Forming the signal status for blocks
This block provides the standard "Form and output signal status for technological blocks"
function that is described in the APL Online Help.
The worst signal status
ST_Worst
for the block is formed from the process values (4 to 20 mA
and HART variables):
●
PV_In.ST
●
PV.ST
●
SV.ST
●
TV.ST
●
QV.ST
Release for maintenance
This block provides the standard "Maintenance enable" function that is described in the APL
Online Help.
