentive timers on FX3GE PLCs are something that should бе used only on rare occasions so as to avoid EEPROM memory burnout. If this is true than the real question comes in: What is an alternative for using retentive timers on FX3GE when you want to measure time between two events. The instruction TTMR for teaching timer is appropriate however this instruction does not exist on FX3G series.

hi all, i am tring to program my fx1n on to a bag machine where there is a sensor which checks if the bag length is correct by stopping at the appropriate print also we have given a +5 or -5 to check if the print has moved and if moved to cut the bag from where the signal comes. when the colour sensor is off the plc moves the servo motor the the measure we have given and cuts no problem there but as soon as i give it to check the signal from the colour sensor the plc shows different length when i monitor and also it moves past the print and only stops. it seems its not stopping at the interuption. the colour eye is working we checked. if someone can help it would be greatly appreciated. if you can give a small ladder program which works would be even better :)

Hi, I have found this forum extremely helpful in the past. I greatly appreciate in advance any help/direction. I am having trouble simply placing/invoking a PRV instruction in CX-Programmer. The program seems to not recognize really any of the High Speed Counter instructions. (working with a CT021. I/O table correct, CJ2H CPU67 PLC rack powered on with all green lights.) Please see attached screenshots for what I mean... the PRV, PRV2, CTBL, SPED, etc instructions just show up red (like they are not understood/recognized PLC instructions/functions) when I try to place in the ladder. There must be something simple that I am not considering. Thanks again for any help. Michael

Hello Everyone, I am writing one logic and need some help regarding that logic. CURRENT LOGIC - -There are two timers TON_1 and TON_2. -TON_1 timer will start as soon as PLC turns on. -After the done bit of TON_1 timer, the TON_2 timer goes on. -After the done bit of TON_2 timer, again the TON_1 timer will start. -This logic cycle will run continuously, both timers will run turn by turn. Code (Codesys/Schneider Eco Structure Machine Expert)- PROGRAM POU_1 VAR TON_1: TON; TON_2: TON; END_VAR TON_1(IN:=(NOT(TON_2.Q)) , PT:= T#100S); TON_2(IN:=(TON_1.Q) AND (NOT(TON_2.Q)) , PT:= T#20S); Actual Requirement - -There is a BOOL tag. -If the BOOL tag gets high during the TON_1 running, the logic should move to the TON_2 immediately. -If the BOOL tag does not get high during the TON_1 running, the logic should move to the TON_2 after completion of TON_1. -after the completion of TON_2, again restart TON_1. -Logic Runs continuously in a cyclic mode. Give me your valuable idea to fulfill the logic requirement.

Good morning guys, in your experience what is the best way to syncrhonize a motor controlled in speed with an inverter and a motor controlled in position with a servo drive? Let me explaine better what is my situation: I have a belt running normally at a certain constant speed. in some moments, I would like to syncrhonize the speed according to an axis controlled from a servo. the command of a servo specific position target and of course speed and acceleration e deceleration rate. I would like to adjust the belt speed in way to follow as accurately as possible the servo movement. Thanks a lot Andrea

CP1E host link communication via serial port gives IC error code for Timer SV Read
S2N1992 posted a topic in Omron
Hi, I'm trying to communicate Omron CP1E unit with PC via serial port using hostlink protocol. I need to read the Timer/Counter SV value and write the timer/counter SV values to the PLC. I'm able to use other C mode commands (like RC (timer/counter PV read), WC (timer/counter PV write) etc.) but when I give the command for Timer/Counter SV Read 1 which is R#, I get the response as IC (Undefined Command). How do I write or read the timer SV Values? Example command and response : @00R#TIMH001028* (TIMH is the high speed timer, 0010 is the timer number and 28 is the FCS) Response: @00IC4A* Is is that CP1E doesn't support these commands? If so what is the equivalent command that I should send inorder to perform this? Please help. -

Hello everyone, I have a Kinetix 6000 CIP drive (unwind) and I need to control its speed by a PID controller. I have everything working except the MCD instruction doesn't pick up on the PID output value change. It changes the JOG speed, which I use to control the unwind, if I set the speed manually, which is slow. The PID changes the speed almost continuously. Any suggestions are welcome. This is how I'm attempting to control the speed: A1_r_JogSpeed = PID output value Thank you

Hi guys, I just starting to use Sysmac Studio. Its a bit confusing as I am currently used to CJ series PLC. Usually, we can use P_1sec, P_0_2s and so on to create a simple clock pulse timer function. However, I couldn't find the command or FB to do that in Sysmac Studio. Anybody could explain on how to do that in Sysmac? Thanks

I am using fatek FBs 32MN PLC. i need to run the nema stepper motor synchronized with induction motor's speed with some ratio. in my case the speed of stepper motor will change as the speed of induction motor changes its speed, may be many times in a second. Problem is that the speed of stepper will be constant as before until i have to disable and then enable again HSPSO function. is there any solution that i can dynamically change the speed of stepper without disable and enable HSPSO function ?
