Hi Everyone! Where are my experts? I am undertaking a project at work. The project contains analog style motor positioning circuits (operational amplifiers, integrators, and other PI elements). Not that this is relevant to the post yet ;) .It's my first PLC project ever! I am using the Schneider M258 with SoMachine 4.1 The PLC is talking to SoMachine via Ethernet (obviously I have a router between the PLC and my pc).I can Login and run the first POU I created. It's a simple And logic circuit for now. I have a co worker (c programmer) agreeing to help me pass data from my PLC to a browser screen. Although he's not familiar with PLC he's quite skilled writing code. He has wrote a Modbus protocol which allows him to interpret Modbus commands on his desktop. 1) Do I Need any special hardware to pass the data out of the PLC into the Router then into his browser. 2) As a trial can I send him MODBUS commands regarding my AND circuit? 3) How do I create such a command? 4) Is it possible for him to send me Modbus commands to change variables inside my program? 5) Are there web browser "plug-ins" for this idea? Thanks for reading and hopefully all of you can help me answer some of these questions.

Wanting to write to Balluff Smart Lights via IO Link Master IP #BNI EIP-502-105-Z015. I can find lots of literature on setting up the communication via E/IP in RSLogix 5000 but haven't located anything with Machine edition for writing the data over IP. I am utilizing an Rx3i platform with IC695CPU315 and IC695ETM001 for network access

Modbus comms between Schneider and allen Bradley
MbarrettAlpha posted a topic in Modicon / Telemecanique / Schneider Electric
Hi all, currently as part of a project I am trying to communicate between a Schneider M340 plc and an Allen Bradley micrologix processor. I am programming the M340 and the micrologix has been installed by another supplier. they have mapped the Modbus registers on their side and given me a spreadsheet with these. I am able to read values with no issue but I cannot write values back. i've included a screenshot or the read_var and write_var instructions I am using. I would really appreciate any help if anyone has any insight on this Mark -
I am trying to get the communication going between EZ3 EZAutomation Panel HMI and Omron NJ501-1300 PLC. I am currently using Modbus TCP/IP as a protocol. Has anybody figured out a way to do that? Or is there a better way to do this communication between HMI and PLC ? Right now I am using MTCP_Client_Connect function block to connect with HMI but it dont seem to be working. The IP address is correct along with Port no. I am still fuzzy about the Station address of NJ and the function code of the NJ for Modbus purposes. If anybody could help me out I would really appreciate it.

I'm attempting to connect a CJ1W-SCU32 modbus card with 2 ports to several modbus sensors. I am only reading from the senors, not sending any commands. I have been told two different ways to do this: 1. CMND block using Modbus RTU code 2804. 2. Using the Protocol Macro ModbusPM_Master with the PMCR function block. I've additionally found an easy modbus configuration tool that unfortunately seems to take up too many registers that I will be using. Does anyone have any examples of code for setting up MODBUS TCP with either of those 2 methods? I am having a hard time finding any. Thanks.

Hi Everyone, I am trying to connect a Toshiba TRSPUX10A plc to a hitech PWS6600 HMI (Beijer electronics). I am using RS485 connection, and trying to get the communication going between the plc and hmi using Modbus RTU protocol. The PLC is slave and and HMI is Master, and I have a Modbus slave tag table for the plc. HMI Software: ADP3 PLC Software: TRPGMS01 Our supplier of the product cannot assist me as he passed away, and the manufacturers of the systems refer me to each other but with no luck. I have asked numerous system integrators however they only work with the systems they supply. I want to read a Modbus slave tag: Holding register 4500001 in the plc and have it displayed on the hmi. Please advise if anyone could assist. Kind Regards Quintin

Hi everybody. I have 1 QJ71C24n-R4 with 2 channels CH1 & CH2 and I want to use Modbus RTU for both of channels to read data from electric meter. Now I can do it well with CH2 but cannot with CH1. The reason is echo back setting, my GX work 2 only able to prohibit echo back on CH2, not able on CH1. Does anyone know about this problem? Please give me some advise. Thank you so much.

Hello , I'm using DVP12SE11R Delta PLC . I would like to read data from an external device using RS485 communication. In the WPLSOFT i have informed that i gotta use MODRD command in order to read the data . but i am not sure how to use it properly. the data is formed as one bit ('1' or '0') i wanna read 10 registers using MODRD although those registers are not ordered one after another and i know MODRD can read 6 registers one after another. Then i would like to use that bit as a Normally Open contact in the WPLSOFT and turn on a coil. i would like to get some help with it. thanks.

