CS1W-HIO01: 0.08 ms max.
CS1W-HCP22/HCA22: 0.1 ms max.
The above figures are for operation under the following conditions:
1. Data exchange with the CPU Unit is performed using the allocated
words in the CIO Area only.
2. The Programming Device connection switch is set to OFF.
3. With the HCP22/HCA22, Measurement Mode is not being used.
4. With the HCA22, analog output is refreshed immediately.
None (The Unit's built-in I/O points are used for the Input and Output
Areas given below.)
12 bits: IR 000 (IR 00000 to IR 00011)
The Unit's built-in input points are allocated to these bits (fixed
allocations).
Note IR 00000 to IR 00003 can be used either as normal input bits or
for interrupt inputs (in Input Interrupt Mode or Counter Mode).
8 bits: IR 001 (IR 00100 to IR 00107)
The Unit's built-in output points are allocated to these bits (fixed
allocations).
1,088 bits (68 words): IR 002 to IR 049 (IR 00200 to IR 04915),
IR 200 to IR 219 (IR 20000 to IR 21915)
These bits have no specific functions and can only be used in the
program.
568 bits (36 words): SR 220 to SR 255 (SR 22000 to SR 25507)
These bits have specific functions.
Note SR 230 to SR 234 and words SR 235 to SR 239 are used for
exchanging general-purpose data with the CPU Unit.
448 bits (28 words): AR 00 to AR 27 (AR 0000 to AR 2715)
These bits have specific functions.
8 bits: TR 0 to TR 7
These bits temporarily store the ON/OFF status of an instruction
block for branching.
512 bits (32 words): LR 00 to LR 31
These bits are for exchanging general-purpose data with the CPU
Unit. (Data can be exchanged cyclically with user-set words in the
CPU Unit. Up to 32 words of data can be input or output. The word
allocation are specified in the Unit Setup Area.)
256 points: TIM/CNT 000 to TIM/CNT 255 (The same numbers are
used for timers and counters.)
When using the CNT and CNTR instructions, at power interruption or
when the mode is switched, present counter values are held (with
super-capacitor backup) at the values immediately before power was
interrupted or the mode was switched. When other instructions are
used, the data in the TIM/CNT Area is cleared.
6,144 words: DM 0000 to DM 6143
Data in this area can be read or written in word (16-bit) units. It is
held (with super-capacitor backup) at power interruptions or when
the mode is switched. Writing can be performed with instructions or
from the Programming Device.
Note By turning ON bit SR 25200, it is possible to save all the data in
the range DM 0000 to DM 6143 to flash memory. The data is
read using the XFER instruction.
2,048 words: EM 0000 to EM 2047
Data in this area can be read or written in word (16-bit) units. It is
possible to specify whether the data is held (with super-capacitor
backup) at power interruptions or when the mode is switched. Writing
can be performed with instructions or from the Programming Device.
