  1. Good day,   Does anybody know if one can connect multiple micro 800 PLC's to each other via GSM?
  2. Hi All need to convert a Decimal Value into Ascii code to send out on serial 485. eg. Weight comes in as Int 12345 i need to send it out in Ascii as 23 32 20 31 32 33 34 35. I have created an array 0 of 8 (Word) DB. Is there an easy way split the int into Digits convet in into HEX and slot the value into the various array positions? Array 0 of 8 = 23 means # Array 1 of 8 = 32 means 2 (Station ID) Array 2 of 8 = 20 means Space Array 3 of 8 = 31 means 1 Array 4 of 8  = 32 means 2 Array 5 of 8 = 33 means 3 Array 6 of 8 = 34 means 4 Array 7 of 8 = 35 means 5 Array 8 of 8 = D means CR    this sends the value of 12345 to Display ID 2 . need help to convert the decimal number in ascii. the decimal number will be max of 5 digits and less than 32000   any help will be greatly appreciated.

  4. Hey all - I am working on a car wash system design that will utilize the Nayax payment system. Has anyone utilized them? How do I incorporate the device with PLC to automate the system. After payment is approved how can I send out that signal from them, all via ethernet on a managed switch w/ wifi for exterior comms for the Nayax.
  5. Hello! I have one Controlllogix project that communicates with a modbus slave through modbus TCP, using a Prosoft module model MVI56-MNETR. Does anyone know what happens to the data polled in case the network fails? Do all variables go to zero or do they freeze in their last value (or something else entirely)? I couldn't find anything in the Prosoft manual. Thanks for any help!
  6. Hello There I need to set up communication PLC to PLC ( R08CPU to Fx5CPU) but i dont have the modbus library for  the R08  Does anyone have the library? or where can i get it? thank you.

  9. i am trying to communication my weintek HMI with Siemens Energy Meter PAC3200. I am using MODBUS TCP/IP Protocol but i am unable to read the data register of my energy meter. Somehow i got to read the 32bit data register but still unable to read the 64bit data register of my total KWHr Energy consumption. I have also attached the manual of my energy meter. Please guide how to read all the data registers of that energy meter. Please see the page 40 onwards for reference. The manual the about 7MB so i cannot attach the file. https://support.industry.siemens.com/cs/attachments/26504150/A5E01168664B-04_EN-US_122016_201612221316360495.pdf

  11. Hi all, after my complaing about my lack of network access in the workshop ive been tasked with fixing this so ive have some general questions about networking and concerning Ewons so this network will be used for connecting ewons to test products as well as general computer access the plan is to have 7 computer access points as well as 2 points to connect to product lines for testing my intial thoughts were to run 2 cables from our network to 2 routers, 4 computer access points and one line testing connection on 1 and 3 computer access points and one line testing connection on the other so first question is what type of ethernet cable should i use? i assume cat5 is fine, is it worth going for cat6 or is it just a waste of money? and should i be running crossover cable or straight through? do i need any specific routers or will anything do? will i be able to add splitters later down the line and be fine? or should i future proof a bit with more robust routers? my years of avoiding networking at uni has come back to haunt me i know the basics but thats all really thanks to anyone who can offer some usefull information i mention the Ewon units because ive been told that they need to be the only one on their connection to the network, although i dont know how true this is  
  12. Modbus fonction block error

    Hi everyone, first time posting here. I've got a problem with the Modbus MTCP-CP1L-Server fonction block. it worked fine for a good amount of time until i try to change an ethernet switch (not managed) on my network. at this moment the fonction block started to give me an error code (2211 ''unit is busy, can't execute''). So i put the old switch back again and I called Omron and they tell me to download Etherway and try to send some data to it but they can't do more. I did and BAM, it worked again. everything was fine for about a week and i was like, okay if etherway can ''solve my problem with the fonction block, i can put the new switch again, No I can't. It give me the same error, I try'd so many thing( put the old switch, everything that was possible in Etherway, change IP address, ethernet setting, reboot everything, connecting the unit direct to my PC. nothing can erase that error.  Unit is an CP1L-EM with built-in Ethernet port did someone had have the same problem, or have any idea that can help me ? thank. Sorry for my poor English, its not my first language.

