Computing the Cycle Time
Section 2-7
Related Words
The average cycle time for the past eight cycles can be read from the CX-Pro-
grammer.
Note The following methods are effective in reducing the cycle time.
• Place tasks that do not need to be executed on standby.
• Use JMP-JME instructions to skip instructions that do not need to be exe-
cuted.
2-7-4 I/O Refresh Times for PLC Units
CP-series Expansion Unit and Expansion I/O Unit I/O Refresh Times
Name Addresses Description
Maximum Cycle
Time A262 and
A263 These words contain the maximum cycle time in
increments of 0.1 ms. The time is updated every
cycle and is recorded in 32-bit binary (0 to FFFF
FFFF hex, or 0 to 429,496,729.5 ms). (A263 is
the leftmost word.)
Present Cycle Time A264 and
A265 These words contain the present cycle time in
increments of 0.1 ms. The time is updated every
cycle and is recorded in 32-bit binary (0 to FFFF
FFFF, or 0 to 429,496,729.5 ms). (A265 is the
leftmost word.)
