2.2 Example : Commissioning 1STEP 5V/204kHz
ET 200S Positioning
20 Operating Instructions, 05/2007, A5E00124871-04
Testing the Configuration
Start an incremental run and monitor the associated feedback.
1. Using "Monitor/Modify Variables", check the residual distance and the status bits POS
(positioning in operation) and STS_DRV_EN (pulse enable).
2. Select the "Block" folder in your project. Choose the "Insert > S7 Block > Variable Table"
menu command to insert the VAT 1 variable table, and then confirm with OK.
3. Open the VAT 1 variable table, and enter the following variables in the "Address" column:
– DB1.DBD8 (residual distance)
– DB1.DBX13.7 (POS, positioning in operation)
– DB1.DBX13.0 (STS_DRV_EN, pulse enable)
– M30.0 Start by means of the programming device
4. Choose "PLC > File Connect To > Configured CPU" to switch to online.
5. Choose "Variable > Monitor" to switch to monitoring.
6. Switch the CPU to RUN mode.
Result
When you switch the CPU to RUN, the following results are obtained:
● The RDY LED lights up.
● The POS status bit is deleted.
● The STS_DRV_EN status bit is set.
Start the run by setting memory bit 30.0 ("Variable > Modify >").
The following result is obtained during the run:
● The POS status bit is set (you can see this by monitoring the variable); that is, the POS
LED lights up.
● The residual distance is continuously updated.
● The STS_DRV_EN status bit (pulse enable) is set.
The following result is obtained after the run has been completed:
● The POS status bit is deleted (you can see this by monitoring the variable); that is, the
POS LED is no longer illuminated.
● The residual distance is 0.
● The STS_DRV_EN status bit (pulse enable) is set.
