Memory requirement of the counter relay
The comparator function block requires 32 bytes of memory
plus 4 bytes per constant on the function block inputs.
Text output function block
The EZD device provides 32 function blocks that operate in an
EZ800 as text output function blocks. These function blocks
work in the EZD device as contacts and coils in the same way
as in an EZ800. In the EZD device, texts, actual value output
and setpoint entry are implemented using the appropriate
visualization elements.

The text function block was adopted from the EZ800 so that
the circuit diagram is compatible. This simplifies the
processing of EZ800 programs. EZ800 programs with text
function blocks can be loaded directly onto the EZD, either
from the memory card or from EZSoft. The contacts and
coils are processed in the same way as in an EZ800.
However, texts are not output.
The function block requires the entire memory, even if no
texts have been transferred.
J
Do not use the text function block on the EZD device. This
will use up memory unnecessarily with unused functions!
