  1. CP1L Unknown IP

    Hello. I have CP1L EM30 with unknown IP. I have tried to use "Direct Ethernet Connection" with "Network Browser" but with no success. I have manually set the ethernet IP4 address to 192.168.20.20 / 255.255.255.0 I've got error: "The OMRON Ethernet Direct Connection Manager service is starting in Safe Mode because Windows APIPA is enabled. (0x82020003)Omron.Cxmw.Modules.SystemLibrary.SysLibException" The PLC does NOT have default ip 192.168.250.1. What Can I do? Please help. Thanks. BR, Andrej.  
  2. Hey! Is there any possibility to acces the PLC variables in GXWorks from another program? Like I want to read and write the I/O-s or Merkes in the Mitsubishi PLC from another program Could someone help me with this? Thank you!
  3. Hi all, First i apologise for my english, but it's not my main language. I am very new at this world so sorry if my question is too newbie but i have been for several hours trying to get some data from an Omrom NPX1P2 DT-100 using Ethernet/IP and now i am a bit desperate. I am trying to connect this PLC using a C# Library provided by steffan rossman and it seems to be very easy,  i can manage to connect it but every try i do to request data it fails. As i can see there are several ways to get the data, for example: In this example the function GetAttributeSinglec(ClassID, instanceID, attributeID) i need the ClassID, wich i don't know what is, the instanceID, i think in my case is 100, and the attributeID wich i don't know what is or where to define. If someone could help me about how to request data it will be very appreciated. Thx in advance    
  4. My HP laptop will lose communication with Mitsubishi PLC occasionally after removing ethernet cable to download from WiFi. Our company limits the ability to use the wi-fi when I have an ethernet cord connected to my laptop, it has to do with security. If I am connected to the Mitsubishi PLC, then want to download another file from our autosave, which we connect through the wifi, I have to remove the ethernet cord from my HP laptop to enable the ability to go wireless, however sometimes when I attempt to go online with the PLC after I re-connect my ethernet cable, GX developer will not allow it. I can ping the plc and even go online with other PLCs on the network, but for some reason, the one I was connected to will not connect. I restart my computer and even re-download the file again from autosave but no joy. Its not until an unknown amount of time that it will allow me to re- connect, its as if I lose the socket connection on the plc and it needs time to reopen. I talked to our IT department and they have no ideas. Thank you in advance for any help on this matter.
  5. Digital sealing

    Hi, I'm trying to figure out a way to make an automatic digital sealing for a NX-controller. Functionality: Each time I do a remote connect and/or change to the program on the PLC via VPN/Tosibox I want a counter to automatically increment. This counter is the digital sealing (checked by the authorities from time to time), and is displayed on a HMI. When the sealing breaks, the new value of the counter has to be reported. I've been thinking about incrementing the counter each time the Ethernet port on the PLC registers a rising edge on online establishment. But this will not work if there is a power failure (then the counter will increment unitented), or someone by mistake unplugs and replug the Ethernet cable. Antoher idea was to ping a specified IP-address, but there seems to be no PING-functionality. I've also been thinking about using some program data (i.e. last modified), but it seems there's no system variables on the PLC that contains this kind of information. Any ideas how to solve this in the PLC? Basically I want to know if the PLC program has been changed or if there a specified IP-address has been connected to the PLC-network.
  6. How to scan Ethernet/IP network?

    Scenario: You show up on site and the only knowns are Omron PLC and EtherNet/IP network. You have a laptop loaded with CX-One, an ethernet cable, and the ethernet port that is connected to a known EtherNet/IP Omron network (you can not see the PLC). I have previously worked with Siemens systems and used Primary Setup Tool and Proneta with wonderful results. Do similar tools exist for an Omron environment?  Question: How to (relatively quickly) scan an EtherNet/IP network for connected devices without knowing their ip addresses?  
  7. Have been able to exchange data types of BOOL, INT,  DINT & REAL between Omron NJ/NX CPU with Allen Bradley Logix CPU's with Ethernet/IP using the CIPUCMMRead & CIPUCMMWrite instructions. I now have a need to exchange "STRING" variable types. Have tried varions string lengths in the NJ without sucsess. AB default string length is 82 & Omron 256 but I think the difference is the length headder that AB has with within their String Tag type. I know I could convert my strings to an array of bytes & sent them this way, but was looking for a solution to sent them as native strings. Hope someone out there has done this & can share their leg work? 
  8. I would like to buy used ControlLogix PLC hardware to improve my own skills sets, can any one please suggest where i can buy the Controllogix hardware with full setup with software.My company name Excel Automation Solutions and Website is  https://www.excelautomationsolutions.com. 
  9. I am working on project where I need to program delta PLC to receive ASCII code from scanner. I anyone know how to program it helpls me alot.
  10. Hi all,   Is it possible to simulate LMC058 PLC with ethernet in soMachine software. I want to test the logic written in PLC which uses tcpudp library.
  11. I have a 2 CompactLogix PLCs running right now, communicating CIP Safety and Standard data over Ethernet I/P.  For reasons I can't explain right now, the IP address of the second one HAS TO change semi-randomly (the 1st PLC is static).  Setting the 2nd PLC's IP to static or assigning it a static DHCP address is the obvious solution, but for the purpose of this question, that cannot be done. Is there a way to programmatically change its IP address on the 1st PLC's program?  (There is an HMI attached to the 1st PLC and adding a screen to enter in the new address would be trivial.)  The only bit I'm still missing is how do I change the IP address on the module in the 1st PLC so that it's pointed at the right IP address of the 2nd one when it changes.    I found instructions on how to use msg instructions, but that hasn't worked yet.  Any help would be appreciated. Thanks!
  12. I have an Ethernet/IP bus and system including Ethernet/IP devices with CPU 1756-L81ES ControlLogix. PLC is connected to the switch. Bus is built from the switch as a line. Can I connect the last device on the bus back to switch again? In thes case bus will be ring. Do I get problems with connection it this way. Switch is Stratix 2500, which is lightly managed switch. I believe it will increase the traffic in the bus.
  13. Omron PLC Python communication

