Modbus Polling On connect estalished

Hi there,

I am configuring a Modbus with several polling groups to read at different intervals, my problem is that I have a customer requirement that needs to read all groups when the connection is established.

How can I configure the extended data?

I need to send a Write_Single_Register in a modbus master only once.
I have a custom console application written with c language and I am not being able to find out how can I achieve this.
