Situation Extra CPU Unit Cycle Time
and Duplex CS1D-LCB05D
Operation Cycle Time
Operation on
CPU Unit
• Power ON to PLC.
• When the Duplex
Unit's initialize switch is
turned ON.
• When CPU Unit opera-
tion started.
• When data transferred
to CPU Unit (user pro-
grams, PLC Setup, I/O
tables, CPU Bus Unit
system settings area
transfers, online editing,
and timer/counter set-
ting changes)
CS1D-CPU65H: 1.83 s max.
CS1D-CPU67H: 2.13 s max.
The extra time depends on
the contents of the LCB05D
function block data, as shown
in the following examples.
Example 1: For 40 function
blocks, 5 sequence tables,
and 30 user link tables:
CS1D-CPU65H: 0.40 s max.
CS1D-CPU67H: 0.73 s max.
Example 2: For 200 function
blocks, 50 sequence tables,
and 600 user link tables:
CS1D-CPU65H: 1.26 s max.
CS1D-CPU67H: 1.59 s max.
Example 3: For 500 function
blocks, 200 sequence tables,
and 2,400 user link tables:
CS1D-CPU65H: 1.83 s max.
CS1D-CPU67H: 2.13 s max.
