1. Preset value setting Function Block
(1) Preset value setting Function Block of GN (HSCC-PRE)
- Preset value setting Function Block sets count start value of HSC module. To change Count, execute Enable Preset after
Preset value setting Function Block acts.

Remark
(1) Input variable ‘MADDR’ of XGI/XGR FB indicates internal memory. Constant or Global variable is inputted. If we refer to
above example, “_F01_CH0_PRESET” is Global constant indicating “02”. Namely, if you input “02” at “MADDR”, result of
XGI/XGR FB is same.
(2) If you use “PUT_DINT” instead of “PUT_DWORD”, preset action is same. At this time, data type of input variable “DATA”
becomes DINT.
(3) Not Preset value setting FB (HSCC_PRE) but also Mode setting function (HSCC_NOD), Auxiliary function setting function
(HSCC_AUX), Comparison setting function (HSCC_CMP), Count read function (HSCC_CNT), Operation information setting
function (HSCC_WR), Operation status read function (HSCC_RD), Comparison output setting function (HSCC_OUT) apply
to (1), (2).
(4) When writing conversion program, if input enters REQ and next input is connected with DONE, execution status of
previous instruction should complete to be used as input of next instruction. If it is error status, it doesn’t operate.
(5) In case of XGR CPU, HSC module should be equipped at extension base.
