RS 232C Serial Communication between Magelis HMIGXU3512 and Omron PLC CP1E
Klauzer posted a topic in CX-Programmer
Hello. I am trying to make a serial RS 232C connection between Schneider Magelis HMIGXU3512 and Omron PLC CP1E. However, there seems to be a communication problems between both of the equipment. I am using cable XBT Z9740 for the serial communication cable. The format used is 8.2.N for both equipment. The baud rate is 115200. No Flow Rate is choose. Anyone can help with this kind of problems? -
I'm working on a project with Omron CP1E-N30DR-A Plc (And yes it does have the timeclock) And Omron NB7W-TW00B HMI I'm trying to use the Clock adjustment DATE(735) feature in the Plc program. In conjunction with the HMI to correct the time. Only focused on the Plc program for now. And presume I can accomplish the HMI portion once Plc program is working. Been fumbling with the Instruction manual descriptions several days and seems I'm not getting anywhere. Is there a possibilty to find an example program for this feature somewhere online? Or could someone possibly create an example program? I realize I might have missed some key information things in this topic. But lets see if I get any response at all.

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.

Hello, From modbus, Im reading a HEX variable in the data register D0, as it is a 32 bit variable, the second part is saved in D1, then I get: D0: BE62 D1: 31D7 The value that I should obtain in float is -0.2208932 as I obtained setting BE6231D7 in online Hex to float converter and this agree with what I'm reading on the flowmeter. The problem is that when I try to change the data type from channel to Real on CX programmer I obtain a different value, also the registers are not sort in the proper way, instead they are sort inversely 31D7BE62, and obviusly the obtained value is completely different. Also instead of Hex, I want to display the decimal, or floating value, is there a way to do this? I'll attach some captures.

Please could you assist with the software required to download data tables from 4 off DIRIS A10 Multifunction Meters into TM221CE40R Logic Controller via TMC2SL1 Comms Cartridge using Modbus Protocol over RS485. I have downloaded the Modbus tables from Socomec but not sure how to get these into the PLC. I would really appreciate your help in achieving this. I am using EcoStruxure Machine Expert - Basic to program the PLC & DAQ Factory Developer Release for my Touchscreen. Link to Socomec Modbus tables: https://www.socomec.com/files/live/sites/systemsite/files/SCP/6_gestion_energie/diris/diris_a10/DIRIS-A-10_COMMUNICATION-TABLE_2018-01_DCG01013_MULTI.html#General

Hello, I have been so many days trying to comunicate the multiway software trought a serial usb converter with the SCU31 device, using a omron function block to read a holding register, but I can't achieved it. Now Im receiving some frames on multiway, but there is always some errors. I was wondering if somebody in here that have worked previously with modbus and omron can be able to help me in how to configure everything corectly to be able to read the value from multiway, on the plc, and where is this value saved. I'll upload some captures to show what I have done till now.

How can I read a variable trought Modbus on the PC? RS485 Modbus and Omron
alpr_94 posted a topic in CX-Programmer
Hello, I have been reading some post on this forum about Modbus and omron, but it has been complicated for me communicate an Omron PLC and a computer just to test the Modbus communication. I have a PLC OMRON CJ2M-CPU32 20K with a CJ1WSCU31-V1 that I want to communicate trough Modbus first with a computer just to test that is everything working ok. How can I do that? How do I need to configure the units, switch? Nodes? Im using multiway, and CX programmer, I already downloaded Macro Protocol to the PLC, but by now the only thing that I get is RD1 flashing when Modbus poll software is active on the computer, but this software says timeout, and don’t receive packets… I have used the easymodbus excel file to create the code to communicate the PLC, but as I see isn’t working. Does somebody in here have got to connect a plc to the computer with this easy modbus file? How is the proper way to use it? Or there is a better way to use Modbus in Omron? I’m really desperate. -
Which is the best procedure to reset a SFC finite state machine
paulovedder posted a topic in CX-Programmer
Hello, One thing that I constantly find hard to do when I program in SFC is to properly reset a FSM. If something goes wrong during the process I like to be able to reset the program. In Ladder this is quite simple to accomplish. Usually, I have a variable (non volatile) which is responsible for the step transition. If I want to reset the FSM I just use the function MOV to disable every step variable, which turn off the entire FSM. If I want to restart the program I use the MOV function again to enable only the first step. So my question is: how can we accomplish that in a SFC program? Lets not consider the option of having a reset transition in each step... Best regards, Paulo -
M241 - Modbus TCP - problema reading analog inputs (#300001)
horvatmiha posted a topic in Modicon / Telemecanique / Schneider Electric
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! -
I have omron plc CJ2M CPU15 and I have input module CJ1W-MD261 (32 inputs, 32 outputs) and I was wondering can I MD261 module for hsc inputs? When I open CX programmer and go to settings and go to "IO Module" I see that I can include HSC input and I assigned it to Input 08 and what is that input? Is that input 0.08 on MD261 because my plc has no integrated inputs or outputs (image included at the bottom). Any help is wellcome

