Dear Team, We are looking for a suggestion to drive a motor which is away about 2100 Meter from its starter. The Pump is located in a pond in the forest which is 2000 Meters away from the nearest building. The pump capacity is 55kW and we are considering 55kW HD VFD as a starter. As we see the distance is much higher we are looking for you valuable suggestion about how this thing is gonna work without any abnormalities.

Ok I'll try a different angle of attack. I have acquired an S7-1212c unit. It is just too new for my TIA portal, which is V 15.1 The new PLC I have has firmwear 4.5 the TIA portal I have only supports 4.3, I get some errors regarding synconization etc. and it's like there are some tins that don't work. how do I update the TIA portal to the correct firmware I've tried updating the HSP files but it doesn't change anything https://support.industry.siemens.com/cs/document/54163658/how-do-you-update-the-hardware-catalog-in-tia-portal-?dti=0&lc=en-DE

Hey everyone, I'm new to programming PLCs and I've run into a problem. I have a Micrologix 1400 Series B PLC, and for the past month, I've been using a free trial of RSLogix 500 Starter. But now, the trial ran out, and so I bought a license for "RSLogix Micro Starter". The problem is that when I downloaded my updated file to the PLC for the first time with micro starter, the PLC's outputs don't work anymore. I checked the PLC screen and the inputs from the HMI screen are getting recognized, but the inputs from the physical sensors are not. Also, none of the outputs are being activated on the PLC at all, which I can tell by looking at the I/O status on the PLC screen itself. I then uploaded a new test program, where you press a button and a light turns on, but that doesn't work either. I haven't changed any of the physical wiring, only thing I've changed is that I'm using RSLogix Micro Starter as opposed to RSLogix 500 Starter. I spoke to a Rockwell technician about this and he said that there shouldn't be any problem, as I haven't done anything wrong. So I now ask everyone on this forum if they could help me out a bit.

Hi gentlemen, I have I bottle capping machine and I'm reading the torque value from one of the Sureservo2 drives. As the bottles pass through the machine, I need to display the peak torque value and hold it until the next bottle passes through. This machine could run up to 100 bottles a minute. I would also like to display a 10 bottle peak torque average. Does anyone know of a good way to do this? Any help would be appreciated.

Hello there, I am new to the forum and had a question regarding a setting in Sysmac Studio. In the Basic Settings for my NJ301 there is a setting on this particular line that is set differently than the other lines I have worked on. This setting is called "System service execution time ratio". On all the other lines I have worked on it was set to 10%, on this line it's 25%. This line also seems to have the most issues with controller performance out of all the lines I have worked on despite having less complexity. I was wondering if anyone knew what this setting actually does and if it should be changed. Thank you.

Hi all, I'm not shure if I saw it once, a Spanish site with a rugged I/O shield for an arduino plus a software package to build an Arduino-PLC packet. It was pretty much $$$ raised... (on my oppinion, for my application, not to dispretiate their value). Has anyone thought of it or knows of such an ensemble: A general Arduino board, a general kind of "plc-shield" (some inputs, some outputs,...) and finally, a (preferably open-source) software package to make an off-the-shelf Arduino-PLC ish? Maybe it all exists with some name changes, or this question is of a huge ammount of ignorance. Thanks. Corvo (means Raven)

