Firmware Installation Procedures

Changing the firmware on the processor module involves minor

mechanical disassembly and reassembly of the controller.

Appropriate precautions should be taken to prevent

electrostatic discharge damage to the electronic components.

Wear a grounding strap and place components on static-free

grounded surfaces only.

A small flathead screwdriver is needed.

All control parameters will revert to factory defaults when

installing a new flash memory chip containing controller

firmware. Take a “snapshot” of the current configurations

using AnaWin3 before removing the flash memory chip.

The flash memory chip also stores the logic program if one has

been programmed. After replacing a flash memory chip, the

logic program should be downloaded to the controller using

LogicPro.

CAUTION!

Be sure to take antistatic precautions.

1. Save snapshot. The logic program will be erased.

2. Power down the controller and system, including heaters

etc.

3. Remove the power connection to the processor module and

any cables between the modules and terminal boards.

4. Note and label cable locations.

5. Remove the PPC-2000 system from the DIN rail or panel.

6. Make sure the red top and bottom module latches on the

processor module are in the unlocked position (pushed

toward the back of the module.)
