  1. Hello there, Today i have commissioned my first project with OMRON make PLC. Model: CP1L-EM40DT1D. (CX-Programmer) I have 2 built in 0-10V Analog Inputs on the plc. for analog input no-1 i get the digital value of 0-1000 in specific plc register address corresponding the 0-10V. (Factory setup) But today on site, i have noticed that some miner value of 0 to 50 is always coming and fluctuating very fast in that register, however the transmitter are genetaring 0.0V only (I have checked using digital multimeter with high precision) PLC and Transmitter are already grounded and all the cable connections are tight as well. so how to overcome this high fluctuating value ? is there any setting to filter the input ?
  2. Need help for FBD programming

    Good Day. Someone could help me to convert following ST code to FBD? I can make a program in ST language. I am trying to figure out how FBD works.  IF Var_1 THEN Var_2:=true; Var_1:=false; END_IF; IF Var_3 THEN Var_2:=False; Var_3:=false; END_IF;     Note: Var_1 and Var_3 are controlling from PC through Modbus TCP. 
  3. This is a bizarre one... CompactLogix, 1769-IF8 with 1492-AIFM8-F-5 wiring system. My client has reported several instances where one of his flow rate displays is frozen at its maximum value.  Each time, I have gone to the site, found that the value in the analog input tag is at full scale, and measured more than 20mA at the input - as much as 28mA!  I measure it using a clamp-on meter and I measure it at the input module (1769-IF8) and the external, pre-wired terminal block (1492-AIFM8-F-5).  I cycle power to the PLC.  No change.  I cycle power on the transmitting device.  No change.  I disconnect and reconnect the input (signal wire at the module or the terminal block) and everything goes back to normal.  This has happened on multiple channels on multiple input modules and with two different types of transmitters. I didn't install this system, but it seems to have been done properly and it had been running fine for many years.  These problems just started happening out of the blue. Has anyone out there had any similar experience?  This is a new one for me after more than 25 years in the business.

  5. Analog Input Addressing

    Hello Everyone, This is first time i am using Omron's CX-Programmer. PLC-  CP1L-EM40DT1-D I have 2 built in analog input of 0-10V on PLC Board. I want to know the default resolution, Data Type and Register address to detect analog Input for my further programming. Please Help me with these...
  6. Hi! I have a question about programming. I want to place an input (X01) on the left vertical line, to allow the rest of the program running by an external switch. How can I place an input like that? I work on Gx works2 and using an Fx3g Plc (I used it once, but i can't find that program.)
  7. Hi there, is there anybody who use macro function in NB designer? I need list of C language syntax who can be applicable in macro. I have a task to migration from NP designer to NB designer who use different languages. Thank you
  8. Hello! I am new at programing PLCs. I am using TM241CE24R PLC with TM3AI4 analog input module. I can successfully read temperature from 4-20 mA sensor. I want to communicate with my PC (SCADA) via Modbus TCP. For testing purposes I am using CAS Modbus Scanner. I can read digital inputs, coils and holding registers successfully. Problem is that I can't read analog inputs (#300001 etc.).  I have nothing defined in GVL list. Is this causing problem? I also don't have any Modbus TCP Slave device in Ethernet_1. But how can be all the other registers read successfully?  Please take a look at screenshots below. Also check Error message from CAS Modbus Scanner. Where is problem? Please help. Thanks in advance!

  10. Hi new to the forum, and first post, however, I have found an abundance of great information here, so I was hoping someone might able to help me with an issue.   PLC is BRX BX-DME1-10ED13-D I am trying to read an analog output from a sensor that is capable of essentially outputting a mA signal proportional to where a printed line, or contrasting edge is at in its field of view. It is used for web guiding applications to make sure the web is tracking straight, so you can identify if the line or edge is moving to one direction or the other, and correct the web with an articulating web guide. I have attached the diagram for the sensor, but I cannot for the life of me figure out 2 things 1) The power supply to the sensor is listed as follows Supply current - From fife control +/- 12vdc 50ma (+)12vdc  AND   - 40ma (- )12vdc how do you provide both (+) and( -) 12VDC for the supply power to a sensor- 2 power supplies with the the opposite polarities grounded on each?   2) The outputs are listed as "Sum" and "Differential" so apparently there are two outputs, i dont know if anyone has come across these terms relative to sensors before, but I am trying to sort these out. According to the OEM  Sensor Output Range   -20 mA to +20 mA for line guiding     -20 mA to +10 mA for edge Guiding   I have attached the pin out diagram as well as the sensor spec sheet, but I am curious to see if anyone might have insight as to how I would get an analog input reading from this configuration? Thank you in advance for any help!     224615.pdf SE-26B Product Sheet.pdf

  13. I have a Modicon NOM0200 unit connected to an access switch to send commands to various rs-232 devices. The Access switch requires a "disconnect string" to end communication with a particular port. The disconnect string is "CRTL+D", how can I send a "CRTL" keystroke from the NOM0200 unit? I know for carriage return it is "$R" is their a similar combination I can enter for "CTRL"?  
  14. FX3U Analog Programming

    Hi,  Anyone can help how to program a analog coming from a level transmitter? I have 8 analog inputs (2 unit of FX3U-4AD) to be read out into the plc program. how can this be possible. I'm new to mitsubishi analog. it is different from my experience(using siemens before).   Hope someone can help.   Thanks!!!   Marky
  15. I am trying to program an analogue output on a Siemens S7-1500 unit from a 4-20ma sourced analogue input scaled over 0-250 degrees. The analogue input will have an adjustable setting in the software for when the alarm status should occur and at this point I want the analogue alarm output to start to process at 4ma, at 5 degrees above the initial set point I want the analogue output value to be 20ma I have no idea how to do this so any help from people is greatly appreciated and advice on which analogue output card to use would be helpful.  
  16. HI I'm using PlC5/20 when I click on setup screen on the BTR block (to view the analog input configuration) i find the following message: No modules exist in the IOconfiguration for this R/G/M however the analog input signals is running properly....i just want enter the setup screen for configuration. I'm assuming that I need to enter I/O module in the I/O configuration? Can I do this without taking PLC to Program mode?

  21. hi really i  need the help from someone  i dont have any idea about the step to  a project  i wish to someone support me and help step by step  radouan_2020@hotmail.com
  22. Hi guys. I have a new SRM50-HAV0-K01 sick encoder for my ELAU servo motor (model: ELAU sm 070-60-010-P0-45-M1-B0), and need to program it according to an old one (which seemingly is broken) via hiperface. device: PGT-11-S LAN software: SOPAS 2018.3 build 4.1.1.324 (Vm version 1.8.0_73) I tried to find any certain way for programming of sick encoders on the net using the mentioned device and software, but cant. all is only about datasheet or how to use teh software without an specific instruction. I am not even sure of that the old one is broken, except that in the analysis mode of the SOPAS (entering via hiperface) I can see the the  sin-cosin graph out of its limitation line. The thing is I have bought a special tool which has not any specific instruction and SICK group does not reply any exact instruction for my issue. Here is my questions:   How can I program the new encoder just according the old one?   And how can I assure that the new one programmed just as the old one?    and what is the definite sign of a broken encoder?   anyone experienced?
  23. A1S68DAV parameter

    please can anyone tell me how to set A1S68DAV analog output module parameters , such as voltage output and resolution? or is the parameter can't be set at aLL (ie, fixed at -10V to 10V)?
  24. Direct Logic 05 Ethernet

    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
  25. 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.
