Applies To:
  • CitectSCADA 5.xx

Summary:
Each station on the LIL link can contribute up to 256 parameters to the LIL "Global Database". Typical information such as setpoints, auto/manual mode, external/internal control, and computer/local etc. are supplied by each station (as a status word or a parameter) on the LIL link. Each bit in the status word represent a state of each station on the LIL link.

The current MooreP driver (ie V2.04.000 or earlier releases) can only read the status parameters from the Global Database but could not write to the individually bits within each status word.

 

Solution:
CIT has confirmed this to be a driver problem in Citect for Windows versions V5.x. This problem has been fixed in MooreP driver version V2.04.01.00 and above.

You can now write to individual bits in the "Global Database" using address formats Cx.z or CxPy.z where:

x = channel number

y = parameter number

z = bit number 0..15.
