  3. I am trying to connect an Advantys RIO island with a STBNIC2212 ethernet/IP to a Omron CJ2 PLC. I need an EDS-file for the Omron Network Configurator but the Advantys Configuration Software will only export to .xsy for NIC2212 (Ethernet/IP), only way to get an EDS is to substitute the NIC with a NDN2212 (DeviceNet), but I doubt that will work in the Omron Network Configurator. There is an EDS file on the SE-website, but it seems to be a different setup than my island. I thought ethernet/IP should be easy :( Any suggestions? Geir
  4. Hi all, I'm having an issue with EcoStructure Control Expert where when using DTM browser I try to connect but I get a message "No Ethernet/IP device at specified address...." My issue is that I had a device communicating using modbus but it has stopped and I cannot diagnosis the issue. I can ping the address and run a modbus poll from a PC on the network and everything performs correctly. Any help would be greatly appreciated. 
  5. Hi I am looking for a way to read and write data from PLC omron words, bits via FINS or EtherNet/IP protocol using python programming lang. Does anyone have any results in this? I really want to see your work, because all my attempts have failed. Thanks.
  6. Hi there! I've been working with NB HMIs with good result. But today I loaded a project to a NB7-TW01B and it feels slow, both offline and online. Switching screens and reading/writing take around 1sec or more. It first had some bmp images created with .bmp and .png files, so I tried using vector graphics instead, but didn't get any better. I don't have another NB to try it right now so I'd like to ask you if you've been in this same situation before or what could be causing this. PLC is CP1L and communication it's via Ethernet. Both devices are actually pretty close (cable is less than 3m) and the previous HMI (Pro-face GP) felt a lot faster. Thanks in advance!
  7. Need help in table scrolling

    Hi all, We have a DOP 107CV HMI we interface this HMI with microcontroller through RS485 Modbus protocol. I'm new to HMI and PLC's although we are successful in interfacing HMI with Controller(Communication Established successfully) We made a table in HMI and allotted some registers to Modbus address and data is transferred from controller to HMI up to this we are good in communicating Since the table created is static and we cannot scroll down from that table so, to overcome this problem we found History buffer and made PLC trigger and allotted address. In that History Buffer we created 7 rows and the data is sample whenever we triggered the PLC in that case scrolling is working fine, but the problem we are facing is whenever we update 3 rows out of 7 and triggered the PLC only 3 samples are updated in first column and in the next step we updated the other 4 rows and triggered the PLC the data is sampled on next column but we required it to be sample on first column instead of second.

  11. CJ1M+ETN21 Modbus TCP

    Hello. I'm trying to use Omron ETN21 as master for ModbusTCP protocol. I can communicate with 1 SLAVE UNIT (standard modbusTCP slave) using FB MTCP_ETN_Client.zip  from https://www.myomron.com/index.php?action=kb&article=1245. It works perfectly. But I have three SLAVE UNITS to communicate to. I'm trying to do this using [524]Modbus_TCP_FB.zip sample. I have copied SECTION1 to SECTION2 and changed IP number and SOCKET number. But this doesn't work. I would realy appriciate a working sample where OMRON PLC is MASTER for THREE (or more) SLAVES. I'm attaching code file... Thanks. Best regards, Andrej.

