8.7 Interface to the ETC
8.7.1 Data blocks
The integrated PLC has an internal RAM range available which is divided into
16 so−called data blocks. Each data block (DB) contains 256 data words (DW)
of 16 Bit.
8.7.2 System variables of the ETCxC
The system variables represent a predefined number of variables from the
data blocks.
In CoDeSys the system variables can be inserted into a project via the menu
item Insert
W operand W System variables or the input assistance (via
function key "F2").
the following is a list of the defined system variables:
