CBus Logic Question

I was wondering if any one could provide me with a logic example for the following scenario:

I have two groups that control somfy blinds (One Group Up and Other Down). Both groups are a bell press for 3 seconds each. I would like to program them as one button on the PACA that can remember their last state and flip the commands.

 

Create a group address called say "Blind Toggle" and set it in your switch as a toggle function. Then you just need simple logic like

ONCE "Blind Toggle" = ON then PulseCBusLevel("Local Network", "Lighting", "Blind Up", 100%, 0s, "0:00:03", 0);
ONCE "Blind Toggle" = OFF then PulseCBusLevel("Local Network", "Lighting", "Blind Down", 100%, 0s, "0:00:03", 0);
