1.9 ms
Equivalent to CS1-H for all
instructions not requiring syn-
chronization. Execution time
is longer for instructions
requiring synchronization,
including IORF, DLNK, IORD,
IOWR, PID, RXD, FREAD,
and FWRIT. Refer to SEC-
TION 9 CPU Unit Operation
and the Cycle Time for
details.
The cycle time will be
increased for any cycle in
which duplex initialization is
required. Refer to SECTION
9 CPU Unit Operation and the
Cycle Time for details. Set the
maximum cycle time in con-
sideration of this increase.
Approximately 8 ms, but
duplex initialization is
required after online editing
(see above).
Only the normal execution
mode is supported.
Duplex CPU Systems
0.5 ms (normal mode)
0.4 ms (Parallel Processing Mode)
There are no instructions with longer
execution times than those for the
CS1-H.

(There is no need to consider the
time required for duplex initializa-
tion.)
Approx. 8 ms
(No precautions in converting from
the CS1-H.)
The CS1-H also supports Parallel
Processing and Peripheral Servicing
Priority Modes. (No precautions in
converting from the CS1-H.)
Single CPU Systems
0.3 ms (normal
mode on CS1-H)
0.2 ms (Parallel
Processing Mode
on the CS1-H)
0.5 ms (CS1)

CS1-H CPU Units:
Approx. 8 ms
(CHU6@)
The CS1-H also
supports Parallel
Processing and
Peripheral Servicing
Priority Modes.
