Setting of the actual value can be triggered via a 0/1 signal edge at in-
put terminal 1 during processing of a block.
The dimension system is then re–synchronized. The following blocks
are then executed in the new reference system.
Block 13
v
1
0
S
Brakes along the braking ramp
S
Block change with delete distance to go
S
The actual value is set to the position in P85:28 (signal
position)
––> the new reference system applies from this position
S
Traverses as programmed in the block
What should be done?
The following has to be done in order to use the "flying actual value
setting" function?
1. Connect the signal transmitter to digital input 1 (X5 terminal I/Q1)
––> the signal transmitter must be high active
––> refer to Chapter 2.3 and 2.4
2. Assign digital input 1 to the "flying measurement/actual value setting"
function
––> in the SimoCom A under the tab "Par" and entry "Digital inputs/
outputs"
––> by setting SIMATIC S7 P31 to 27
3. Program the traversing block, activating the "flying actual value
setting" function
––> set PSW.10 to "1"
4. Enter the value for "actual value setting"
––> P85:28 (signaled position) = required actual value
