1 About These Instructions
These operating instructions describe the structure, functions and the use of the product and will
help you to operate the product as intended. Read these instructions carefully before using the
product. This is to avoid possible damage to persons, property or the device.
Retain the instructions for future use during the service life of the product. If the product is passed
on, pass on these instructions as well.
1.1 Documentation concept
This manual contains all information about the bus-independent I/O-modules for the modular
Turck IP20 I/O system BL20.
The following chapters contain a short BL20 system description, exact descriptions of the I/O-mod-
ules’ functionality and their Technical data as well as all general information concerning the whole
system as for example mounting/dismounting, labeling etc. In addition to that, the manual contains
a short description of the BL20 DTM in PACTware.
The bus-specific BL20-gateways, the connection to the different automation devices, the maximum
system extension as well as all other bus specific information are described in separate manuals
(www.turck.de).
