5 . IT operations for factory systems
If the factory network goes down, production stops immediately. The IT infrastructure supporting a connected EMS facility must be architected for high availability, extreme security, and rapid disaster recovery.
This chapter establishes the critical IT operations required to keep the factory running. We detail the maintenance of server uptime, cybersecurity protocols to protect customer Intellectual Property, and the management of edge computing hardware deployed on the shop floor.
- 5.1 MES rollout method: pilot, line, factory & cutover checklist
Deploying a new MES or ERP module acts as a transplant of the manufacturing facility's nervous system. A "Big Bang" deployment (switching everything at once) is generally considered a highly risky str...
- 5.2 Change & release management
A manufacturing facility operates with different constraints than a software startup. A "Move fast and break things" approach can unfortunately translate to stopping the line and impacting revenue. Th...
- 5.3 Support model: L1/L2/L3, incident response, monitoring
A deployed system without a defined support architecture is a dormant failure waiting for a trigger. In a 24/7 manufacturing environment, relying solely on reaching the original developer is not a sca...
- 5.4 Backup & disaster recovery
A system that cannot be reliably recovered introduces unacceptable risk. In manufacturing, uptime is critical. If the MES database corrupts, the impact extends beyond an IT outage; it affects the run-...
- 5.5 Access control matrix + audit trails
Security in a manufacturing environment requires vigilance to prevent both external threats and internal, accidental data corruption (such as an operator unintentionally modifying a Master Routing). T...
