6.5.2 Assignments for PROFIBUS DP and PROFINET IO-relevant
Interfaces for the Processing Unit
Control byte
Bit No. Corresponds to Signal
0 DISA
1 SEL0
2 SEL1
3 SEL2
4 SEL3
5 TRN
6 TRG
7 RES
Note
The SEL0, SEL1, SEL2, SEL3, TRN and RES signals only take effect when
DISA=1.
Status byte
Bit No. Corresponds to Signal
0 IN_OP
1 TRD
2 RDY
3 READ
4 MATCH
5 N_OK
6 -
7 -
Note
Writing the control byte and reading and evaluating the status byte must be
analogous to the time diagrams in Selecting Modes.
6-12
Function
Disable: Disable manual control panel input, code selection and train,
error acknowledgment, start of the processing unit
Select 0: Code selection bit 0
Select 1: Code selection bit 1 (if TRN=0) / train code (if TRN=1)
Select 2: Code selection bit 2
Select 3: Code selection bit 3
Train: Train new code
Trigger : An evaluation is started on the positive-going edge
Reset: Reset error
Function
In operation:
•
0 = error message is displayed.
•
1 = SIMATIC VS 130-2 functional, no errors
Trained:
•
In Run:
0 = selected code has not been trained
1 = selected code has been trained
•
In Training (TRN=1)
0 = training active
1 = acknowledgment signal (RDY=0)
Ready:
•
0 = device startup or SIMATIC VS 130-2 in Stop
•
1 = SIMATIC VS 130-2C in Run
Evaluation result: Code was localized and decoded
Evaluation result: Code matches learned code
Code was not legible.
