PNS Status and Control Data

4.1
The PAC8000 PROFINET Scanner provides 64 bits of input status data and receives 16 bits
of output control data. The application program in the IO-Controller system can monitor the
input status bits and can perform some control operations using the output control bits. This
data is associated with slot 0 submodule 1 in the configuration.
4.1.1

Output Control Register

The PNS's 16 bits of output control data can be used to trigger module actions.

Description
0 to 1 transition resets the PNS.
1 to 0 transition has no effect.
0 to 1 transition sets the PNS to failsafe state.
1 to 0 transition has no effect.
0 to 1 transition commands the PNS to clear failsafe state
1 to 0 transition has no effect.
1 = Enable Heartbeat feature.
0 = Disable Heartbeat feature.
Remote application (host) should toggle this bit to indicate it is
alive. When there is no update to this bit for more than
configured communication timeout, the PNS treats it as a
communication/application failure and goes to failsafe state.
Applicable only when "Heartbeat Enable" in output control
register is '1'.
