I'm trying to read six input registers from a remote device but the software I put together doesn't seem to do much; no errors but no read-backs either. I'm a beginner, so the answer is probably simple. The remote device input registers start at 200 hex. The device uses TCP and the IP address is... -
I'm trying to read (PV process value) and write (SP set point) the temperature on a Omron E5CC temperature controller using LabVIEW, Modbus, RS-485. I'm new to Modbus and have installed the free LabVIEW modbus library. LabVIEW "Create Serial Slave" seems straight forward, but I'm having issues with...

I'm working on a Modbus Server (aka Slave) implementation for Serial communication. Has anyone experience with this? My immediate question is about the "RTU" format. Standard serial format uses CRLF characters to mark the end of messages, but RTU uses "3.5 characters of silence" on the serial...

This is a DSC module question: has anybody here experience with building standalone executables which include shared variables bound to DSC modbus i/o servers? I have an issue with deployment, possibly related to licensing. I posted on the dark side, but haven't got feedback yet. https://forums... -

LabVIEW 2016 Modbus Communication with a PLC Siemens SIMATIC ET 200SP Windows 7 Ultimate Hi, When I run my code it return error 66 at Read Holding Registers function. I ran this code as a VI on the development virtual machine and as a *.exe on real machine, but receive... -
I am working with a Universal Robot arm. I believe it is a UR-5. I was under the assumption that it could be controlled via Modbus, but I found that was incorrect. I need to use URScript commands. I am having a hard time getting started with this. I was wondering if anyone has written a VI that... -

I have been successful in communication with a Delta PLC using Modbus library support & even built some projects using this method of communication with more than one PLC. What I want to be able to do is to use the 'Modbus I/O Server' to set up the elements in my project & not have to use the Modbu...

Hi, I'm looking for a LabVIEW driver for IAI PCON-C motion controller. It can be controlled using serial or by MODBUS. (both using VISA) The protocol is complicated and a lot of digging is required, so I will appropriated if someone wrote this code and willing to share it. The exact controller mo...

Hi everybody! I'm trying to connect a JUMO oven controller to labview using a RS485 serial connection and Modbus RTU. I have the NI Modbus Library which has been very helpful except for a few things. Specifically, some of the addresses within the slave are very straight forward and are just a hex...

I've been scratching my head with this one and am hoping someone has dealt with it before. My physical setup is a PC, CAT5 cables, a couple of switches, an Eaton HMI, and an Eaton PLC. I'm talking Modbus TCP to the PLC using the library on NI's website. I'm using Wireshark to troubleshoot other pr...
