To change the value of parameter 65000 with the variable table perform the following
steps:
1) Enable monitoring by clicking the Monitor variable button.
2) Write 02hex to address DB1.DBB 1 by entering B#16#02 in the modify value
column.
3) Write the new preset value in hexadecimal to address DB1.DBD 12 by entering
the value in the modify value column. (Ex.DW#16#000001F4)
4) Click the Modify variable button. The status value of DB1.DBB 12 should now
contain the new value.
5) Run the program-right click on M8.4 and click “Modify address to 1” to run the
program. Then stop the program by right click and click “Modify address to 0”.
6) The status value of DB2.DBD 6 should now have been changed to the new
preset value.
7) Change the value in DB1.DBB 1 to 01hex (B#16#01#) and click modify variable.
8) To set the encoder to the new preset value bit 12 in control word must be set to
1. This is done by writing 1000hex (W#16#1000) to address PQW 2. Then click
the button Modify variable to make the preset of the encoder.
9) The encoder can now at any time be set to the preset value by setting bit 12 in
control word (G1_STW).
