Safeguarding Your Plant with AutoSave Change Management Software
WHAT IS AUTOMATION CHANGE MANAGEMENT?
A Change Management System (CMS) is a centralized system that tracks and identifies changes to program logic for devices such as PLCs, CNCs, HMIs, PC control systems, robots, etc. and provides methods for backup and recovery.
WHY DO PROGRAM CHANGES NEED TO BE MANAGED?
Automation devices are complex and incorporate a large amount of plant data in their operation. Adjustments to variables/logic may be minor individually, but are directly linked to machine throughput and uptime.
Make a program change you wish you had not?
If program changes are not managed correctly and the current device program and configuration are lost, it can result in:
Downtime Decreased machine performance Increased safety hazards Decreased quality/visibility
AUTOMATION CHANGE MANAGEMENT SYSTEM KEY FEATURES
• Common central repository of all program changes with automated retrieval The key to rapid recovery is the ability to access and download the correct automation program to the device.
• The ability to detect and notify users of program changes An effective CMS has the ability to interrogate devices and compare the program running in the device to a reference copy in the CMS.
• Secured user and workstation access Each user should be authenticated by the CMS.
• A historical record of changes A CMS will also record details of changes, such as who made the change, when, and from where it was made.
• Non-networked device management
