Using High-Speed Outputs 147PTOX Run Status (RS)Sub-ElementDescriptionAddress Data Format Range Type User ProgramAccessRS - Run Status PTOX:0/RS bit 0 or 1 status read onlyThe PTOX RS (Run Status) bit is controlled by the PTO sub-system. It canbe used by an input instruction on any rung within the control program.The RS bit operates as follows:• Set (1) - Whenever a PTO instruction is within the run phase of theoutput profile.• Cleared (0) - Whenever a PTO instruction is not within the runphase of the output profile.PTOX Accelerating Status (AS)Sub-ElementDescriptionAddressDataFormatRange Type User ProgramAccessAS - Accelerating Status PTOX:0/AS bit 0 or 1 status read onlyThe PTOX AS (Accelerating Status) bit is controlled by the PTOsub-system. It can be used by an input instruction on any rung within thecontrol program. The AS bit operates as follows:• Set (1) - Whenever a PTO instruction is within the accelerationphase of the output profile.• Cleared (0) - Whenever a PTO instruction is not within theacceleration phase of the output profile.PTOX Ramp Profile (RP)Sub-ElementDescriptionRP - Ramp ProfileAddress Data Format Range Type User ProgramAccessPTOX:0/ bit 0 or 1 control read/writeRPThe PTOX RP (Ramp Profile) bit controls how the output pulsesgenerated by the PTO sub-system accelerate to and decelerate from theOutput Frequency that is set in the PTOX function file (PTOX:0.OF). Itcan be used by an input or output instruction on any rung within thecontrol program. The RP bit operates as follows:Publication 1766-RM001A-EN-P - October 2008
