The controller can transfer HART protocol from intelligent instrument to the computer running equipment asset management software, allowing remote maintenance and calibration. HART protocol data and diagnostics can also be directly used for control applications, reducing debugging time, downtime and maintenance process costs.
The practicability of the application is improved by the redundant performance of the controller, which is installed in the same backplane. Redundant controllers operate in parallel, and check the state many times in the whole operation cycle, so that the backup controller can continuously monitor the state of the main controller, so as to ensure rapid and undisturbed switching when necessary. The redundant controller can also upgrade the firmware online.
Network redundancy helps to ensure the stability and consistency of communication. The controller has two high-speed Ethernet ports and uses fault-tolerant Ethernet redundancy communication. Each port can be connected to a separate LAN and its integrity can be monitored continuously. If the main port detects the network failure, the communication will be switched to other LAN to keep the communication smooth.
