PanelTemp(Dest,Integ)
PanelTemp is the keyword. Two parameters follow: Dest, a destination variable
name in which the temperature value is stored; and Integ, of a length of time to
integrate the measurement. To place the panel temperature measurement in the
variable RefTemp, using a 250 µs integration time, the syntax is as shown in
CRBasic example Measurement Instruction Syntax
(p. 158).
Measurement Instruction Syntax
'This program example demonstrates the use of a single measurement instruction. In this
'case, the program measures the temperature of the CR800 wiring panel.
Public RefTemp 'Declare variable to receive instruction
BeginProg
Scan(1,Sec,3,0)
PanelTemp(RefTemp, 250) '<<<<<<Instruction to make measurement
NextScan
EndProg
7.6.3.14.2 Argument Types
Most CRBasic commands (instructions) have sub-commands (parameters).
Parameters are populated by the programmer with arguments. Many instructions
have parameters that allow different types of arguments. Common argument types
are listed below. Allowed argument types are specifically identified in the
description of each instruction in CRBasic Editor Help.
• Constant, or expression that evaluates as a constant
• Variable
• Variable or array
• Constant, variable, or expression
• Constant, variable, array, or expression
• Name
• Name or list of names
• Variable, or expression
• Variable, array, or expression
7.6.3.14.3 Names in Arguments
Table Rules for Names (p. 159) lists the maximum length and allowed characters for
the names for variables, arrays, constants, etc. The CRBasic Editor pre-compiler
will identify names that are too long or improperly formatted.
