SysCode values returned:
SysInvalidRequest The slot and bit assignment specified is not a valid digital input.
SysOK The function completed successfully.
Example:
DIGINS0B3 : Integer;
…
GetDigin (0, 3, DIGINS0B3);
WriteLn (Port1, "Digin S0B3 status is", DIGINS0B3);
GetDigout
Sets V to the value of the digital output assigned to slot S, bit D. GetDigout sets the value of V to 0 if the output is
on, to 1 if the output is off. Note that the values returned are the reverse of those used when setting an output with
the SetDigout function.
Method Signature:
function GetDigout (S : Integer; D : Integer; VAR V : Integer) : SysCode;
Parameters:
[in] S Slot number
[in] D Bit number
[out] D Digital output status
SysCode values returned:
SysInvalidRequest The slot and bit assignment specified is not a valid digital output.
SysOK The function completed successfully.
Example:
DIGOUTS0B2 : Integer;
…
GetDigout (0, 2, DIGOUTS0B2);
WriteLn (Port1, "Digout S0B2 status is", DIGOUTS0B2);
SetDigout
Sets value of the digital output assigned to slot S, bit D, to the value specified by V. Set V to 1 to turn the
specified output on; set V to 0 to turn the output off.
Method Signature:
function SetDigout (S : Integer; D : Integer; V : Integer) : SysCode;
Parameters:
[in] S Slot number
[in] D Bit number
[in] D Digital output status
SysCode values returned:
SysInvalidRequest The slot and bit assignment specified is not a valid digital output.
SysOutOfRange The value V must be 0 (inactive) or 1 (active).
SysOK The function completed successfully.
Example:
DIGOUTS0B2 : Integer;
…
DIGOUTS0B2 := 0;
SetDigout (0, 2, DIGOUTS0B2);
5.7 Fieldbus Data
