LCR.iQ Product Manual > Appendix B: Data Types

For data types D, F, SI, SL, SS, UI, UL, US, and V, the least significant byte of the data is stored at the lowest address with each subsequent byte being stored at the next incremented address. For example, a two byte unsigned short equal to 1,000 and placed at offset 4 in a message or record would be stored as an E8h at offset 4 and a 03h at offset 5.

Type	Name	Description
A	ASCII Character	Contains a one byte ASCII character. The number of characters stored in the field is Size.
AZ	ASCIIZ String	Contains a NUL terminated string of ASCII characters. The maximum length of the string is Size-1.
B	Boolean	Contains a Boolean value of TRUE or FALSE.
D	Double Floating Point	Contains an eight byte floating point number in IEEE-754 format.
F	Floating Point	Contains a four byte floating point number in IEEE-754 format.
LF	LCR Flow Rate	Contains a signed four byte integer in the range -2147483648 to 2147483647 with an implied decimal point defined by the decimals field in the record.
LL	LCR List	Contains a one byte unsigned integer in the range of 0 to 255.
LV	LCR Volume	Contains a signed four byte integer in the range -2147483648 to 2147483647 with an implied decimal point defined by the decimals field in the record.
SB	Signed Byte	Contains a one byte signed integer in the range -128 to 127.
SI	Signed Integer	Contains a signed integer in which the range is operating system dependent. On 16-bit machines, it is a two-byte signed integer in the range -32768 to 32767. On 32-bit machines, it is a four-byte signed integer in the range -2147483648 to 2147483647.
SL	Signed Long	Contains a four byte signed integer in the range -2147483648 to 2147483647.
SS	Signed Short	Contains a two byte signed integer in the range -32768 to 32767.
ST	Structure	Data element is a structure that varies depending on the structure definition.
UB	Unsigned Byte	Contains a one-byte unsigned integer in the range of 0 to 255.
UI	Unsigned Integer	Contains an unsigned integer in which the range is OS-dependent. On 16-bit machines, it's a two byte unsigned integer in the range 0 to 65535. On 32-bit machines, it's a four byte unsigned integer in the range 0 to 4294967295.
UL	Unsigned Long	Contains a four byte unsigned integer in the range 0 to 4294967295.
UN	Union	Data element is a union. The contents vary with the union definition.
US	Unsigned Short	Contains a two-byte unsigned integer in the range 0 to 65535.
