Selection and Procurement Notes
Redundancy Configuration:
For critical process applications (e.g., refining, continuous chemical production), it is recommended to purchase both K01 and K02 units to enable full CPU redundancy.
Compatibility Check:
Ensure that the system’s 800xA / AC 800M software version is 6.0.2 or later to guarantee full functionality.
Accessories:
When purchasing, confirm that TP830 baseplates, TB807 terminators, RCU-Link cables, and backup batteries are included to avoid downtime due to missing components.
