We are having issue on a machine running kinnetix 5500 drives where we randomly get clock Sync Faults. This particular machine is set up as a slave looking to another PLC(L36-ERM) on a different station of the same machine as the time master. There are about a dozen other PLC's(totally different machines) on the same network and most are set up as masters for their own systems and to my knowledge they have never had this issue. There are also dozens of other devices connected to this network, and then this network is part of the facility wide network.( I apologize if this is a little wordy) We are pretty sure that the slave is finding a more accurate clock on the network somewhere and syncing to it causing the servos to fault. We have tried making both the master, and the local clock of these 2 particular PLC's higher priority than the others to eliminate this with no success. What I am trying to do is track what clock this particular slave is looking at as its master when the clock sync fault has occurred. is there away to do this through ladder logic? it seems like we should be able to get this information and save it so we can figure out who the culprit is.

Still learning Sysmac Studio......how do I gain access to System Variables like 'PageIndex" so my PLC can be notified what Page the HMI is on? Also, how can I execute an 'Acknowledge All' from the PLC so I can reset the 'Alarm Viewer Popup' from my PLC? Thanks,

Time synchronization of L71 via 1756-TIME
Arizona posted a topic in Allen Bradley / Rockwell Automation
Hello Everyone, I am new at this forum, seeking help from you guys and gals. Scenario: I have a Controllogix 1756-L71 5570 controller installed with 1756-TIME module. The function of time module is to take time from GPS clock module in NTP format and send it to controller in PTP format. All the status LED's on Time module are OK. Also sync LED is Green. Still the time of controller is not synchronized with GPS clock there is a difference of 45 mins. Fellows please help. I'll be helpful. -
Hi everybody,For a while I’ve been wondering, in every plc forum where the use of loops come to discussion I find most people answering that it’s best to stay away from them and that there are better, easier and mostly less scan time demanding solutions out there. Why is that?In my experience they’re the next best thing.Why would referencing data from an array of 40 Dwords using a FOR X:= 0 TO 40 DO loop be any more scan time demanding then the PLC scanning through 40 rungs of statments?Just curious if I’m missing something here. Cheers

Hello, I used a Schneider Electric SR3B261B PLC to create a trivia machine (as I call it). Basically 20 buttons that let contestants ring in to trivia. There is a display that shows the number of the person who rang in. It works pretty well unless people press the buttons at exactly the same time. Then it shows 2 results at the same time. Usually resulting in a display of 18 when really it was 12 and 14 that rang in, for example. The PLC has options for: "Adjustment of the basic cycle time of the module." and "Type of Hardware Input Filtering." Which I assume would make the PLC operate faster and avoid two inputs triggering at the same time. If I change the setting and update the changes do not keep. I appear unable to change it past 20 x2 ms and slow (3ms). Is that a correct assumption that changing this would fix it? Why can I not change this? Is it because I have so many inputs (14 or so) and Outputs (16 or so)? or because my program uses nearly all 240 lines of ladder logic allowed? What can I do to fix this? Emerald

Hi all, I am trying to update the firmware of a NS12-TS01B-V2. I have downloaded the RecoverUpdate_8_95.exe (and someothers) from the myomron website. I have followed the instrucctions PDF, but when I switch on the HMI with the Compact Flash inserted, nothing happens: the screen is dark and the led is lit orange (not blinking). The compact flash is 1GB (not omron) and formated using a CJ2. I have been using this card in OMRON PLCs and HMIs for years without problems. I read in other topic than I guy had similar problems and he solved it using other computer and other unzipper program. I have tried it, but it did not work. After that, I tried to update it using the DIP switches, but I got more problems, because I got a Warning first, and later an Error, because I forced the installation of the Firmware of the NS8 (BANK1) instead of the NS12. However, the other BANK folder contains the FW for the NS5... Anyway, I could fix this error because previously I did a backup of the already installed system (V7.0). I would like to ask you to send me a BackUp of another NS12, using the "Manual Transfer", that should works. I need the 8.20 version or higher. Thanks a lot. My email is hector.moreno.lax@gmail.com

Micrologix 1400 recording off time of a DI
Ryandevlin17 posted a topic in Allen Bradley / Rockwell Automation
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) -
I'm very new to sysmac. I am trying to display the current date and time in the corner of each of my HMI pages. I saw a button labeled date and time. It is asking for a variable for behavior. Do I need to write some basic structured text or FB in plc to get date and time and pass it over? I figured the button would update itsself since when I placed it on the screen it had the current date and time and refreshes every time I leave the page and come back.

