Example 2:
Copying of marker blocks, definition of a range with offset
The content of marker bytes MB15 to MB18 is to be copied to marker bytes
MB65 to MB68.
• Parameters of function block BT01:
After a rising edge from 0 to 1 at coil BT01T_ the content of MB15 to MB18
is copied to the marker bytes MB65 to MB68.
Example 3:
Copying of marker blocks, definition of a range in a different format
Marker range MD60 to MD62 is to be copied to MW40 to MW45.
• Parameters of function block BT01:
• Source range: I1 MB15
• Target range: I2 64
• Number of bytes: NO 4
• Marker MB01: 1
→
Destination range: Constant 64:
Marker MB01 plus offset: 1 + 64 = 65 MB65
