Firmware/Operating System Upgrade
Introduction
Enclosed in this package is a firmware/operating system upgrade for 
your SLC 5/03 or SLC 5/04 processor. Take anti-static precautions 
when upgrading the firmware.
If you upgrade an SLC 5/03 or SLC 5/04 processor, you receive 
anomaly fixes as well as added functionality. During the upgrade, the 
ladder logic program inside the processor is erased. Therefore, the 
first step in upgrading the firmware/operating system is to save the 
processor’s ladder logic program.
This product is CE compliant for all applicable directives when 
product or packaging is marked.
Installation Procedure
Follow these instructions carefully. Refer to page 3 for component 
placement information.
1. Save the current user program to your hard drive using your
programming software, to a memory module, or to a 1747-PSD 
Program Storage Device.
2. Remove the communication cable between the processor and
your programming terminal.
ATTENTION
!
The Flash EPROMs are electrostatic sensitive devices. 
Do not handle without proper grounding 
precautions. Do not install PROM with power 
applied to the SLC 5/03 or SLC 5/04 processor.
IMPORTANT
The user program is cleared as part of the 
firmware/operating system upgrade process. 
You must restore your program after loading 
the upgrade. Also, all communication ports are 
returned to the default parameters.