I would like to capture current date and time to registers in the PLC. I would prefer to use a function block, if possible, since I need to do the capture at different places in the program. I am using a CJ2M. How can I do it?

There have been many good discussions on the applicability of cloud-based solutions for manufacturing and process control systems. On one side, some people have concerns regarding security and control of the information, on the other side, there are identified benefits enabled by cloud systems. From VMS minicomputers to DOS and Windows, from ArcNet to Ethernet, it is inevitable the industrial automation systems shall adopt the technologies that are getting predominant in IT general use; the current environment that I am calling the “Cloud-iPad era” is no different; therefore the practical discussion is not if those new technologies will be applied in the industrial environment, but how. This paper is not intended to join the conceptual discussion about the cloud, but just to present a few simple practical examples, where cloud technologies are already enhancing industrial automation solutions and enabling new business opportunities.

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.

Hello, Completely new to Mitsubishi PLCs and I need to use a date and time stamp for data collection purposes. We have a Siemens PLC as well and this has the data type "Date_And_Time" which is what I need to replicate. I have been attempting to write my own data type but am struggling with how to go about this as it is not straightforward and I cannot find anything about how the Siemens Date_And_Time is made up so I have nothing to go off. Does anyone have an example of a data type they have made that is the same? Or is there a data type which does this already in GX Works 2 that I just can't seem to find? Please help!

Hello - I am currently setting up a program to control a downlane conveyor motor and ran into the issue of operators leaving the conveyor on through their breaks/at the end of the shift.... I know, shocking . Anyways, the essentials of the program are the following - ladder logic, start/stop PB station, a sensor that says when I've seen a box for x-amount of time I will turn off, when the eye is clear for x-amount of time I will turn back on. When trying to 'solve the problem' of the operators leaving them on, I figured this would give me a chance to use a RTC (real time counter) and program it so that at various times of the day I will send a single shot to verify the relay is CT is open. I've enabled the RTC on the Micro810, dropped a TOW but do not really understand how to set the TOW block up. Hopefully that all makes sense. Thanks, grubb

Periodic Tasks Effects on Communication
Twigums posted a topic in Allen Bradley / Rockwell Automation
OK, I have a program in a Control Logix 5561 controller(ver. 19.52) that every time we go online with it, the communication between the PLC and the PC running RS5000 is so slow you cannot navigate the program efficiently. I am new to this facility but I noticed the programmer used 20 different periodic tasks to organize their program, mostly running at 30ms intervals. several are set to 10ms and some are even set to 3ms. I have gone through and found out that the short interval tasks have been overlapped 10's of millions of times, and the combined total of all scan times is over 160ms. I have a strong feeling this could be causing our comms bog down and possibly other erratic behavior but would like a second opinion. This machine has 2 indexing dials, with work stations that do work between indexes, Pick and Place operations, etc. Is there even a need to be running these with periodic tasks? All thoughts are appreciated. Thank you -
Rotation animation in Factory talk view
Lakshmi posted a topic in Allen Bradley / Rockwell Automation
Helo All, Thanks for your support on my previous quiry. Iam now facing an issue with rotation animation of a motor in factory talk view. I have a screen containing 5 motors and good number of numerical displays. Numerical displays need to be updated just every seconds ,so i changed screen updation rate in SCADA as 1, changing so decreased my motor rotation speed. so do i have any other option to change motor animation fast keeping numerical display screen updation rate as 1 second?? i have used the tag syste/blinkfast -
