Post by jp23 on Unable to Connect to Modbus RTU Device ^{CODESYS Forge talk (Post)}
Hi all, I am attempting to use the Control Win V3 soft PLC to control a WAGO 750-315 remote I/O system via modbus RTU communication. I am struggling to connect to the device. I have been following this tutorial: https://www.youtube.com/watch?v=YlRfkESaNds I have setup my devices as shown in the images below. I have verified that my com port settings are correct as I am able to connect/control using modbus simulator software with these settings. I have also connected to a modbus master simulator program as instructed in the video, but the orange triangles will not go away. Additionally, I have updated my settings to 485 using the PLC shell. I have also set "always update variables" to enabled (1). Serial port, PCI-Bus, and modbus serial device status all show as "Not Running."

Post by niallel on CamBuilder and first boundary position not zero ^{CODESYS Forge talk (Post)}
Hi, I've read the CamBuilder documentation and it shows to use the left boundary of the first segment as SMCB.BoundImplicit(), so that the transition is as smooth as possible. With this it sets X and Y to 0. My first slave position is not 0 (say for example it's 100), so I would set it with SMCB.Bound(0,100). My question is that when the cam goes back to the start (Periodic := TRUE) , will it blend with the last position (360, 100) if I do this? I imagine it will, but the documentation isn't clear as the information in the Periodic Cams only says to set Smooth Transition in the cam properties - but when I'm defining it with code there isn't an option for Smooth Transition to be set. Hope this makes sense? Many thanks,

Post by ranadheer on Assistance for MQTT configure with external broker (Mosquitto) ^{CODESYS Forge talk (Post)}
Hi everyone Am trying to make establish MQTT connection , where am using IIOT example for this as a demo mode. where i had given IP-address of of local Linux application as a 172.31.239.67 and port number as 1883 in the PLC_PRG itself, and preparing the publish message by manually as " this is from published message", and this should receive at the subscriber side. Aim: To make communicate external publisher to the CODESYS by using MQTT protocol. By any chance having reference documents about this implementation please share here. and suggest the process to make it possible. I had uploaded reference project file after updating address in th PLG_PRG, kindly assist to configure with the broker

Post by ben1 on Help understanding analog in-/outputs ^{CODESYS Forge talk (Post)}
Hi there mate Most PLC's have a very similar concept with AI/AO - have you used any other software before? I have not used a Wago before myself, but I assume the concept would very much be: 1. Add the analog in & out cards to your hardware config. 2. Setup the raw input scaling on the hardware (eg. 4 - 20mA = 4000 - 20000) 3. Use a built in or homemade scaling block to scale your input as needed (eg. 4000 - 20000 = -100 - 2000kPa. 4. Write code as required 5. Scale output as needed (eg. 0 - 100% = 0-10000 = 0 - 10V) Is this the information you require?
