Complete basic frame $P_ACTBFRAME

The chained complete basic frame is determined by the variable. The variable is readonly.

$P_ACTBFRAME

corresponds to

$P_NCBFRAME[0] : ... : $P_NCBFRAME[n] : $P_CHBFRAME[0] : ... : $P_CHBFRAME[n].

Programmability of the complete basic frame

System variables $P_CHBFRMASK and $P_NCBFRMASK can be used to select, which

basic frames to include in the calculation of the "complete" basic frame. The variables can

only be programmed in the program and read via the operator panel interface. The value of

the variables is interpreted as a bit mask and specifies, which basic frame array element of

$P_ACTBFRAME is included in the calculation. $P_CHBFRMASK can be used to define,

which channelspecific basic frames are included, and $P_NCBFRMASK can be used to

define, which NCU global basic frames are included in the calculation. When the variables

are programmed, the complete basic frame and the complete frame are calculated again.

After RESET and in the default setting, the value of $P_CHBFRMASK equals

$MC_CHBFRAME_RESET_MASK and the value of $P_NCBFRMASK equals

$MN_NCBFRAME_RESET_MASK.

$P_NCBFRMASK = 'H81'

$P_CHBFRMASK = 'H11'
