Supplement to A.2.2 and A.2.3 (data byte DL n +11):
1 = asymetrical controlled system (only with
twoĆstep controllers, otherwise 0)
0 = symmetrical controlled system
Byte for selfĆtuning parameters
7 0Bit 6 5 4 3 2 1
SelfĆtuning controller
1 = selfĆtuning once
0 = selfĆtuning with repetition
only used by the
FB 162 for 32
messages
0 1 = Start of the selfĆtuning function
0/1 0/1
0 0/1 0 0 1 0
1 0 = Stop of the selfĆtuning function
Note:
The FB supports reading of bytes DRn + 11 (heating and cooling parameters calculated) and
DLn + 15 (minimum jump) in messages 0 to 12 only if main control byte 1, bit 2 = 1.
(Reason: LE is only possible if main control byte 1, bit 2 = 1.)
You may only evaluate the bytes if you have previously read them.
