Explanation
• The number of CPU modules that comprise the multiple PLC system is
stored. (1 to 3, Empty also included)
• The CPU module types of No. 1 CPU to 3 and whether the CPU
modules are mounted or not are stored.

TableApp.21 Special register
Explanation
• 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
