3.9 Configuring the analog expansion unit

Processing analog input/output values
You access the now configured analog input/output values via marker words
(MW). The process image is provided in the marker words.
Marker configuration with operation on 800 standard
(from device version 02)
Table 9: Marker configuration using analog input/output values
￫
The parameters configured here are stored retentively and only
in the expansion unit, not in the easy800 standard.
This means: You must complete this configuration again when
exchanging a configurable expansion unit.

￫
A new analog expansion unit is factory set for all inputs/outputs
to be activated. All the assigned marker words are thus also
taken.
For your expansion unit only configure the analog inputs/outputs
that are actually required.
This has several advantages:
• More free marker words for use in the program or in the
visualization.
• Only relevant error messages, as otherwise an activated but
unconnected input will signal a fault such as a wire
breakage.
• Shorter reaction times due to the faster data exchange
between easy800 standard and expansion unit.
