7. Turn on +5V dc and +15V dc power supplies. Allow 15 minutes
warm-up time for module stabilization.
8. Using an industrial terminal, enter the calibration program
(Figure 5.2) into the PC processor. The PC processor must be in
program mode.
The calibration program in Figure 5.3 can be adapted for use with any
Allen-Bradley programmable controller capable of executing a block
transfer program using block format instructions. This program is written
for a Mini-PLC-2/15 or PLC-2/30 processor.
The calibration program continuously toggles between read and write
block transfers. Be sure that the module address entered in the block
instruction corresponds to the module’s location in the I/O chassis. The
calibration program’s module address is rack 1, module group 4, slot 0.
The block lengths have been set to the default value, 00. The file-to-file
move instruction is used to display dynamic block, loop block and status
block data.
NOTE: The user program must not be operating during calibration
because it will interfere.
