DIO Driver Issue Codesys

nathant · Post by **nathant** » 05 Dec 2023, 03:19

Hello - I am trying to configure the DIO modules for a RevPi Connect SE in Codesys but I keep getting the error that the piBridge can't find the Extension Gateway, Extension Modules, or Extension Bus. I have tried various versions of the RevPi packages with various versions of Codesys. So far nothing has worked. Please let me know how I can solve this.

Please don't delete this post. I need an answer to this to make my $500 product function as intended. Thanks.

Dear nathant, installing CODESYS with the Revolution Pi can be challenging. There are paths that can lead to dead ends. To help you navigate through the installation jungle, I can provide you with this checklist which will lead you to success:
https://kunbus-gmbh.atlassian.net/servi ... 2687893508
Then simply run the "Example Blinking Light" demo which is available here:
https://revolutionpi.com/tutorials/beis ... -light-2-2
You don't have to program this separately, it is available as a ready-to-use application in the download area under Revolution Pi Library for CODESYS V1.4.0.0 (ID: 6985)

So that first link is saying that I need 32bit Codesys? I really hope this is the solution because as I said I downloaded the RevPi package numerous times.

So I have downloaded the 32 bit version of Codesys 3.5.19.0 and still get the same issue. What's going on. I need a solution as soon as possible. It really shouldn't be this difficult. Please allow me to set up a Teams meeting or something. I need your $1000 worth of product to work as I intended.

Dear nathant, please check whether you have also installed a 32-bit Revolution Pi image, for example with

Code: Select all

pi@RevPi99988:~ $ cat /etc/revpi/image-release
2023-09-26-revpi-bullseye-armhf.img
pi@RevPi99988:~ $ uname -a
Linux RevPi99988 5.10.152-rt75-v7l #1 SMP PREEMPT_RT Tue, 26 Sep 2023 09:43:32 +0200 armv7l GNU/Linux

Great. I added the random file in the Linux terminal like the instructions said. That removed the error with the piBridge. Unfortunately a few minutes later, now I can't even ping the device. What's going on now? I mean this is pathetic man. Every step of the way presents a new challenge that will take multiple days to solve.

Will installing a new image reset the IP address I set for Ethernet Port 1? Because that's not an option for me since the microHDMI port has broken and fallen into the module. I will not be able to reset the IP address via ethernet either because my company won't supply me a DHCP capable router.

I apologize but I really don't understand what any of the code you pasted is for. Am I supposed to follow this tutorial https://revolutionpi.com/tutorials/imag ... nd-stretch ?

Nathan, I feel really sorry for you - with a broken HDMI port, Ethernet without DHCP and all these other difficulties with CODESYS. I can only say I'm with you so that you, and we, can get off to a successful start together in the Revolution Pi community!

Reset to factory defaults → see RevPi Checklist

Download and flash a compatible 32 Bit image, i.e. RevPi Bullseye (09/2023) (ID: 7478) - see Video Tutorial #1 Image or if you enjoy reading yes, the link above you have already found
You should use a DHCP capable network device. Even a Software DHCP Server is possible, i.e. that one https://www.dhcpserver.de/cms/download/ and perform the first login
Then after first login perform the "revpi-factory-reset" so you reset to factory defaults "marriage" between front and credentials and your device. If you have a RevPi Connect 4 device, you see a terminal window and just click ok and reboot

Install CODESYS → see CODESYS Checklist

Latest issues is that I can connect to the IO module fine in Codesus. But when I map an output variable (in the RevPi DIO in Codesys), the correct pin doesn't change with the value. For instance I mapped Output 13 to my test variable but when I toggled it on, the signal shows up on Outputs 3 & 5 (it's different and random on every download), not 13. Do you know what this issue is? Thanks.
