Finally, Profinet and EtherNet/IP deterministic network integration requirements are managed via specific communication coprocessors when utilized in integrated automation architectures.
Frequently Asked Questions
Q: What is the failover behavior if the primary controller experiences a fault?A: In a redundant pair, the secondary controller monitors the heartbeat of the primary. Upon detection of a primary fault, the secondary transitions to the active state instantaneously to prevent interruption of the process control loop.Q: Are there specific thermal requirements for operation at ambient temperatures above 50 deg C?A: Yes. Forced air cooling is required when the operating environment exceeds 50 deg C to ensure the heat dissipation of the 80486DX4 microprocessor and internal circuitry remains within specified safe limits.
