Description
PV 14.0 REAL 0.0 The effective process value is output at the "Process value" output.
The valid values depend on the sensors used.
LMN 18.0 REAL 0.0 The effective "Manipulated value" is output in floating point format at the
"Manipulated value" output.
LMN_PER 22.0 INT 0 The manipulated value in I/O format is interconnected with the controller
on the output "Manipulated value I/O".
QPULSE
24.0
BOOL
FALSE
The manipulated value is pulse-width-modulated at the QPULSE output.
QLMN_HLM 24.1 BOOL FALSE The manipulated value is always restricted to a high limit and low limit.
The output QLMN_HLM signals that the high limit has been reached.
QLMN_LLM 24.2 BOOL FALSE The manipulated value is always restricted to a high limit and low limit.
The output QLMN_LLM signals that the low limit has been reached.
QC_ACT 24.3 BOOL TRUE This parameter indicates whether continuous control component will be
processed the next time the block is called (relevant only when SELECT
has the value 0 or 1).
