Debug for 565 Operations
To change the value of a word, move the cursor to the right side of the
equals sign. Number keys only are functional for entering values. Real
numbers must be used in these fields.
Two additional functions are available in the DEBUG operation for creating
loop and analog alarm value tables. These are accessed by pressing the
BLDCHT (F6) function key. When this key is pressed, the following function
keys are available:
The new function keys are the LOOPWD (F7) and APV (F8) function keys.
The LOOPWD function key allows you to place loop parameters into the
chart. The parameters which may be placed in the chart are the following:
LMN (loop output), LPV (process variable), LERR (loop error), LKC (loop
gain), LTD (loop rate), LTI (loop reset), and LMX (loop bias). These
parameters will appear at the bottom of the screen when the LOOPWD
function key is pressed. After the parameter is chosen, it will appear in the
chart.
The APV (F8) function key is for placement of process variable for analog
alarms into the chart. After the function key is pressed, select the desired
analog alarm number. After that, continue building or changing the chart as
desired. When the chart is complete, press the EXIT function key.
