Read Board Temperature
This command returns the temperature of the thermocouple cold-junction compensa-
tion sensors (if 7409TB termination boards are connected to the 7429). Depending on
the command opcode used, temperature data will be returned from either the high
7409TB (channels 8-15) or low 7409TB (channels 0-7).
A 16-bit value is returned, scaled to 0.10°C/bit. Ordinarily, this command is used either
as a diagnostic tool or to monitor the ambient temperature.
COMMAND:
(64)
RESPONSE:
(CHAN 0-7 7409TB TEMP MSB),(CHAN 0-7 7409TB TEMP LSB)
COMMAND:
(65)
RESPONSE:
(CHAN 8-15 7409TB TEMP MSB),(CHAN 8-15 7409TB TEMP LSB)
Example: Two 7409TB termination boards are connected to the 7429. This code
segment will read and display the low 7409TB (connected to channels 0 through 7)
temperature in degrees centigrade.