[newbie] help regarding modbus communication

Hi Has anyone got any real life experience with the new Mitsubishi iQ-R series? I have been assigned a major capital project to replace our old ageing DCS system. Our current PLC backbone is about 40x Q2ASHCPU, 10x Q06UDEHCPU and about 2xA2SCPU all linked up via Melsecnet/10 network with communication links into the DCS system via Modbus RTU utilising the QJ71MB91 modbus card. Due to the nature of my companies process and the limitations on plant downtime it is estimated this project could take up to 5 years to complete, with this in mind I am wanting to install a system that will not be obsolete (or unsupported) in a few years, hence, I am very interested in the new iQ-R series with it being Mitsubishi's latest and greatest. However, recent communications with my local Mitsi rep is not filling me with confidence that the iQ-R series is not as well supported/developed as the Q series. A major requirement during the development stages of this project is the new ability of the new processors to be able to talk to the old DCS up until a point where the DCS nodes will be completed removed and replaced with a modern SCADA package. Hence, the requirement of a Modbus Slave card for the iQ-R (i.e. a QJ71MB91 equivalent) which I am told is in development, but has no fixed timescales. Previous experience with Mitsubishi developments of cards is normally years not months. Any information anyone can provide on their experience of the iQ-R series would be greatly appreciated and if anyone knows if a Modbus Slave card is in development that would be useful. I realise i could utilise the Q series extension rack with a iQ-R processor but this is not the route i want to go down. Thanks for any help and apologises for the war and peace. Cheers Matt

Hello, i have DOP-07s411 delta hmi and i want to interface it with microcontroller using modbus (RTU) protocol over RS485( 8 bit data,1 stop bit, parity none,19200 baud rate). i have good speed of communication if i do not use macros. But as i place background macro(background macro is only 4 lines ) it slow down and updates the display at every 3 seconds. i cant able to figure out what is the problem. I want to update display of HMI very fast.Please help me to troubleshoot the problem.

Hi, I'm trying to test the serial communications with my Micro820. I acquired a 2080-SERIALISOL so I could have "someone" to talk to. I want to use RS485, so I figured that I'd have to connect: Modbus pin 1 (D+) to serialisol pin A1 (+485) Modbus pin 2 (D-) to serialisol pin B4 (-485) Modbus pin 3 (GND) to serialisol pin A2 (GND) Now when it comes to CCW, the thing gets a little harder. I know I need to use the MSG_MODBUS block (in fact I need 2, one for the modbus and another one for the serialisol), and I guess I specify the interface I'm using on the TargetCfg field (data type MODBUSTARPARA). But how do I figure out that the Addr (UDINT) and Node (USINT) values are for my Modbus and Serialisol? Or am I doing it wrong? Does anybody know of any place where I can get some more guidance or even a funcional ladder program? Thank you in advance

Hi, I’m trying to control 10 Safety switchgear using AS interface, and since I’m using Beckhoff as a PLC I want to use "KL6211 | AS-Interface master terminal" as a Gateway but since this is the first time I’m using Beckhoff I’m a bit lost, So my questions are: - Is it a good idea to use a Beckhoff ASI terminal? - How to configure it? - Is there a possibility to configure it using embedded PC ( I’m using CX2030)? Excuse my English.

Hello guys, I am using Fatek PLC's to communicate with each other as a Master & Slave through zigbee which is connected through RS485. And I succeed. But the issue is that I have to communicate each other at a distance of about 2km where zigbee out of range to each other. I am bit confused here; 1) whether I use RF booster? Does it work? 2) Should I introduce extra PLC as a repeater between master slave? But this(extra added) PLC repeater also become as a master(Master Repeater).or any idea? Most important I can using Fatek Protocol or Modbus RTU or Modbus ASCII prootcol.

Hi! I have some concern dealing with the FX3U-485ADP-MB device which will be plan to install and a total of 17 modbus devices(Chinese brand converter 4-20mA to RS485) where going to communicate. I'm new to this feature of FX3U family and I'm using GxWorks2. Is there anyone that can guide me through this device/development? Is there a program block for this like the one I have been use for analog modules(FX3U-4AD)? Looking forward to your help! Thanks a lot! Marky

I am trying to export the Modbus points lists from a DAServer in Archestra SMC but I am getting an error message shown in the attached image. All options are greyed out and I cannot export the points list from the PLC node. I know there are points configured on the PLC node because data is updating the the InTouch application. Any help you can provide is greatly appreciated!
