Ethernet/IP bus line topology to ring.
Jiggadoo posted a topic in Allen Bradley / Rockwell Automation
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. -
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

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!

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?

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.

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!

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

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!

Hey Everyone, My company decided to purchase a piece of equipment from China, and I have the pleasure of updating its terrible existing controls. We were given the PLC program by the manufacturer, so I was able to make my changes pretty easily - or at least that would be the case if I could actually connect to the dang thing. The source program is indeed openable and editable via GX developer (the original configuration shows it as an FX3). I figured connecting should be straightforward, but I was wrong. I initially used a serial/usb converter that I've used on some older Allen Bradley equipment (which worked fine for that). However, after no luck using it on the "Mitsubishi", I purchased a different cable that I found recommended on this forum (Tripp Lite USA-19HS - https://www.alliedelec.com/product/tripp-lite/usa-19hs/70101537/?gclid=Cj0KCQiAj9iBBhCJARIsAE9qRtB_n8TVAnJdFyYokoEu42W6H6LaT4kVsgJQI1qvPUsUF3rFviKpbt0aApLHEALw_wcB&gclsrc=aw.ds). Still, no luck. I've tried 7E1 and every baud rate possible, as well as some other bit/parity configurations (and yes, I've verified that I'm using the right com port, as well as tried moving the converter to different ports and trying those). Nothing seems to go through. I have almost no experience with Mitsubishi beyond a couple of FX5s (which have worked fine, but I connect to those via ethernet). Any help would be greatly appreciated; if I can't make these changes, I'm going to end up rebuilding the whole cabinet with a PLC I can rely on. Thanks in advance.

Hi guys, i got some problem when connecting to ethernet modules to 1 virtual computer. My virtual computer has IP (11.20.103...) my 1st ethernet has IP (11.20.52...) and my 2nd ethernet has IP (11.20.96...) i can connect the 1st ethernet to virtual computer with mx component, but i cant do that with second ethernet module. Are 1 virtual computer just can connect to 1 etherner? Or the third IP must same each other? Can anyone help me Thank you

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?

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.

I have a Siemens HMI 6AV2 124-0MC01-0AX0 in my machine. I want to clone the display on the HMI to PC/Laptop. My question is: 1. What software that I need for this task? 2. What kind of interface that I need between the HMI and PC/Laptop (for example ethernet cable, etc)? 3. Do I need to communicate with PLC connected with HMI or can I just connect with the HMI? Thanks in advance for the answer.

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.

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.

Hi all, I want to ask some questions regarding Ethernet Communication with FX3U PLC series. I have 2 PLCs of FX3U series (FX3U-48M and FX3U-64M) and I want to monitor its data (input and output) using ethernet communication in real time. My questions are: 1. Does FX3U PLC have ethernet port so I can connect it directly to my Laptop/PC? 2. If no, do I need to use FX3U-ENET-ADP and can it be used for 2 PLC or only 1? 3. What software do I need to use to configure the communication between PLC and FX3U-ENET-ADP? 4. Does this configuration change the existing PLC program? 5. Can i transmit the data wireless-ly using some kind of ethernet to wifi adapter and what additional hardware do i need for that?
