Output as signal level warning (VMA)
NOTE
This function can be configured only via IO-Link!
You can configure the Q1 or Q2 output that a signal is given out when the
received light level gets to low. The level threshold can be adjusted within
the range of 0 … 65,535. If the signal exceeds or falls below the configured
level, the output changes its status. Hysteresis cannot be configured. The
output behavior can be inverted.
Depending on the application, the setting must always be defined by the
user. When using the signal level warning (VMA) we always recommend to
perform a reference measurement onto an object with known and constant
optical properties.
