  1. hey!  I'm pretty new to PLC's, and I'm supposed to ''teach'' the people at my internship how this PLC works, but I have encountered a problem.  I've gotten pretty far with all the digital programming and understanding how everything works, but I just can't figure out how the analog inputs/outputs and programming works...... I've had a fair explaination on PID and how this works. I've searched the web as well to figure out what PLC instructions to use.    I hope you can answer my following questions.    1, what are the most used PLC instruction blocks which I can use for temperature control, and how am I supposed to use them? 2, Could you please give me an example on how to use PID and what numbers will I need for the calculations? 3, what are the most used PLC Instruction blocks (apart form the analog ones) that I should include in my tutorial?   this is my setup: Ethernet switch MOXA EDS-205 Plc voeding PA202 PLC CPU CJ1MCPU11-ETN Digital IN (16x) CJ1W-ID211 (SL) Digital IN (16x) CJ1W-ID211 (SL) Analog IN (8x) CJ1W-AD081 (SL) Analog IN (8x) CJ1W-AD081 (SL) TRANS OUT (16x) CJ1W-OD212 (SL) TRANS OUT (16x) CJ1W-OD212 (SL) Analog OUT (4x) CJ1W-DA041 (SL)   thank you soo much for looking at my question and considering helping me! the OMRON helpdesk hasn't been very helpfull.    kind regards,    Deuslupos,

  2. omron ea5k-aa2-500 help

    mr.uba posted a topic in Omron

    hello, looking for some troubleshooting help with an omron ea5k-aa2-500 controller. I work in a conveyor belting shop and the controller in question is one of two used in the control box for one of our belt presses. the controllers work in tandem to control the temperature of the bottom and top of the press heads. Recently a co-worker was dialing down the set temperature on one of the controllers and might have went out of the limits of the program. Now it is stuck in some type of shutdown loop. When powering it on it displays "0000" on display#1 before showing the temp. value and the set value of 0 for a split second , then turns off and loops. My question is if there is someway to reset and re-program the controller, or is it time for a new one. Sorry for the lack of knowledge of the controller, any help would be greatly appreciated.

  3. DC motor with encoder

    Herant posted a topic in CX-Programmer

    Hello, The company that I work for wanted me to design and build a FIFO loader. For those who do not know what a FIFO loader is, it's basically a lift that runs up and down and filling up the magazine slots with pcb's. After I finish the mechanical part i'll try to program it by using a CPM2C - 20. I have already played with CX-programmer and learned my self a bit, for example how to program simple things such as AND and OR gates for controlling motors and lights. Really hard part for me was figuring out how to create a program that reads data from the encoder and use it to create positions which the motor will stop at, and i have not yet figured it out. I've been trying to google it without any luck, the only thing of real info i've got is a 650 page long pdf file or CX-Programmer manual which is hard for me to read since i'm new to all of this. Would be great if any of you people got any source or maybe a manual which are easy to understand for new beginner like myself. A bit about the program i would like to make: The FIFO loader will have some buttons for selecting different programs, lets say you press first button to select "program 1". Then the machine should move up and stop at posision "50" (there are 50 slots on PCB magazine) after it gets signal from pneumatic actuator (which will be used to shove pcb inside the slot) its should move to position "49" and so on.. If FIFO loader is located at "home" position and you press second button to choose "program 2", then it will move to slot "49", wait until it gets loaded, and continue to slot "47" and so on.. The meaning of this is to make a loader which can select a program to fit pcb's with different size of components.
  4. Dear colleagues, is it possible to operate two working Modbus units on one PLC (FX3u)? For example, one as serial Master with FX3U-485ADP-MB and another TCP Server with FX3u-ENET-p502?    
  5. hello guys is there any one know how to setup default gateways on OMRON PLC CJ1M? cause there is only setup for IP address and Subnet mask.. am trying to control the PLC using Ethernet through Wide Area Network.. so if there is no Default Gateway, the connection PC to PLC will totally lost
  6. I have an application I am currently working on where I have a single AB ControlLogix PLC that needs to read data from 12+ Omron CJ2M PLCs.  The Omron PLCs don't need to read any data from the AB.   I have tried several things including the generic .eds file from Omron and the instructions in the document I found on this site:  Omron CJ2 to Rockwell ControlLogix Ethernet/IP Datalink.  The generic .eds file gave me a D6 error on the Omron side and after talking to support it does not seem like the correct path.   When I tried following the instructions for the datalink I ran into several issues.  The first issue was that after configuring my network in the Omron software upon trying to load it I got a unit mismatch message for the 1756-EN2T, the .eds file I have is for a 1765-EN2T but the card shows as a 1756-EN2T/D, so I am concerned that could cause an issue...that being said I can't find any .eds file specifically for the /D revision.  The next thing I noticed was that there doesn't seem to be be a way to link the produced data from the Omron to the AB, the Omron configuration software with the AB .eds files loaded only gave me the option to send data to the Omron which we do not need to do.  I created a generic Ethernet module in my RSLogix program for the Omron PLC and then created a consumed tag and linked that to the module but I do not see where I set up the link on the Omron side for that, so how does it know what addresses to read?? Any help would be greatly appreciated!!!! Thank you!