Hi all, I am trying to update the firmware of a NS12-TS01B-V2. I have downloaded the RecoverUpdate_8_95.exe (and someothers) from the myomron website. I have followed the instrucctions PDF, but when I switch on the HMI with the Compact Flash inserted, nothing happens: the screen is dark and the led is lit orange (not blinking). The compact flash is 1GB (not omron) and formated using a CJ2. I have been using this card in OMRON PLCs and HMIs for years without problems. I read in other topic than I guy had similar problems and he solved it using other computer and other unzipper program. I have tried it, but it did not work. After that, I tried to update it using the DIP switches, but I got more problems, because I got a Warning first, and later an Error, because I forced the installation of the Firmware of the NS8 (BANK1) instead of the NS12. However, the other BANK folder contains the FW for the NS5... Anyway, I could fix this error because previously I did a backup of the already installed system (V7.0). I would like to ask you to send me a BackUp of another NS12, using the "Manual Transfer", that should works. I need the 8.20 version or higher. Thanks a lot. My email is hector.moreno.lax@gmail.com

How do I edit an array size ARRAY[0..13] OF REAL to ARRAY[0..15] OF REAL? Sysmac Studio doesn't allow it to be done online, as far as I can see. If I do it offline and then go online and Synchronise, Transfer to Controller I receive error Any ideas?

Is it possible to view the values / states of all inputs, outputs and workbits (e.g. 64.00 through 64.15 on Omron CQM1 PLC) on a single screen or control panel within CX-Programmer software? I'm trying to troubleshoot some ladder logic that I wrote and need to know the values of 5 or 6 inputs/outputs/workbits simultaneously. Having to scroll up and down through my ladder logic repeatedly does not work well with code that changes state every 5-10 seconds or so. Any help is welcome.

Hello, I have a PLC NX102-9020 with an NX-CIF105 card. I need to communicate with 3 CQM1H, with Host Link protocol. Someone could tell me how to do it or if you have an example. The frames to send I already have defined and tested, I just need to implement it in the PLC. Sorry for the translation, it's done with Google. Thanks

I have got a FX3U-16M and -32M PLC and trying to connect with Moxa NPort 5130A serial device server to work with a scada. It seems that i dont get the modbus to communicate. I have tried the 110 ohm, 330 ohm and open setting on the device. I am making use of a 2 wire system. I have configured both the channel 1 and channel 2 of the PLC to work with MODBUS 485. i have written a program like follow M8411 ----------- Move H1087 D8400 ----------- Move H1 D8401 ----------- Move K2000 D8409 ----------- Move K400 D8410 ----------- Move K10 D8411 ----------- Move K3 D8412 ----------- Move H1 D8415 ----------- Move K100 D8416 I just need to test if there is communication from these cards. i have got 15 cards to test. Any other help will also be appreciated.

Trying to connect our old Sysmac C200HE PLC to the CX-Programmer software however, failed connection appears. We are using a USB-Serial connection and have set up the comms on the device manager. To try and connect to the PLC we are using the Auto connect function, selecting the usb-serial connection and selecting the comms the same as the host network. Any help would be greatly appreciated.

hello I have been forced to replace a TWDLMDA20DRT with a Schneider TM221ME16R. the plc is a slave but I am having trouble getting the Modbus data exchange to work like it did with the old plc. I have setup the serial port to use Modbus etc etc and I played about with the read_var FB but this wasn't required in the old plc so im confused as to why I would need to use it on the replacement. I have come across another FB send receive message but again i'm not too sure if this is required. the master plc uses the msg2 and exch2 command. I believe I am just missing something very simple here. Lighting Panel - Old_PLC.twd Lighting Panel1 - Master -.twd Lighting Panel - Pillar5 -.smbp

Hi, I'm using a CJ2M CPU 33, and also a CJ1m Ad-041-V1 Analog Input and DA-041 Analog Output card. I am using the Analog input to measure my current in my one heating application and Ihave that reading and scaled correctly, but now I want to use my Analog output to replace the Rheostat we have in the system. I'm having some issues setting the range and getting voltage to vary. I also am a little new to Analog Outputs and don't know what I'm doing wrong. I have attached my program here. Any help would be greatly appreciated. Analog Heat.cxp

HI , Thanks a lot for the reply & help on previous topic. Now i setting up a new system with 2x CJ2M CPU13 and 2x SCU32 and the connection via 1000M RS485 cable. May i know the best communication to use for the serial communications? Regards, TJ SHARON.

To all the gurus. We have a project now that is using CJ2M PLC. However some hardware is using 1 piece of ETN21 card while some machines are using 2 cards. Programs sequence is quite similar. However Customer wants us to be able from program side able to detect if there is 1 card presence or 2 cards presence. Not sure if there is certain bits or memory in PLC that program can tap to "detect" number of cards that is presence.
