8 Guidelines for station planning
8.1
Module arrangement
8.1.1
Random module arrangement
The arrangement of the I/O-modules within a BL20 station can basically be chosen at will.
Nevertheless, it can be useful with some applications to group certain modules together.
8.1.2
Complete planning
The planning of a BL20 station should be thorough to avoid faults and increase operating reliability
If there are more than two empty slots next to one another, the communication is interrupted to all
following BL20 modules.
NOTE
A mixed usage of gateways of the BL20 ECO and the BL20 standard product line and I/O
modules of both product lines (base modules with tension clamp terminals) is possible
without any problems.

I/O modules
NOTE
Next to the gateway, only base modules with tension clamp terminals and ECO-modules
can be used.
Base modules with screw terminals can only be used, if a power supply module (BR or PF)
with screw terminals was set before.