DO C-more (and other) HMI's work well with Emerson stand alone PLC's?
junkyardgary posted a topic in HMI & SCADA
We have been tasked with saving money on equipment within our 4 plants here in the USA. I would like to investigate using low cost HMI's, I've had great success using C-more in the past. Has anyone had any of the several low cost HMI's attached to Emerson PAC (AKA GE Prophecy) PLC's? has there been any connectivity issues? I'd like to try one to replace the Emerson HMI's which are hard to source, and expensive. I believe any time setting up a low cost option would offset the cost of the Emerson, and open up our choices of HMI's and not be boxed in to one brand. We also use Profinet along with Ethernet connection, I believe the Emerson HMI only uses Ethernet (for us) but if there is a Profinet version that is easy to set up, that would make it an easy sale for me. This HMI would also have to work with the older 90-30 series PLC's, but i'm pretty sure the communications have not changed much from the to the stand alone RSTi-EP and RX3i PLC's. Any advice would be appreciated. Have a great week. -
Question About PLC Programming for a Concrete Batch Plant
domster2003 posted a topic in Automation Direct
Hello all, I am working on a batch computer for a concrete mixer, and the computer that was running the plant before has stopped functioning. It was an old PC running MS DOS. The code is encrypted and replacing it is not a cost effective option. I therefore am looking into using a PLC to control this batch plant. I have a setup that was in progress by another employee who no longer works for us, it is a CLICK PLC from Automation Direct, and it is supposed to be paired with a EA9 T8CL touch screen HMI from the same company. I would like some advice on just some basics, I would greatly appreciate some input. I essentially only have one input, and that is an analog scale, 0-20mA input. I have digital outputs for sand, gravel, cement powder, and a water meter for adding water to the mixture. I have one final output, an additive for reducing the required water in the concrete. What I would like to create is a program that when it is told to start, looks at the scale, and if the scale is less than say 100 pounds, opens sand until it hits 1700 pounds (as an example), then turns it off. Then it turns on the gravel and adds that for another 1700 (again for example, all these are variable), turning the gravel off after. Next the cement, and so on. I don’t need someone to write the program for me, but can someone point me in the right direction on using an analog input to turn digital outputs on and off? Again, your help would be greatly appreciated. Thanks for taking the time to read this long post. -
How can I access an UR5 robot through Studio 5000?
Lucas Antonelo posted a topic in Allen Bradley / Rockwell Automation
Hello, everyone! I am following this YouTube tutorial where it teaches you how to add a block of Modbus server within Studio 5000 for communication with plc ControlLogix. The video: https://youtu.be/qcF4m7rPjkw However, according to a comment from the author of the video himself in my comment I can make such a connection through a Modbus device. How do I do this within ur5 and how can i access UR5 inside Studio 5000? -

Hello, I have a problem that I need to solve in a PLC program has it's projectlib locked. I work for a company that contracted a PLC programmer before my time to program their new version of their control cabinets. The company did not write any specific contract with the contractor and just relied on his work. The guy later delevered a buggy software that is kind of functional (the bugs came up at the commissioning after the guy was paid and now he refuses to help or to provide more consultations). I have as a task to freshen this up and make it work without bugs, the problem is that the Projectlib is locked and I cannot access the source code. The only thing that I can changes that I can make to the code is to put some logical circuits between the I/O of the already existing function blocks, which solved some problems, but not all and it keeps one of the most important ones as well. Anyways, that's my story, so now my question is, is there and possible way of unlocking the projectlib? Any feedback would be highly appreciated. Thanks in advace!

I have a PLC ladder logic problem that I am stuck with and would like to know if there is a solution for it. PLC Ladder Logic Problem on PLC Fiddle: Automatic Window Blind There is a window blind that is controlled by using an opening and closing motor. There are 2 IR sensors that act as limit sensors to identify the boundaries of the opening and closing of the blind. The blind can either fully open or fully close. The blind is fully opened during day time and is fully closed during night time. We assume that the day time is for 12 hours and night time is for the other 12 hours. The PLC ladder logic must include at least a SENSOR, an ACTUATOR, a TIMER, and a COUNTER. You may use PLC Fiddle to draw the ladder logic: https://www.plcfiddle.com/ The process is as follows: 1. Assuming that the blind is now fully closed (during night), the night time 12-hour count down starts. The counter is done using a timer that counts 1 second, and after every second, the counter goes down starting from initial value of 12 (1 second represents 1 hour count down for simplicity). 2. When night time counter reaches 0, the counter resets back to 12 and stops, then the blind opening motor activates and keeps running until the blind edge reaches the opening limit sensor. 3. The opening motor then stops, and the day time 12-hour count down starts. The day time counter operates the same as the night time counter. 4. When day time counter reaches 0, the counter resets back to 12 and stops, then the blind closing motor activates and keeps running until the blind edge reaches the closing limit sensor. 5. The closing motor then stops, and the night time 12-hour count down restarts again. The whole process is repeated again. Please find attached below the rough sketch for the idea. Feel free to either sketch the ladder logic or use PLC Fiddle (link above). Thank you.