  10. Hello there. I have connected wireless module (master) to Vijeo Citect 7.4 using RS-485 to USB converter. My slave modules are supplied power from gird/generator and the master module is supplies from a UPS.    I'm reading Modbus registers of slaves modules data via wireless master. Every time we have a power failure from grid, I get #BAD from all slave addresses. The generator kicks off within 30 sec. That is the slaves are off for 30 sec. Even after the slaves are powered on, SCADA does not poll data from it until I restart the SCADA.    My current MODBUS parameters are:   Inittype = 3, TimeOut = 3000, WatchTime = 10, Retry = 2. Could you please assist me on which parameters to change in .ini so that SCADA reads Modbus registers of slave for more than 30 sec.   I tried increasing TimeOut to 30000 but it couldn't solve the problem. I would appreciate if some one could help me out.   Thanak you in advance.

  13. Modbus TCP Data Logging to Database

    gclshortt posted a topic in HMI & SCADA

    Here is a recent post that I would like to share. Using Visual Basic 2015 we will log three holding registers from the PLC along with time and date into a Microsoft Access Database. We will log every minute into the database with the information that we collect from the PLC via Modbus TCP (Ethernet). All code will be done and shown so you can implement this in your application with different parameters. The information collected in the database can then be distributed or analyzed in the future. Visual Basic 2015 will be used with the EasyModbusTCP client/server library for .net. We will communicate to an Automation Direct – Do-More PLC. Using the free simulation software of the PLC Designer Software, we will retrieve three values of the Modbus Holding Registers using Modbus TCP. Once we have this information out of the programmable logic controller it will be placed in a Microsoft Access (2010) Database. This will be done by using a SQL command to insert the data.

  14. Hi all,    Its the first time in this forum and need help about slc05/05 processor and modbus RS485. We need to link one slc05/05 with 5 power analysers and 3 vfd all with rs485 modbus rtu ports, as i now the slc05/05 have RS232 that suports Modbus, can we put an converter RS232 to RS485 and put slc05/05 to read write the power analyser's and vfd's. There are any sample / step by step tuturial with modbus and slc05/05 ?   Best regards, Jorge Cruz  

  15. CP1E MODBUS Maximum Slave

    innoaloe posted a topic in Omron

    Hello everyone, so I noticed in Omron's CP1E manual, there are no certain info on maximum number of Modbus Slaves that can be attached, however the PLC itself able to connect to slave number 1 - 247 I have read from common MODBUS specs, that 32 slaves are the limit for most MODBUS connections. However there are also statements that with proper design (1/8 transceivers) that we can extend number of connected slaves to 256. Anyone have experience or info about this with Omron PLC? Thanks in advance
  16. Thanks for any help.

  24. Program 16 position rotary selector switch

    michael.southerland posted a topic in CX-Programmer

    I have a 16 position rotary selector switch I'm trying to program to a CQM1 PLC, that I will also be programming to a micrologix 1200 in the future, using CX Programmer. The switch connects to the PLC using 4 inputs, and activates the inputs in a binary pattern 0-16 as I turn the switch. For example: if the switch is wired to the first four inputs of the PLC, and is turned to "9" 0.0 and 0.3 will be activated and 0.1 and 0.2 will not, just like binary 9 = 1001. I have tried several things trying to get the PLC to accept these inputs as a single "data-point," and then convert to BCD or Hex to use in a timer. I'm having no luck! Does anyone have any ideas how this is done? The switch is a Tosoku DPP01 015L20RCB, and because of the age of the PLC my instruction set is limited. Thank you in advance!