  12. Hello out there   I've searched for quite some time but unable to find any information helping me through this. I got a Omron PLC NX1P2 where im supposed to setup modbus communication over TCP/IP but so far i've only been able to find information regarding RTU setup. But seen forums mention its possible to setup via TCP/IP Anybody who can help. A program sample would be helpfull aswell. Im a trainee as automationengineer and this is my first encounter with Omron PLC and Modbus so quite new to the field.   kind regards Ivan T.
  13. Hello All, I would like to control Powerflex 525 drive with Omron NJ301-1200 PLC via Ethernet/IP (Set speed, start, stop). I've gotten until the part where I downloaded the necessary .eds files of the drive and imported into my Sysmac studio. However, I'm stuck after this point while assigning target variables and Originator variables and eventually setting speed and controlling the vfd. I've attached images for your reference.
  14. I am searching the RA Site, but thought a quick post might also yield some insight. I have a Version 17 ControlLogix L61 CPU with 1756-ENBT/A version 4 Ethernet Card. The system is dropping communications with it's SCADA System {Archestra Wonderware 2014 R2} I started by going to the ENBT Web Page and looking at statistics for a "smoking gun". I think I have found some things that might be worth investegating, but am not 100% sure of what they mean. The Diagnostic Overview shows 9/128 CIP Connections and 24/64 TCP Connections so nothing worrisome there. However, the Diagnostic Overview also shows CIP Conn Timeouts growing at the rate of 8 per minute.  - Possible Something!! The ethernet statistics page is where things start to get interesting.  In Errors and FCS Errors are growing at the rate of 4-6 per minute.  I have no Idea what an FCS error is? ANYONE? I'm wondering if I need to check the PLC program for some message instructions in error state?  
  15. I am currently trying to connect my OMRON NX1P2 1040DT1 (Using CIF-105) to my Unitronics V570 PLC, With my OMRON PLC as Master. It seems as if Unitonics Rs485 only wants a six-wire connection type but my OMRON PLC wants a 2-wire or 4-wire connection, Wondering if anyone has a solution to my problem and can assist me.  
  16. Hello, We have a FX3G connected to a FX3U-ENET-ADP inside a main cabinet. We are then using that master PLC to collect data from 2 other fx3g plcs in a node:node serial network. I was assigned a small project of pricing out some wireless adapters so we can upload/download to the two slave plcs. My question is, is it possible to upload/download programs to/from the slave plcs through the ENET adapter and serial network in the main plc? It would save us some money if possible. thanks.

  18. Hello, I'm trying to connect a CJ1M-ETN21 as slave Modbus TCP with a Modbus/Dali Gateway. I download from Omron website some FB with ones should be possible.   https://www.myomron.com/index.php?action=kb&article=1245 The FB only can be used with the direction unit 0, but we can change some directions inside the FB and can be adjusted to other units. In the download I found this FB: MTCP_ETN_Connect, MTCP_ETN_Fn01, MTCP_ETN_Fn02, MTCP_ETN_Fn03 .... Supposed with connect we can establish the connection with the master, but the FB never make nothing. Should I make some special configurations to use this FB? I appreciate any help. Thanks

  24. I have an open source library for Ethernet/IP and Modbus PLC communications.   It also support PCCC-type PLCs like PLC-5, SLC and MicroLogix via encapsulation in CIP/EIP (Ethernet/IP).   I just had a user let me know that they have a PLC-5/80 that apparently never got fully updated to support Ethernet/IP.   It appears to only support CSP (port 2222).  I have most of the code already, so I want to support CSP. I have a converted PLC-5/30 with a 1785 sidecar.   It shows open ports on port 2222 and 44818, but if I connect to port 2222 using Ron Gage's code, it immediately closes the connection.   I read somewhere (here? I think it was a comment from Ken Roach) that this was used to tell RSLinx to try the other protocol. I want to use some sort of PLC that "speaks" CSP in order to write up support for it in my library.   Is that something that I can do with my old PLC-5?  I looked around in RSLogix 5 to see if there was something obvious to re-enable CSP on my PLC-5 but I could not find anything.   Anyone have any pointers?  I might think about going on eBay to find some old hardware, but how could I even tell if something supports CSP?   Even a simulator would be fine.
  25. Error Indicator on FX3U-ENET-ADP

    Hi all, I have finished installing ethernet adapter module FX3U-ENET-ADP on the FX3U-48M PLC. From the ethernet module, i connected it to a wireless router and then i am planning of connecting to the ethernet module using GXWorks 2 on my laptop through wireless router. On the ethernet module, the error indicator LED is on (red). From the FX3U-ENET-ADP, it means that there might be setting or hardware errors.  I am asking if i have missed some steps on the installation process and if any of you have experience with similar problems. Thanks in advance for the answers.
