Display of Hex Value
During the calibration procedure, hex values transferred to and from the
PID module can be displayed by using the industrial terminal in data
monitor mode. With the processor in program mode and the cursor on the
file-to-file move instruction, press (DISPLAY) (1). The block files will
be displayed in hex notation starting with word W01 in position 001.
The status words which must be monitored during calibration have the
same number as the file positions. Disregarding the prefix W, the
following status words can be monitored at the positions stated in
Table 5.A.
These words can be displayed by pressing the key sequence
(DISPLAY)(0)(6)(4). Word 064 will be displayed at the top of the
industrial terminal screen.
