can anybody Know how to control stepper motor using PLC

Hello, A while ago I modernised a magazine gathering / filmwrapping machine. This was a fairly big project for which I used an Omron CJ2M as the main PLC, 10 Wago Ethernet/IP fieldbus couplers, a Keyence CV-X420 vision camera and an Omron NS12 HMI.  All of these components run on the same network which contains an unmanaged switch where the HMI, PLC and the first Wago are connected. The Wago’s act as a two port switch since they are all daisy chained. At the end of the Wago chain there is also the vision cam which is connected at the last Wago coupler. At the time I was advised against using Broadcasting instead of Multicasting with a managed switch, but I tried anyway since my networking knowlege is lacking. Also, the only ‘bandwidth demanding data’ comes from the vision system. The Wago couplers contain only digital I/O and high speed encoder inputs run directly to the CJ2M. I haven’t run into any trouble so far and the machine is already producing for over a year. Now , a new project is on the way and it will need even more Ethernet couplers, 15 to be precise.  This brings me to my question; is there a limit to the number of nodes in an Ethernet/IP network and will I possibly run in to bandwidth problems by adding more remote I/O and not using a mannaged switch? Also, I would like to get high speed input out of one of the Wago couplers. Thanks in advance for any feedback! Greetings from Holland Andy 

Good day, how can I send string data by buil-in ethernet. Maybe word 'TRIGGER,?

Hi, I am using PID function (PID operation instruction) from GX Works 3 library but it doesn't work. I set all necessary parameters (sampling time, direction and upper/lower limit values + KP, TI). My input PID_Par is array of 25 points (in manual is written: "*1When auto tuning is not used, the same number of points are occupied as when the step response method is used."). For example, in GX Works 2, PID function works ok. Did someone have similar problem? Does someone have mitsubishi library (GW Works 3) with PID function that works correctly?   Regards Luka  

Hello,I am sizing a feeder circuit for a panel according to UL 508A and came into a question:My input current is of 76.5 A (considering all the loads), thus, it is fine for me to use a cable of 4 AWG (max. 85A @ 75 c).For the circuit breaker I did 76.5 A x 1.25 = 96 A and then I selected a breaker of 100A.My question is: Is it ok for me to keep this configuration according to UL 508A? 100A breaker + 4 AWG load side cableOr do I need to level up the cables?Thank you very much in advance!

Hello guys, I am facing a problem that our Servo is generating output for only reverse direction, when we give forward command from HMI the output Y0 is active but when we give reverse command same outut Y0 is high, other output which is Y4 is not high, what could be te possible reasion.

Is it possible to setup Ethercat parameters from within the PLC program?  I am facing a situation where a machine is going to have changeable tooling fixtures and each fixture is going to have an EtherCAT device on it.  I am guessing they will need to be setup to look like the same node to the PLC, but they will have different physical IDs and different settings for some of the parameter fields.  They will be the same device so they will have the same parameter fields, just different values in those fields. I can also get these devices with EthernetIP as the fieldbus option.  In that case I would always have a network error because the PLC would always see one of the devices missing from the network.  is it possible to enable/disable Ethernet connections from within the program logic to avoid the error?

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.

So I need to find a way for a Mitsubishi PLC to communicate with a PC - ideally sending a binary number through ethernet to a PC program that reads it and tells the PC which files to open. I think I can create the PC program with C++ or Visual Basic without too much struggle. But I am unsure of how to get that binary ID from the PLC and into the PC program. I have done a little bit of research on MX Component and MX Sheet, and also MC Protocol but all seem a bit outdated and/or just over my head and I need some better explanation - I'm pretty new to PLC and programming. I feel like it shouldn't be terribly difficult to get 1 external binary number into a PC program. I'm sure someone has done essentially the same transfer and I just want some ideas. -What kind of connection support do I need to transfer data (Likely just a D-bit) from a PLC to PC? -How would that/those bit(s) be accessed in Visual Basic or C++? I'm assuming some type of library function that will call the value

Is it possible converting Omron and Keyence plc's serial communication into Ethernet using serial to RJ45 converter?I need to connect these plcs with MOXA 5600 terminal service for communicating it to the Server.Thanks in Advance....!

Hi :        IF there are 10 global variables in the NX102        Count_1....................Count_10 (all of the variables are UINT)   what is the   Class ID Instance ID. and Attribute ID for reading from and writing values to the above said variables? I am unable to find the the appropriate manual below is an Application that is able to peek at Omron EIP PLC https://sourceforge.net/projects/enipexplorer/

Good day, I have Mitsubishi SN 18xxxxx with new firmware 1.111 and attached FX5-ENET/IP module to communicate with SMC EX260-SEN1, have you any example how send data into SMC over Ethernet/IP? Thanx for reply

What are all the possible way to fetch data from nine Omron CJ2M-CPU13 for an OEE application. Is it possible to communicate by adding an EtherNet/IP module to it. I need to connect to Kepware Server.

Good day, I am new in mitsubishi and have a question about how build built in ethernet communication on fx5u fw 1.050 gx3 1.047 with smc ex260 sen1, where i need send 2 bytes and receive 4 bytes can u help me? I try to send data with this format 2#0000000100000001 and send by Ethernet Active Tcp connection library where I have added the external device configuration ip and port SMC EX260 SEN1, I think I needed use a CIP protocol and port 44818 or Ethernet/ip, maybe I need add a ENET module to use this communication between my devices? Thanks a lot for answers

I have a control that I want to use a Direct logic 05 plc in.  It is a really simple program but it is going into a plant that has a main control panel that runs the plant.  I dont know the brand of the plc in the main control.  They want to be able to send me a command from their plc to the direct logic to turn on my unit.  I suppose that would mean a simple set instruction to my plc.  I also have a couple alarm conditions that I want to send them.  For example if water pressure is to low I would put my unit in the alarm mode and send them a low water signal.  If the chemical is low likewise,   I dont have a clue how to do this in my program.  Can anyone give me some examples in direct logic plc program for making this happen??? Thank you Thank you Thank you. MikeC

Hello - Not sure if this is the right place, I apologize if not. Just let me know if I need to move it and can delete and do so. But I am currently working on a project where I am collecting seeds (flower seeds, etc.) and when a certain weight limit is met I'll be turning off a vibratory bowl and opening a chute, etc. Looking for some ideas on the scale and how to do that process in particular. The smallest collection weight will be around 100mg, largest around 8g.  Mainly looking for ideas on the scale.  Thanks for any help/tips, much appreciate.

I have a fx5u plc connected to 2 keyence sr 1000 qr code scanners using plc link. On random times the plc error light will light up and all ethernet connection will be disconnected and i cannot connect to the plc with gx works 3. If i put the plc in stop mode tho i can connect to the plc. I do not know what error code is causing this because each time i connect the error code is missing. The problem starts when the plc is in run mode. Can anyone help me with this as this is a persistent bug that keeps on happening in my system?

Hi I am using a P342020 together with a HMID642 Magelis Panel. Using Unity Pro I have successfully downloaded a program to the CPU via USB. The HMI Panel powers up into 'Initial Start Mode' and is asking me to 'Download the system from your editor.' How is this done? How should the ethernet connections be made? between PC (with Unity Pro and Vijeo), M340 and HMI panel and where do I set all the IP addresses? I guess there is documentation somewhere but couldn't find it...! Regards   Andy
