Hey,

I had a small problem with modbus connection that seemed to be all fine(Was connected and no errors in debug), but actually it didn't update values, but i had the error handling setting set to hide. 

Now here's my question if it's set to hide and there is some error does it drop the connection? Or will it still reconnect after the error just doesn't log the error?

I was looking at the diagnostics/debug and it didn't show me any timeouts but it looked like it only was asking 1 register for updates. after i disabled it and re-enabled it started to talk to me again(Started to poll/update all the registers). So right now i left the error handling to reconnect.(Only reason i left it in hide mode was so i could test registers that didn't respond for some reason, now i just turned off cyclical read on them) Modbus connection was "offline" for 2 days.

Also it would be awesome if we could disable/enable modbus driver from the visualization too,  I haven't found a way to do it. We can see the status of the driver that's it.

Regards,

Jürgen

Hello. Any ideas how can i read a UCHAR data type in configurator? I have a ventilation system with 0-Stop , 1- Economy, 2- Comfort, but i don't understand how to convert the value in configurator.

When is on, the value is 512, but i don't know from where that come. Thank you!

I'm looking for a description to understand in deep the difference between Reconnect and Resume.

Can you help ?

Hi,
I've this instrument EASTRON SDM630M

and i'm trying to read it in modbus.
Usually i start my test with modbus pull software.
I'm read the register number 4 - input register FC04 - (Voltage phase 3) in Floating32bit - BIGENDIAN

In comfortclick, to read the same value i need to set LITTLE-ENDIAN.

you can see that in BigEndian the value is incorrect.

Do you know why there is this different from Modbus Poll ?

Thanks in advice.

Hello everyone,

I am currently trying to connect and control a Daikin VRV central air conditioning system via the DTA116A51 board using the Modbus protocol. However, I am unable to read or write 3 or 8 bits... from the 16-bit Holding Register or Input Register to bOS. Do you have any solutions to this problem? Please help me.

I am currently experiencing an issue where the Modbus TCP connection does not automatically reconnect after being disconnected. The bOS still shows the status as "true", but I have to manually enable and disable it to get it to work again. This error occurred after I updated the bOS server to version 4.10.8. Is there any way to fix this?

We are writing to inquire about the following topics for our upcoming hotel building BMS project:

• What type of Comfortclick device is recommended for a hotel building BMS system?
• How many devices does Comfortclick support to connect with the Modbus TCP protocol?
• Can 2 devices be managed remotely on the same bOS interface account at the same time?

We appreciate your assistance.

I would like to address an issue regarding the Comfort Click Jigsaw 3 device and the PLC controller. Communication is carried out through the Modbus TCP protocol. The initial problem involves the mobile application displaying the online status of the Comfort Click device, but it lacks successful communication with the PLC controller. Changes in values within the application do not reflect corresponding alterations on the PLC controller. This issue has been temporarily resolved by halting the operation of the PLC and restarting it, but it reoccurs after some time.

The second problem occurred today in the form of the unavailability of the mobile application. When attempting to log in to the device, an error is displayed: "Error connecting to server." Additionally, on the Comfort Click web platform, I noticed that the status of my controller is marked as offline.

I kindly request your expertise in diagnosing and resolving these issues.

I am looking for a solution to connect bOS with PLC Logo!8 to control an intermediate memory area.
