4.5 SM 113 sensor detection and address setting
The first time voltage is applied, SM 113 will check
all inputs to detect which sensors are connected.
If a valid signal is measured, SM 113 will detect that
a sensor is present and save the status.
If IO 113 indicates a sensor error or configuration
error, repeat the sensor detection. See section
8. Fault finding the product. Change DIP switch 6 on
IO 113 from OFF to ON, then switch from ON to OFF.
After approximately 5 seconds, SM 113 will reset and
the sensor detection is completed.
Example: (six pairs)

Fig. 7 Power on
Fig. 8 IO 113_1, DIP 6 "OFF"
Fig. 9 All indicator lights flashing
Power supply to SM 113 Description
Power on
The slave SM 113 detects sensor status
and communicates with IO 113 to set
the address.
Power off The slave SM 113 is off.

If more than one pair of IO 113 and SM 113
are used in a control system, make sure
the address setting is handled pair by pair.
Only one pair of IO 113 and SM 113 may
be on and initialised at a time when
performing settings. All other IO 113 and
SM 113 modules must be off; otherwise,
the address setting may fail.
