5 Function blocks
5.4 BT, Data block Transformer
Control Relay easy800 11/11 MN04902001Z-EN www.eaton.com 155
CPY mode, copy marker ranges
There is one source range and one destination range. The source range is
specified at >I1. The destination range is specified at >I2. The length of the
destination range is specified by the number of bytes at the >NO input.
The content of the source range is copied to the marker bytes in the
destination range.
The function block executes the copy operation if there is a rising edge from
1 to 1 at the BT..T_ (Trigger) coil.
The error outputs E1, E2 and E3 are evaluated regardless of the status of the
trigger.
Example 1:
Copy of marker blocks, direct definition of marker ranges
The value of marker byte 10 to 14 is to be transferred to marker bytes 20 to
24.
• Parameters of function block BT01:
After a rising edge from 0 to 1 at coil BT01T_ the content of MB10 to MB14
is copied to the marker bytes MB20 to MB24.
• Source range: I1 MB10
• Target range: I2 MB20
• Number of bytes: NO 5
