Contacts
BT01E1 to BT32E1: the number of marker bytes exceeds the
source or destination range.
BT01E2 to BT32E2: source and destination range overlap.
Only valid for CPY mode, copy marker ranges.
BT01E3 to BT32E3: the specified offset is invalid.
Coils
BT01T_ to BT32T_: trigger coil of the transfer data block
function block.
Memory requirement of the transfer data block
function block
The transfer data block function block requires 48 bytes of
memory plus 4 bytes per constant at the function block
inputs.
Function of the transfer data block function block
The transfer data block comparator function block has two
operating modes.
Initalising INI marker ranges
There is one source range and one destination range. The
source range is specified at
>I1. The length of the source
range is one byte. 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 transferred to the marker
bytes in the destination range.
The function block executes the transfer if there is a rising
edge from 0 to 1 at the BT..T_ (Trigger) coil.
The error outputs E1, E2 and E3 are evaluated regardless of
the status of the trigger.
h
No data blocks are initialised if an error occurs.