[Discussion] Do you think a framework for building and implementing a (simple) SCADA is needed?
zenithie posted a topic in HMI & SCADA
I hear a lot of people talking about the annoyance of price estimates (meaning they don't get a clear, transparent price from the beginning) and the costly engineering that seems to never end. Do you think that a step-by-step, clear process and course of action from A to Z would be beneficial for companies? And I'm not talking here about SCADA software, like Ignition. I'm talking about using Ignition to build and implement a fully working SCADA solution, customized to your company BUT you know exactly the price and the methods/processes that will be used (it's a replicable framework to get similar results for multiple companies - and the results would be a SCADA solution without the headaches of the unknown prices and engineering characteristics). Basically, a clear project-based approach rather than an hourly approach where things can get confusing. Do you think the industrial space could use something like that? -
Has anyone had the opportunity to work with Automation Direct's new "Productivity 2000" PLC? I have personally had the opportunity to use their "Click" PLCs which are, as advertised, very cheap, but effective. These little plcs are similar to Allen Bradley's micrologix line of processors, but definitely are not as well made. The software is free (a nice bonus) but definitely lack in features that you would get from the Rockwell folks. Still, for a simply job on a tight budget they work well. As for the new Productivity line, it looks (from a software side only) like many of the features you would find on the Contrologix and Compactlogix systems are now available. The user interface looks relatively clean and easy to use (Coming from an Allen Bradley background). So...any thoughts on the Productivity 2000?

Hi guys I am having trouble installing GX works 2 software. The software is fully legit and came with 2 license keys the first one I put on work laptop and second on my personal laptop. The install all goes fine but when i try open up GX Works 2 I get this message from the attached image. I have plenty of room on my pc and even have other PLC from different manufacturers on it without issue but the GX Works is just giving me grief and I have tried to increase data on MY laptop and other windows fixes but still get this message when I try open it. Has anyone else encountered this problem before or any ideas? Cheers guys

I am attempting to use EPLAN P8 (v.2.9) to import details from a 'holy grail' excel sheet of a cable list with terminal tags and numbers (source and target for each cable). To do this I began importing details in a trial and error fashion through the pre-planning menu to the pre-planning navigator. I have several questions. Question (1) Has anyone else tried to do this? In the process of importing from the excel sheet I have not been able to successfully assign source and target for each cable object. It shows up on the synchronization dialog after I work through the field assignment but it disappears after import. ( I do not fully understand the proper structures, definitions, properties and levels to get what I want). I do understand if I import source and target terminals, and cable objects separately, then I can place on the detailed view and source and target are assigned then. Question (2) Does anyone know how to assign source and target to a cable object in pre-planning 'by import'? (Reason being that the excel file is huge and manual assigning isn't feasible). On one of my attempted field assignment schemes I was able to have cable, source terminal, and target terminal, all on different levels (not actually assigned as source and target for the cable object btw.). However the result for source and target on the report (planning overview, form: f40_006) had all of the designations of the tree structure from the upper levels. For example, cable: HAC4401, source: HAC4401 X1:5, target: HAC4401 X1:5 TB1:5. (Where X1:5 is source terminal and TB1:5 is target terminal). Question (3) Does anyone know how to create a 'branch' or 'fork' in the tree structure in the preplanning navigator so that both source and target terminals (planning objects) are on the same level and so do not inherit each others details? There's a bunch of info in reading the above I know, but if anyone can shed some light on this it would be much appreciated!!!! Thanks in advance, MajorMac
