5.2 Control and status bytes
Channel 1
Process data mode
Control byte 1 (for process data mode)
Control byte 1 (CB1) is located in the output image [

Bit Name Description
CB1.7 RegAccess 0
bin
Register communication off (process data mode)
CB1.6 Reset 1
bin
all errors that may have occurred are reset by setting this bit (rising edge)
CB1.5 Enable 1
bin
Enables channel 1
CB1.4 GetLatchData 0
bin
Show the current position in the input process data
1
bin
Show the current latch value in the input process data
CB1.3 enLatch
FallEdge 1
bin
External latch event is enabled (for latch inputs with falling edge, the
terminal saves the current position)
CB1.2 enLatch
RiseEdge 1
bin
External latch event is enabled (for latch inputs with rising edge, the
terminal saves the current position)
ATTENTION: Higher priority than CB1.3 !
CB1.1 SetPos 1
bin
Position value is set with register R1 [ } 41] (rising edge)
CB1.0 enDithering 1
bin
Dithering is active (when R32.5 [
}
43] =1)
Status byte 1 (for process data mode)
The status byte 1 (SB1) is located in the input image [
}
