21.2 KS8x (KS 800/ KS 816 controller function - no. 59)
Each
KS8x function handles a controller of KS 800 or KS 816.
T he
analog and digital inputs can be used to send the control signals to the controller in KS800/16. The analog outputs
provide the process and controller values.
Inputs and outputs
Analog inputs
C x
Connection to one of the
C1...C16
outputs of node function
C_KS8x
W
Controller set-point
Yman
Correcting variable in manual mode
Digital inputs
a/m
0 = controller is in automatic mode 1 = controller is in manual mode
C off
0 = controller is switched on 1 = controller is switched off
w/w2
0 = controller is in automatic mode 1 = 2nd set-point is active (safety set-point)
we/wi
0 = external set-point is active 1 = internal set-point is active
ostart
0 = don’t start self-tuning 1 = start self-tuning
Digital outputs
et-err
0 = no engineering error
1 = engineering error
(several KS8x controller functions on a controller channel)
valid
0 = no data 1 = data were received
xfail
0 = no sensor fail 1 = sensor fail
Analog outputs
X
Controller process value
Y
Controller correcting variable
