6.2.2 Control Loop Data
Control loop data occupies five LIL channels. The starting channel is entered during configuration of the ODC
operator display function block for each loop, as LIL CHAN (n). The first channel for each loop can be viewed in
station data starting at channel 5/parameter 2 for control loops and channel 6/parameter 2 for a sequencer loops.
The station configuration entry (both local and graphical PC-based) will indicate the next available open space of
five contiguous channels. Another starting channel can be entered but it is important to utilize the lowest total
number of channels.
Channel locations n through n+4, in the table below, identify variables that will be available on the LIL for each
control loop. All parameter 1 data (e.g. P-process) is global and is transmitted every 0.5 second. All other data is
sent out on command.
