Sample Application
A test engineer uses Series 988s to control the temperatures of several
automated test chambers. His computer is linked to the controllers
through its EIA/TIA-422 serial communications port. His computer pro-
gram monitors the temperatures of the chambers and initiates automatic
test sequences when certain program parameters are met. After complet-
ing a sequence, the computer loads the next temperature to the controller.
The computer periodically interrogates each controller for its process tem-
perature, set point and alarm status. This information is stored on a disk
to provide test verification data for the completed products.
