Method Signature:
function SetSPVunder (SP : Integer; V : Real) : SysCode;
Parameters:
[in] S P Setpoint number
[in] V Underrange
SysCode values returned:
SysInvalidSetpoint The setpoint specified by SP does not exist.
SysInvalidRequest The setpoint specified by SP has no VUNDER parameter.
SysOK The function completed successfully.
Example:
SP4VUR : Real;
…
SP4VUR := 26.4
SetSPVunder (4, SP4VUR);
StartBatch

5.6 Digital I/O Control
In the following digital I/O control functions, slot 0 represents the J2 connector on the indicator CPU board and
supports four digital I/O bits (1–4). Digital I/O on expansion boards (slots 1–14) each support 24 bits of I/O (bits
1–24).
GetDigin
Sets V to the value of the digital input assigned to slot S, bit D. GetDigin sets the value of V to 0 if the input is on,
to 1 if the input is off. Note that the values returned are the reverse of those used when setting an output with the
SetDigout function.
Method Signature:
function GetDigin (S : Integer; D : Integer; VAR V : Integer) : SysCode;
Parameters:
[in] S Slot number
[in] D Bit number
[out] D Digital input status
