Section 1-1
Advanced Processing • Either high-speed or normal-speed execution can be selected for basic
instructions. The execution time for basic instructions in High-speed Exe-
cution Mode is approximately twice as fast as the time in Normal Execu-
tion Mode. (The program must be approximately 1 Kword or less to use
High-speed Execution Mode.) (Example for LD instruction: Normal Execu-
tion: 0.4
m
s; High-speed Execution: 0.2

s)
• Faster execution of CTBL and other instructions using table data can be
achieved by not holding the EM Area status when power is turned OFF.
Coordinating Operation
with the CPU Unit • Data can be exchanged in three different areas of memory shared with
the CPU Unit to perform handshaking and other operations without pro-
gramming a special interface.
• Ten words of the CIO Area in the CPU Unit are shared with SR Area
Words in the Customizable Counter Unit.
• Up to 90 words of the DM Area in the CPU Unit can be shared with
user-set words in the Customizable Counter Unit.
• Up to 32 user-set words in the CPU Unit can be shared with LR Area
words in the Customizable Counter Unit.
• External interrupt tasks in the CPU Unit can be executed by programming
the MCRO instruction in the Customizable Counter Unit. The Customiz-
able Counter Unit can thus activate programming in the CPU Unit
depending on the control status of the Customizable Counter Unit to syn-
chronize processing with other Units.
Special I/Os that Can
Support Various
Applications • 1 high-speed analog input (CS1W-HCA12-V1)
High-speed analog input (A/D conversion time = 50
m
s) is possible. It sup-
ports 0 to 10 V, 1 to 5 V,
-
10 to 10 V, 0 to 5 V, and 4 to 20 mA. This
enables the control supporting the analog input from the displacement
and pressure sensors through the linear sensor.
• 2 high-speed analog outputs (CS1W-HCA12-V1)
High-speed analog output (D/A conversion time = 50
m
s) is possible. It
supports 0 to 10 V, 1 to 5 V,
-
10 to 10 V, 0 to 5 V. The combination of this
and the use of servo drivers of an analog input type enables the speed
control, torque commands, etc. in addition, it can be used for the inverter
control (frequency commands).
• 1 input for taking in the absolute encoder output data (CS1W-HCP22-V1/
HCA22-V1/HCA12-V1)
With this input, it is possible to take in the absolute encoder output data
directly from the servo drivers manufactured by OMRON, etc. Since it
enables the feedback input of the absolute value information, the analog
output mentioned above can be used for position control.
Ladder Library Function
(All -V1 Models) These units has the built-in ladder programs. It is possible to encapsulate the
programs as the ladder library. The ladder library is saved to the Flash mem-
ory in the unit. The encapsulation of the programs to the library enables the
"protection of the ladder software assets from the third party" and "execution
of the ladder software functions quasi-without programming".
Back-up Function (All -V1
Models) Through the bit manipulation from the CPU unit, it is possible to back up
(write) or restore (read) the data of the unit to or from the memory card. With
the use of CS1-H CPU units, the data can be backed up or restored through
the simplified back-up operation on the front panel of the CPU unit.
