Hi all,
I'm really struggling here and any pointer in the right direction would be appreciated. I have checked all the App Notes and I have tried nearly all the suggestions and I'm not getting very far. I'm able to set output bits 1 & 2 but cann't clear them. It looks like I have some sort of communications to the DMC-30011 but I don't know how to program the DMC to send or reply. Let's start with a simple question: do I need to have a continuously running program on the DMC sending info to the master or does the DMC only respond when there is a request from the master?

Matt,
Thanks for your helpful suggestions. But my real problem is fundamentally a lack of understanding of the relationship between modbus addressing on the HMI and the associated array space on the DMC-300xx. I don't know how to configure this.