  15. Delta DVP12SE Modbus TCP Help

    I requested support on getting my DVP to talk to Factory IO for some cost-effective programming experience but the DVP is really poorly documented. The below wording and 2 pictures were all the support I got as I am not a business. The M codes are not listed in the ISPSoft help file and hard to track down, combined with things like "After the reception of the command is complete, bit8 in D1395 is ON" and then if I am reading input registers and holding coils but saving to a D word register how the heck do I convert the data into a useable boolean format for logic use??!! I have no been able to even get the DVP to read or write ANYTHING but I can use a modbus program to turn on the DVP's bits no problem so I know communication works. eg: F05 H500 will toggle coil Y0. The issue is when I try and use the DVP as the modbus client. From my laptop I can use these commands to modify Factory IO which is running as modbus server Slave ID 1: F02 H0000 H0009 (Read inputs 0 to 9) Tx: 00 02 00 00 00 06 01 02 00 00 00 0A, Rx: 00 02 00 00 00 05 01 02 02 C0 00 (In put 6 & 7 are on) F15 H0000 H0009 (force coils 0 to 9) Tx: 00 0F 00 00 00 09 01 0F 00 00 00 0A 02 00 00, Rx: 00 0F 00 00 00 06 01 0F 00 00 00 0A   But how the heck do I format the LD program to actually do those commands?

  16. Omron rs485 communication

    I am using OMRON CJ2M-CPU15 with SCU41-V1 communication module I want to establish communication (rs485 modbus) between omron and Schneider device for reading out electrical parameters. How I can do this? I could not find any manuals and this is becoming very hard for me. I want simply to read few registers from Schneider. Where do I set unit number, starting register, ending register, number of data? I was recently using Siemens and Unitronix and started working with Omron recenlty. Do you have any examples or manuals for this? Thanks in advance
  17. Network Dropouts at Night!

    We have been having a re-occurring issue where some of our PLC's throughout our plant have a network outage that occurs around the same time every night. The PLC's are disbursed among the plant and it has been confirmed no large pieces of equipment are being turned on around this time every night... The network traffic does not fluctuate around this time and is not near a "troubling" level. There was a reboot to one of our servers on the same VLAN as the PLC's that are having the connectivity issues... What could have changed from a server reboot to remedy this issue, the server is not communicating to the PLC's, they are just on the same VLAN.

  19. 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.
  20. 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.    
  21. 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.

  22. 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.    
  23.  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.   
  24. Network Number Problem

    Hi,  I am trying to connect a new CJ2M-CPU31 to a used NS12-TS01B-V2 (it seems to be restored to default). I want to connect that using Ethernet.  In the Cx-Designer I have set the following for the NS ethernet Port:   - Ethernet: Enable   - Net number: 1   - Node number: 5   - UDP Port: 9600   - IP address: 192.168.140.5  //  255.255.255.0  //  0.0.0.0  //  0.0.0.0 And the following for the host:   - Name: CPU_A   - Type: SYSMAC-CJ2   - Protocol: Ethernet/IP   - IP Address: 192.168.140.10 In the Cx-Programmer I have set the same IP address for the PLC from the I/O table configuration.  However, they are not connecting. After some seconds the HMI shows a Time-out Error. I am used to works with this kind of HMI, I think the problem is in the PLC because this is my first time working with a new, out of the box, PLC. I have tried to comunicate them using the "Com. Test" tool from the System Menus of the HMI; however, I didnt get it.  I think the problem is than the integrated ethernet port of the PLC is not in the Net Number 1. I have tried to set it using Cx-Integrator. I have clicked in "Create routing tables" -> "Insert SIO CPU unit" for the Unit250(Integrated Ethernet Port) -> Local network number = 1 -> Transfer to PLC. Nevertheles, the windows "Online Connection Info" is allways showing Net(-) instead of Net(1):    "Ethetnet [CJ2M-EIP21] Net(-), Node (10),  Unit (0)" I have checked the Cx-Integrator Manual and says in this case it is only neccessary to "Connect", but I have tried it, waited for the 254 nodes, and... it doesn't work!! I don't know what to do! Thank you.
  25. 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!
