Modbus profiles write_delay

[jmir]

Hi, I've seen that recently you have added a "write_delay" field.
Is it possible to use this modbus package on 20230607 firmware?

Thanks.

This feature has not been tested yet. But you can try at your own risk if you want.

Install through System config > System > Packages > Add package. Reboot LM after installation.

Hi I've tried but it seems that write doesn't work...

Anything in the Modbus logs or Error logs?

Hi I've tested and it works!
How are writes managed? I've seen that dependig on the value set in poll time, only one write is done at the end of each poll...

Thanks.

Writes can only happen between poll cycles. Polling cycle for a single device cannot be interrupted by a write operation.
You should adjust the poll interval so the bus is not completely occupied by reading.

Hi Daniel,

Are this packages in the latest firmware? 
We have done some tests and it seems that write_delay doesn't work unless we import them...

[Daniel]

What is latest firmware for you?
