Read Board Temperature
This command returns the temperature at the optional 7409TC termination board. Useful for
monitoring the temperature of thermocouple reference junctions, this function is also a good
debugging aid during 518 installation. The returned temperature value is scaled to 0.10 degrees
C/bit.
If no 7409TC is connected to the 518, the Read Board Temperature command will return a
meaningless value.
COMMAND: (64)
RESPONSE: (BOARD TEMP MSB), (BOARD TEMP LSB)
EXAMPLE:
‘ Read and display the 7409TC temperature in degrees F:
CALL Send518Byte (BasePort%, 64) send opcode to 518
Temp! = Read518Word (BasePort%) / 10! ‘read response & convert to degrees C
DegreesF! = 1.8 * Temp! + 32.0 ‘convert to degrees F
PRINT DegreesF! ’display temperature on CRT
