Design and Energy Storage
This unit stores minimal energy in small filter capacitors. A watchdog timer resets the controller on software faults. The processor runs a real-time operating system for deterministic behavior. Surface-mount technology boosts reliability in industrial environments. Furthermore, this controller includes LED indicators for each communication port.
Installation and Connectivity
You can mount this module into any INFI 90 rack slot. It connects to field devices via rear-panel serial ports. Configuration software runs on a standard Windows PC. Consequently, you complete the setup within a few minutes. Finally, DIP switches assign the controller address on the network.
Performance and Data Management
This unit consumes only 5 watts during normal operation. Its 20 MHz processor handles 64 nodes per communication port. Thus, you get reliable data exchange for large distributed systems. The controller buffers up to 1,000 messages locally. This module also performs automatic error checking on all transmitted data.
Typical Applications
Use this controller module for managing remote I/O communication links. It also excels at bridging between multiple INFI 90 networks. Many plants select this unit for plant-wide data distribution tasks. The compact module design saves valuable rack space effectively. Finally, redundant configuration options provide fault-tolerant communication paths.
