2 ppendix : s s s ommands are primarily used to read from and write to the TRIO() module s internal registers. Steps The TRIO() module s internal current count register can be read from or written to if the input is configured for a ounter or Quadrature ounter. Timer values are not accessible. The TRIO() module s internal current output pulse count can be read from or written to only if the pulse output is running ynamic Velocity or ynamic Positioning profiles. Name ommand ode System ommand Error System ommand omplete PL ontrol Outputs ase ddr = V00 (it-of-word) User Specified to use with R/WT Instruction PL Status Inputs ase ddr = V000 (it-of-word) PL ontrol Outputs ase ddr = V00 (ontrol Relay) -0 User Specified to use with R/WT Instruction PL Status Inputs ase ddr = V000 (ontrol Relay) -0 V0. V0. Process ommand V00. 0 NOTE :The -0 PU does not support bit-of-word addressing. The status and control bits must be mapped to control relay words. n example of mapping code is shown on right. SP ction Hex: Read ll Registers Hex: Write ll Registers Hex: Write One Register Hex: Write Reset Value ON if ommand or Parameters are invalid When ON, command has been accepted, clear Process ommand bit Turn ON ommand omplete status bit is returned L OUT L OUT V00 V00 V0 V0 NOTE : For example, irectsoft uses 00. in the ladder code to indicate that you are addressing the second bit of V-memory register V00. The prefix indicates bit-of-word addressing. L Win NI - ounter I/O User Manual, rd Edition
