1-4-2 Faster Execution Times
Instruction Execution Time Basic instructions in the C200HS are executed in as little as !@2 of the time re-
quired in the C200H. Other instructions are executed in just !@3 to !@8 of the time.
END Processing Time The time required for the cycle’s overhead processes depend on the system
configuration, but these processes are executed in about !@4 of the time required
in the C200H.
I/O Refreshing Time The I/O refreshing time has been reduced for all units, as shown in the following
table.
I/O Unit Time Required for Refreshing
Standard I/O Units
!@3 of the C200H I/O refreshing time
Group-2 High-density I/O Units
!@3 of the C200H I/O refreshing time
Special I/O Units
$@5 of the C200H I/O refreshing time
1-4-3 Larger Instruction Set
Advanced programming is facilitated by the 225 special instructions available
with the C200HS-CPU01-E, C200HS-CPU01-EC, C200HS-CPU03-E,
C200HS-CPU21-E, C200HS-CPU21-EC, and C200HS-CPU23-E, or the 229
special instructions available with the C200HS-CPU31-E and C200HS-
CPU33-E. In addition, programming has been simplified by the addition of con-
venient instructions and macro functions. The new instructions and functions
are covered in detail in the C200HS Operation Manual (W235).
1-4-4 Expanded Number of I/O Points
Two Expansion I/O Racks can be connected to a CPU Rack to comprise a total of
three Racks. This allows for a total of 240 I/O points, for example, when 8-point
I/O Units are used, or 480 I/O points when 16-point I/O Units are used.
In addition, a Remote I/O System can provide a maximum of 800 points with
Slave Units or 512 points with Optical I/O Units.
1-4-5 Wide Selection of Special I/O Units
C200HS Systems can be configured in a variety of ways, using High-density I/O
Units, High-speed Counters, Position Control Units, Analog I/O Units, Tempera-
ture Sensor Units, ASCII Units, Voice Units, ID Sensor Units, Fuzzy Logic Units,
Cam Positioner Units, and so on.
1-4-6 Improved Interrupt Functions
Scheduled Interrupts The C200HS’s scheduled interrupt function has been improved so that the inter-
rupt interval can be set in 1 ms units rather than the 10 ms units in the C200H.
When the interrupt mode is set to C200HS mode, the interrupt response time is
only 1 ms max. (excluding the input ON/OFF delays). When a Communications
Unit is used with the C200HS-CPU31-E/CPU33-E CPU, the interrupt response
time is 10 ms max.
Input Interrupts Up to 8 interrupt subroutines can be executed by inputs to a C200HS-INT01 In-
terrupt Input Unit mounted to the C200HS. When the interrupt mode is set to
C200HS mode, the interrupt response time is only 1 ms max. (excluding the in-
put ON/OFF delays). When a Communications Unit is used with the C200HS-
CPU31-E/CPU33-E CPU, the interrupt response time is 10 ms max.