    Hello All,    I am college graduate student and I know little bit of cx-programmer for modifying existing program. I have master CJ2M CPU34 PLC connected with three CP1L PLC. All 4 PLC are connected via hub through Ethernet cable. I want to read/write some memory data to/from PLC through Python programming. As I am new to PLC and Python I have not much idea regarding omron PLC and python communication. So is it possible to connect python with master/slave PLCs directly? If yes then how can I communicate? I was trying with cpppo library to connect with PLC but I could not connect it.  I have attached the master PLC communication setup for the reference.    Any kind of lead/help is appreciated.    Thank you in advance.    -Yash
  14. HOW CAN I USE NETWORK I/O ON LADDER SOFTCOMFORT?

    Hi! I was doing an project using function block, but at one point it became too complex to use FBD so I would like to use ladder.  I'm using an ihm and that's why some inputs are of the network type, in FBD, it's easy to use the network i/o, but in ladder, the network inputs, where I receive data from the ihm, don't have outputs for me carry out the logic. How can i do this? USING FBD USING LADDER As you can see, theres no output on network analog input, on the digital to!

  16. Is there any way to monitor ethernet/ip bus, states or faults and to make an alarm to the panel alarmlist. I am using IO-stations (1734-AENTR) and I would like to monitor somehow the system. I feel that reading the slot status of the 1734-AENTR device is not enough, because it is not possible to monitor all the cards in a slot. How to get alarm on a screen if I lose any station on the ethernet/ip bus?
  17. I have a PLC 5 program that is acting as a master controller for several other various PLCs.  I have found where an input is coming in off of ControlNet.  I went to the relevant ControlLogix program but I cannot find where this output is being written to.  I am fairly new to Rockwell as I have come from a Melsec background.  Any help would be appreciated.
  18. Hi, I have the following configuration where 4 PLC panels, with each having a Q12PH CPU and QJ71E71-100 module. All these QJ71E71-100 are connected to a HUB using straight cable. From the HUB one connection is going to an I-Fix SCADA which is already communicating with all 4 PLCs using MC protocol. I want to send data from 3 of this PLCs to the 4th PLC in the same network using fixed buffer communication. Can anyone provide a sample program for the same. Send and Receive side. I am using GX Works 2 for programming. Your help is very much appreciated.
  19. Ran into this unique little "bug" today. Tag Variable is INT , Tag Output is REAL  Using CPT Instruction  (Variable / 2000) * 700 results in an output of Zero (0.0). Using CPT Instruction (700.0/2000.0)*Variable results in a non-zero Real Number (350.0 for example if Variable = 1000) Turns out reading the help, that CPT does math in the type of the first variable encountered and then converts to the destination type. Thus 1000/2000 in Integer Math = 0 and 0 times 700 equals 0 which converts to 0.0 Sharing just cause I'd never hit this "bug" before.
  20. MPI Connection problem

    Hi there. Recently I've experienced problems when connecting to a S7-300 PLC via MPI/PROFIBUS. I use a PG with CP5711 processor. The thing is that I'm able to connect when I plug the 6ES7901-0BF00-0AA0 cable (male to male) directly to the PLC connector, but when I try to do connect to a PLC that has any device connected to the DP port (let´s say an inverter or HMI) I get 33:17075 error. PG/PC Interface it's correct, in fact another PG with the same configuration is able to connect through the already connected DP device's cable. Station number and transmission rate is all correct.  So I tried the Simatic NET Diagnostics Test and I got error 0x0313 and since the mentioned parameters are correct I refered to this link:  How do Diagnostics and Remedy work in STEP 7 when an online connection with the CP... - ID: 11492532 - Industry Support Siemens Where they say the following:    I've searched for this readme file but can't find it, and there are no useful results when looking for it on internet.  Why am I able to connect directly to the PLC but not when another device is connected and I have to use the female connector of the DP connector itself? Should I try to reinstall CP5711 drivers? According to Windows, I got the last drivers for the CP.    Thanks in advance and I hope you can help me!

  25. This is a 1756-IF8 rev 1.5 Analog Input module. This has happened a couple times where the Module Input Data, (not mapped), goes to the high limit and freezes (Data Monitor data is static).  Plant operators pointed out the trending wasn't accurate. There is no fault on the module, no yellow triangle on the system tree for the module.  The Module properties show no faults, and RUNNING. I have done a "Reset Module" both times, (Module Properties - Module Info tab), while monitoring the module data.  As soon as it resets, instantly the Data Monitor starts showing live data. I'm going to try and replace the module at first, but I have some concerns. Has anyone run into this before? I can't seem to find any information on the "Reset Module" animation, and what it actually does.  Any information, (or where to look), would be appreciated. I don't like to hot swap, but I believe I will need to in this case, (utility).  Will the current properties, e.g. scaling transfer to the new module? Thanks Dave Redman
