The application program in the IO-Controller system can monitor theinput status bits and can perform some control operations using the output control bits. Thisdata is associated with slot 0 submodule 1 in the configuration.4.1.1 Output Control RegisterThe PNS’s 16 bits of output control data can be used to trigger module actions.OutputBitsName Description1 (LSB) Reset 0 to 1 transition resets the PNS.1 to 0 transition has no effect.2 Set Failsafe 0 to 1 transition sets the PNS to failsafe state.1 to 0 transition has no effect.3 Clear Failsafe 0 to 1 transition commands the PNS to clear failsafe state1 to 0 transition has no effect.4 Heartbeat Enable 1 = Enable Heartbeat feature.0 = Disable Heartbeat feature.5 Heartbeat Remote application (host) should toggle this bit to indicate it isalive. When there is no update to this bit for more thanconfigured communication timeout, the PNS treats it as acommunication/application failure and goes to failsafe state.Applicable only when “Heartbeat Enable” in output controlregister is ‘1’.6 – 16 Reserved
