The practicality of the PM3328B-6-1-3-E 80026-524-01 application is improved while controller redundancy and redundant controllers are housed in the same chassis. The redundant controllers operate in parallel, checking status several times throughout the operating cycle, allowing the backup controller to continuously monitor the status of the primary controller, thus ensuring a quick and undisturbed switchover if necessary. Redundant controllers are also able to perform firmware upgrades online.

The engineering tools included with the PM3328B-6-1-3-E 80026-524-01 provide a comprehensive project development environment with modules, tools and a complete set of diagnostic tools. This development environment centralises project engineering including configuration of I/O (instrument indexing) and control strategies. A comprehensive library of functional architectures is available for advanced process control requirements. All IEC 61131-3 programming languages are supported (Ladder Logic, Structured Text, Instruction List, Sequential Function Chart and Functional Structure Chart), plus flowchart support.

Network redundancy on the PM3328B-6-1-3-E 80026-524-01 helps ensure stable and consistent communications. The controller has two high-speed Ethernet ports that use fault-tolerant Ethernet redundant communications. Each port can be connected to a separate LAN and is constantly monitored for integrity. If the primary port detects a network failure, traffic is switched to the other LAN to keep communications open.
