Switching input/output
The BPS is equipped with two, freely programmable, optically decoupled switching inputs/outputs, SWIO1
and SWIO2.
• The switching inputs can be used to activate various internal functions of the BPS (e.g., Measure
-
ment Stop/Start, Teach Preset, Reset Preset).
• The switching outputs can be used to signal the state of the BPS and to implement external functions
independent of the superior control (e.g. position value/velocity value invalid, position and velocity
limit value exceeded, device error).
• The control can use switching inputs/outputs as digital I/Os.
If no internal BPS function is connected to the switching inputs/outputs, the ports can be addressed
as two inputs, two outputs or as one input and one output of a digital I/O component.

The function as an input or output is set via PROFINET parameters (see chapter 8.6) or using
the webConfig configuration tool (CONFIGURATION > DEVICE> Switching inputs/outputssee
chapter 9.3.1).
If SWIO1 or SWIO2 is to be used as digital input or output, the configuration must be performed
in module 4 (see chapter 8.6.6) or module 5 (see chapter 8.6.7).
NOTICE
Maximum input current
The maximum input current must not exceed 8 mA.
