HscInfo_IsChannelEnabled

Checks if high-speed counter channel is enabled

This instruction returns TRUE if the high-speed counter channel specified by iChannel has been enabled in the system registers and is supported by the selected PLC type.

Parameters

Input

iChannel (INT)

High-speed counter channel:

FPS: 0, 2

FP-X R: 0, 1

FP-X 16K C14T: 0, 1, 2

FP-X 32K C30T, C60T: 0, 1, 2, 3

FP0R: 0, 1, 2, 3

FP0: 0, 1

FP-e: 0, 1

Output

VAR_OUT (WORD): TRUE if the channel specified by iChannel is enabled
