TempScan / MultiScan User’s Manual 889897 API Command Reference A-33
When the unit is inputting or outputting data, it first references the current reading format. For example, if
format is 0 (Engineering Units), it will then reference the current settings of the engineering units and then
perform the necessary conversion. However, data readings are only converted to the specified engineering units
if the associated channel type is a channel that supports those engineering units. For example if the specified
channel is a volts channel and the engineering units is
0 ( °C), then the reading will be interpreted as volts, not a
temperature in °C.
The following table shows the effect of the Set Data Format ( F ) command on reading input/output formats for the
commands and queries over which it has control.
Reading Formats
Commands Engineering Units Binary Counts
High/Low Byte Low/High Byte
C,C?,L,L?,U8 Engineering Units Engineering Units Engineering Units Counts
R,R#,U4,U5,U13 Engineering Units Binary (High/Low) Binary (Low/High) Counts
For more information on data formats, see section Data Format Configuration in the chapter System
Configuration.
EXAMPLES
PRINT#1, “OUTPUT07:F0,0X” ‘ Set the Engineering Units to °C and the
reading format to Engineering Units
