  1. Hi all I have a project where i am building a bread softness tester.  To do this i am using a smc electric actuator and an A&D scale. The electric actuator will push down on a slice onto an A&D scale.  A micro830 plc is then reading the data from the scale and storing the real variable in an array 80values long.  I would like to display on the hmi (panelview800) the peak/maximum value in the array. I am struggling on how to do this though and have not found much information online. any help would be much appreciated Thanks in advance Trevor
  2. GX Works 3 - PID control

    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 want to connect an Allen Bradley 1768 L43C PLC with an anybus Ethernet/IP Scanner X Gateway. Unfortunately the PLC doesn't recognize the anybus X Gateway, I attached some pictures of my configuration. Do somebody knows whats happening? Thank you. p.s. Help!! :( error allen bradley.docx
  4. 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!
  5. Connect PLC to Kepserver

    I have Delta 12SA2 PLC it has RS232 port and I have connected it to kepserver (by Modbus serial) and then factory IO Now my problem is that when I connect my PLC to kepserver the RS232 port becomes busy with the kepserver and not available in the ISPSoft and therefore I could not demonstrate factory io and my logic in run mode in the isp soft together like you do in your videos. My PLC don't have ethernet port but is there an option in kepserver or any way by which i can use the same serial port of the PLC in isp soft run mode and kepserver+factory io together so that I can simultaneously show the logic running in isp soft and application working in factory io to my students. I googled a lot and found some softwares which make virtual serial ports for a given serial port but they don't work and soon hang Please help me I am in a great need of it. Thanks in advance.
  6. MODBUS-RTU slave

    At this moment I was asked to change one CJ2M's program (in Ladder, and the PLC is the slave) in order to make a list of desired variables "readable" by the master (an host computer/ SCADA) wich is using the protocol MODBUS-RTU. I only have to work on the PLC' side and i only know the name of the variables and their corresponding address.I already read the "CS/CJ Serial Communication Unit Operation Manual" but i still have some doubts:- The only way to define my slave address is done by writing a code to put the value of the address on the corresponding bits of DM area? or can i define the address using some feature of CX-Programmer?- (A CJ1W-SCU41-V1 is already implemented in the field) on the slave'side i only have to make sure the variables are allocated on the right place, according to the master's commands and modbus' addresses, right?- I read something related to the frames sended by the slave as responses for each master's command, am I supposed to write some code to do this task or it is done automatically?- Imagine the master is using the "Read coils" command, in OMRON there are 4 memory area associated to this data model "Coil" by default it is associated to CIO area, can i switch in the slave to Holding area without problem?Sorry about my english and this extensive text. Thanks.
  7. Mitsubishi FX2N, Servo Output problem

    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.

  9. Modbus TCP/IP iQ-R series

    Hi, I have R04CPU (iQ-R series) on one side and on the other side is QJ71MT91 (modbus tcp/ip module). Is it possible to make communication between them (QJ71MT91 is master and R04CPU is slave)? iQ-R series doesn't have Modbus TCP/IP module, but is it possible to set modbus tcp/ip on built-in ethernet port of R04CPU, and how? Best regards Luka

  13. 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.

  14. Hi experts, the pulses counted in my flow meter are not the same with what is counted in my PLC. my flow meter is set at 1 liter per pulse, and the pulse width is 100 mili-seconds  my PLC filter is set at 5 micro-seconds. example for 12-13 seconds in my flow meter readings 23 liters will be dispense for the same 12-13 second it shows 12 liters dispensed on my HMI. please what settings are required to make both the PLC and flow meter count the same ? am using high speed counter for this application. Please i will appreciate any contribution to enable me solve this problem  thanks     
  15. CCW/Micro800 series

    Hello all! I have a two part question - both revolve around using Rockwell's CCW software. 1) in rs500 you can mov a value into the an int memory slot and call that int up later on for comp. instructions to see where you're at. Example, if x switch is active, mov value 0 into N7/0. If y switch is active, move value 1 into N7/0. If both x & y are active, move a value of 2 into N7/0. How is this done in CCW??? I've found the mov command but not sure where/how to store this value. 2) How do does one shot [ONS] work in CCW?!? From what I've gathered the r_trig and f_trig is its replacement, and thought it made plenty of sense. But no matter what I do the triggers never work out correctly. Thanks, -g

  17. logix 5000 array

    Hi Guys! I have a problem with array filling. I use rslogix 5000 software. I have to save the timestamp sometimes. I can save it with GET instruciton. Its a dint array which have 7 elements (year, month, day....and so on),  But my problem is I dont know, how can I solve that, they are in a bigger array. So like an array within the array. Idk it is possible ? I hope you know how I mean.  So I have 7 dint value in one array, and I want 1000 array for this. How can increase the position of the array number ?  Can anybody help me with that ?  Thank you in advance.

  21. Codesys

    Hello - I stumbled across some mention of Codesys and was curious if anyone here uses it. Pros/cons? prefer it over other programming software. Have it downloading currently (since you can download a free variation of the application) but it looks quite interesting. Also - what PLC hardware is programmed with it? Did not see that mentioned on their website when I was browsing through.

  24. EN2T/D, DNB/E, Devicenet Issues

    Issue suddenly began about 3 weeks ago...or I noticed it anyway. I opened devicenet to change a parameter in a drive but all nodes have a question mark on them and RSNetworks will not register them no matter what I do. I checked RSLinx and I see question marks on The DNB/E modules and on the EN2T/D modules. I made sure I had the eds files and AOI's for these modules but nothing changes. I have uninstalled Networx and changed versions several times but it comes up the same way. I am using RSLinx version 4.10 and now have RSNetworx version 28. Any ideas? Thanks in advance.
