Self tuning PID loop.

Example of ADAPTS
2000 C ADAPTS CONTROL LOOP STATISTICS (LOGICAL

2002 C FIRMWARE) STATIC PRESSURE CONTROL

2004 C DIRECT CONTROL LOOP

2006 C INPUT = %X%SSP

2008 C Output = %X%LP1

2010 C SETPOINT = %X%SSS

2012 C SAMPLE TIME = 1 SECOND

2014 C GAIN = %X%KC

2016 C TIME CONSTANT = %X%TC

2018 C REVERSE ACTING FLAG = 1

2020 C LOW LIMIT OF INPUT = -0.1

2022 C HIGH LIMIT OF INPUT = 5.0

2024 C LOW LIMIT OF OUTPUT = 0.0

2026 C HIGH LIMIT OF OUTPUT = 100.0

2028 C ERROR DEADBAND = %X%DB1

2030 C NOISY PROCESS VARIABLE = %X%NP1

2034 C ERROR REPORT POINT = %X%ERR

2036 IF (%X%RP1.LT.%X%LP1) THEN GOTO 2042

2038 ADAPTS (%X%SSP, %X%LP1, %X%SSS, 1, %X%KC, %X%TC, 1, -0.1, 5.0, 0.0, 100.0, %X%DB1, %X%NP1, %X%ERR)

2040 C SUPPLY FAN RAMP

2042 TABLE ($SPFRMP %X%RP1, 0, 0, 180, 100)

2044 C SUPPLY FAN VFD SIGNAL

2046 MIN (%X%SVO, %X%LP1, %X%LP1)

SIEMENS "adapt" statement (PPCL)

I'm quite familiar with how to write a LOOP statement but have had very little exposure to the newer "ADAPT" statement. Does anyone have anything in writing, perhaps a section out of a training manual that can display to me exactly how this command line works and how to write it? Has a new section been added to the PPCL manual to include this statement? If so, can someone e-mail me the section?

Also, how does this statement differ from a LOOP statement?

Thanks in advance.
