Programmatically Change IP address of Target Module
ProgLogConfuser posted a topic in Allen Bradley / Rockwell Automation
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! -
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. -
Hallo, i want to connect PLC Omron CP1E to indicator weighing scale with modbusRTU connection and i have a CP1W-CIF11 module to connect indicator with CP1E. ,but I have no experience in RTU modbus communication in the PLC. How do i start? *i just need output: 1. Coil (Reference No = 0. Output bits) for input switch with address 3 (Tare). 2.Input Status (Reference No = 1) for output lamp with address 17 (stable) 3.Input register (Reference No = 3) to read data with address 5 (gross weight) 4. holding register (Reference No = 4) to write comparison data with address 17(over) page 85 - 94 in attachment ad4402_manual.pdf

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?

Has anyone successfully used a 1783-NATR for Modbus TCP communication between a ProSoft MNET card (in the ControlLogix rack) and a Modicon Quantum? ProSoft MNET: 10.x.y.z Modicon Quantum: 192.168.1.x There is one (1) ProSoft MNET and four (4) Modicon Quantum's. NOTE: I know there are other devices that support this behavior...the NATR is the suggested standard hardware. We are getting various responses from distribution and support. ...I was hoping someone in the community could confirm. Thanks for your time!

Hi I'm trying to set up Modbus RTU communication between FX3U PLC and a weigh module. I would use the ADPRW command using 0X03 to read the 16 bit Holding Register but in the weigh module the Data Address/Holding Register of the value I want to get is 400047 - 400048. How to translate the value in 16 bit? Thanks, Fabio

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, we have a Mitsubishi PLC Fx3U-128MT and a A&D weighing module AD 4212L. The weighing module supports MODBUS RTU communication via RS-485. We are looking for the most affordable and simpler way to establish communication between PLC and weighing module. At pag 20 of the manual " MODBUS Serial Communication Edition " https://dl.mitsubishielectric.com/dl/fa/document/manual/plc_fx/jy997d26201/jy997d26201g.pdf there are three options of communication equipment. According to your experience, what specific interfaces do you suggest us to invest in? Thanks

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 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.

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!

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.

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.

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.

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?
