Re: Modbus Error Variable
Thank you Amar, I think that's ok, it works for what I want.

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.
Is this possible?
How can I configure the extended data?

Send Write Single Register by c code in Modbus
Hi there,
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.
Is it possible? How can I do this?
