Counter C
Function memory C is a status memory which stores that the counting value exceeds the set value. (Count up status).
①
The program execution result of the counter is stored.
②
Counter counts are stored in the register corresponding to the counter number (elapsed value register).
、
(C0=R1000 C1=R1001)
③
You can reset the count up status and elapsed values with the RSTTC command.
④
There are three types of counter instruction: 4-digit addition (with reset condition), 4-digit addition (without reset
condition), and 8-digit addition/subtraction counter.
⑤
When the power failure hold setting is used, the counter ON/OFF state and elapsed value can be stored even in the
event of a power failure.
(7)
Special relay SP
Functional memory SP is a special internal relay pre-prepared in the system for convenience in creating user programs
such as clocks and flags. On user programs, Special relay SP can only be used as contact conditions.
(8)
Register R
Functional memory R is a data register composed of 16 bits per word used for data storage of data processing instructions,
etc.
①
Also included are elapsed value registers for storing timer elapsed values and counter counts, and special registers
for storing parameter settings and system information.
②
The function memory (status memory) representing the ON/OFF state of one point (bit) is set to one word (16 points
combined) and is assigned a number as register R.
③
Indirect specifications indicating the register number in which the target data is stored in the program are used as the
identification symbol P.
④
When the power failure hold setting is used, register data can be stored even when power is cut off.
