We did a site about 6 months ago that had a PACA and a B'n'W T screen. We attempted to use the GetUnitParameter statement to poll the light level from a sensor. But the PACA was not capable of doing this, yet we have successfully done this on many occasions with the colour and Schedule Plus. I am in the process of designing a similar site, does anyone know if we can now use the GetUnitParameter statement in a PACA?
