7) Function block (HSCST)
Function block
Description
Input
REQ: Execute the HSC function block
Ch: Set the HSC channel (0~3)
SV: Set Value (32 bit)
Setting range (-2,147,483,648 ~ 2,147,483,647)
Output
DONE: Turns on after the F/B is executed with no error
Stat: Indicates the operation status of F/B
CV: Saving area of the current value
OUT: On when the current value is over than preset value
Off when the current value is less than preset vlaue
CY: On when ‘Carry’ occurs
BORR: On when ‘Borrow’ occurs

(1) Functions
•
When input condition turns on, corresponding high speed counter is enabled.
•
When input condition turns off, high speed counter stop counting and turns output point off . The current value is retained.
•
The high speed counter can counts from -2,147,483,648 to 2,147,483,647(binary 32 bits)
•
When current value is greater than set value, output point F17*(* is channel number) turns on and it turns off when
current value is less than set value.
•
If current value is greater than 2,147,483,647, carry flag F18* turns on and and it turns off when input condition turns off.
If HSC designated as ring counter, carry flag is set when current value reaches set value.
•
If current value is smaller than -2,147,483,648, borrow flag F19* turns on and and turns off when input condition turns off
If designated as ring counter, if current value is 0, borrow flag is set at next pulse’s rising edge and current value goes ‘set
value –1’(in down counter mode)
(2) Error code
Code
Error
Corrective actions
H 10
Mode setting error
When Ch0 is set as 2-Phase, Ch 1 can’t be used and Ch3 can’t be
used if Ch2 is set to 2-Phase.
H 11
Ring counter setting error
Adjust the range of ring counter within 2 ~ 2,147,483,647.
H 12
SV2 setting error
Set SV2 greater than SV1 if zone comparison set is selected.
H 13
Ring counter and SV2 setting error
Adjust the range of ring counter within 2 ~ 2,147,483,647 Set SV2
greater than SV1if zone comparison set is selected
Ex.) When the counter setting value of CH2 is -123, the error code H11 is saved in STAT.
