When CCF loops with output FCMs configured for warmstart are placed in the
MANUAL mode by either a warmstart or operator action, their tags are shown
with a white background. When device loops configured for warmstart have their
DEV_CMND parameter set to NO COMMAND by either a warmstart action or
TCL command, their tags are also shown with a white background. Note that the
loop warmstarted for a given channel is the loop whose tag is shown in the TRIO
Block Display. If two or more loops reference the same channel, only the last
loop downloaded participates in warmstart and is listed on the TRIO Block
Display.

Normally, writing an output causes the value to show red until the
value is actually updated. However, writing a forced I/O point in
