1. Compactlogix VS SLC 500
Control logix processors are more powerful, faster and a lot more flexible.
The programming is entirely tag based.
The entire tag database, including tag names and tag comments are downloaded into the PLC

2. RSLogix 5000 and RSLogix 500
Both programs can use the same open instance of RSLinx at the same time.
RSLogix 500 is used with the earlier generation SLC500 and MicroLogix 1500/1200/1100/1000 family of Programmable Logic Controllers.
RSLogix 5000 is used with the new generation of "ControlLogix" Programmable Automation Controllers.

3. RSLogix 5000
Rslogix 5000 is used to program all five Rockwell Automation Logix platforms:
ControlLogix
CompactLogix
FlexLogix
SoftLogix5800
DriveLogix.

4. Connecting hardware Devicenet variable speed drives
Ethernet wireless control
PanelView control / monitoring of equipment
Peer to Peer connectivity

5. CompactLogix

6. Compact I/O has a unique modular rackless design, which both contributes to system cost savings and reduces parts inventory
Its communication bus, typically found in the I/O rack, is instead integrated into each Compact I/O module

7. SLC 500 family

8. Why Choose the SLC 500?
Controls hundreds of thousands of processes around the world — amusement park rides to pharmaceutical processing
15 M processors and 12 M, I/O modules installed worldwide
Used by over 75% of companies comprising the Dow Jones Industrial Average (DJIA)
Large choice of I/O available from Rockwell Automation and third party companies, making these products appropriate for almost any application
Over 100,000 customers trained in the U.S. alone, making this product one of the most understood of its type
