1STEP 5V/204kHz
2.2 Example : Commissioning 1STEP 5V/204kHz
Configuring STEP 7 via HW Config
You begin by adapting the hardware configuration to your existing ET 200S station.
1. Open the relevant project in SIMATIC Manager.
2. Call the HWConfig configuration table in your project.
3. Select 1STEP from the hardware catalog. The number 6ES7 138-4DC00-0AB0 appears
in the info text. Drag the entry to the slot at which you have installed your
1STEP 5V/204kHz.
4. Double-click this number to open the DP Slave Properties dialog box.
5. On the Addresses tab, you will find the addresses of the slot to which you have dragged
the 1STEP 5V/204kHz. Make a note of these addresses for subsequent programming.
6. On the Parameters tab, you will find the default settings for the 1STEP 5V/204kHz.
Set the DI function as "external STOP". You must set the "external STOP, limit switch"
parameter as a normally open contact.
7. Save and compile your configuration, and download the configuration in STOP mode of
the CPU by choosing "PLC -> Download to Module".
Integrating the FC 101 Block into the User Program
Integrate block FC101 in your user program (for example, in OB1).
This block requires the DB1 data block with a length of 16 bytes. In the following example,
the start is triggered by setting the memory bit 30.0 with the programming device.
You may damage your system at the start of a run (4800 pulses forwards). It may therefore
be necessary to adjust the distance.
