TableApp.22 Special register
• Following programmable controller CPU module RUN, 1 is added each
second
• Count repeats from 0 to 32767 to -32768 to 0
• Stores value n of 2n second clock (Default is 30)
• Setting can be made between 1 and 32767
• Stores value n of 2nms clock (Default is 30)
• Setting can be made between 1 and 32767
• Incremented by 1 for each scan execution after the CPU module is set to
RUN.
(Not counted by the scan in an initial execution type program.)
• Count repeats from 0 to 32767 to -32768 to 0
• Incremented by 1 for each scan execution after the CPU module is set to
RUN.
• Count repeats from 0 to 32767 to -32768 to 0
• Incremented by 1 for each scan execution after the CPU module is set to
RUN.
• Count repeats from 0 to 32767 to -32768 to 0
• Used only for low speed execution type programs
