Not in use.
10.11.2.2. SW3
The two bits of the DIP-Switch "SW3" are used for the commissioning mode (COMNG_MODE).
●The setting of the DIP switch SW3 is read during power-up. It is not permitted to change the settings
during normal operation as this may cause an error.
●The hardware configuration must include the correct 'Safe digital I/O' module. If the DIP switch is set
for SM (Safety mode) then use the 'Safe digital I/O (SM)' module. Alternatively if the DIP switch is set
for CM (Commissioning mode) then use the 'Safe digital I/O (CM)' module. Both modules are resident
in the Step7 or PCWorx hardware catalogue after the device GSDML (Step7/TIA) or FDCML (PCWorx)
file has been imported into it.
●"COMNG_MODE" occupies 1 byte for input data and 1 byte for output data.
●Diagnostics messages are supported.
●Parameters for safe-IOs are fixed in the firmware and are not adjustable
●F-Address should be in a parameter
Caution
In a production environment the SI unit must only be used in SM (Safety Mode)
