Thanks for the quick follow up!
I just tried the following with a single output:
This was unsuccessful, so next I tried:
This was also unsuccessful, so next I tried:
This was also unsuccessful, so next I tried:
This was also unsuccessful, so next I tried:
Still no success to report.
Did I attempt the settings you had in mind correctly? I also tried putting 0x00FF in the start byte box but it didn’t accept this input and changed it to 0 when I closed the window. Is there something else I should try?
Best regards,

Hello,
This post is in regards to a modbus communication issue I am working through in DASYlab 2022.1.
I am having difficulty getting DASYlab to communicate via modbus with an automation direct Stride SIO-MB16CDD2 which I am using to control some pneumatic valves. The Stride I/O module specifications for network connectivity are as follows:
The Stride I/O module appears to be working correctly, as I can communicate with it by putting the devices IP address into a web browser, and using the web interface to turn on digital outputs has the desired effect.
The network settings on my Stride I/O module are as shown (these are default settings):
The full manual for this device can be found here: https://cdn.automationdirect.com/static/manuals/stridefio/siomb16cdd2ug.pdf
Here is a screenshot of the portion of the manual that appears to be relevant to the issue I’m dealing with:
My DASYlab control process is currently very simple as I’m currently just trying to successfully establish control of digital outputs:
The switch settings are as shown below:
The modbus digital output settings are currently as shown below:
It would be greatly appreciated if someone with knowledge in this area could help me understand what I need to do differently to avoid getting the following error:
In addition to the settings tried here, I have tried a bunch of different combinations of addresses and start- register values in the DASYlab modbus digital output but none have worked. The values shown above are the ones that I thought had the highest likelihood of working. Networking, Hex, and communication protocols are not my area of expertise and I really don’t understand much about coils and registers so feel free to point out any essential steps that I didn’t mention that may seem obvious.
Thanks for any help you can provide!

Adding content for posterity
Great news! – It started working once I set the start-register to 488 as you suggested.
I’m including screenshots in this reply of all the settings I used to get it working:
Note that in the image above showing the IP address there is a 02 after the 5 that isn't shown due to the text box being too small. I had entered the 192.168.1.100 portion and DASYlab automatically adds a :502 to the end.
The computer ethernet card was set to a static IPv4 address of 192.168.1.101 and the computer was connected to the Stride IO module with a standard "straight thru" RJ45 ethernet cable.
I was also able to get the digital inputs working using the following settings:
Hopefully this will help others.
Thank you for your assistance with this issue JRys.
