HSCE

The HSCE instruction is used for controlling and reading the HSC counter.

Languages supported: Function block diagram, ladder diagram, structured text.

This instruction applies to the L20E, L50E, and L70E controllers.

HSCE parameters
Parameter	Parameter Type	Data Type	Description
Enable	Input	BOOL	TRUE: The HSCE initiates the function block and the plug-in HSC module. Accumulator = InitAcc. Status of HSCE will be reset. Rate1 = 0, Rate2 = 0. FALSE: The Accumulator is updated by reading from the plug-in module. Done, Active, Error = FALSE while ErrorID = 0, Rate1, Rate2 = 0.
Channel	Input	HSCE_CHANNEL	The HSCE channel.
Run	Input	BOOL	For HSCE to count the operational state. TRUE: HSCE counts the pulses. FALSE: HSCE stops the counting.
Reset	Input	BOOL	TRUE: All outputs are cleared and accumulator. Rate1 and Rate2 are also cleared to 0. Plug-in HSC module status clear. The priority of Reset input is higher than the input of Run.
Done	Output	BOOL	TRUE: When HSCE Enable is TRUE and no error is detected. FALSE: When HSCE Enable is TRUE but Run is FALSE.
Active	Output	BOOL	TRUE: When HSCE Enable is TRUE, Done is TRUE and Run is FALSE. FALSE: When HSCE Enable is TRUE but Run is FALSE.
Rate1	Output	REAL	Current Pulse Rate in user unit per second (Per Pulse method).
Rate2	Output	REAL	Current Pulse Rate in user unit per second (Cyclic method).
TPValue	Output	LINT	Accumulator Value capture when touch probe is triggered.
OutputSts	Output	UINT	HSC plug-in Physical and Virtual Output status and is only applicable for HSC counter 0. Bit 0: Output 0 (Physical Output Status) Bit 1 to 15: Output 1 to Output 15 (Virtual Output Status)
Status	Output	UINT	HSC status information.
Error	Output	BOOL	Indicates an error occurred.
ErrorID	Output	UINT	When an error occurs, ErrorID contains the error codes.
