Engineers will appreciate the native Ethernet connectivity of the INESM01. This module eliminates the need for external gateway devices. Consequently, users can connect INFI 90 systems directly to plant networks and enterprise applications.

Furthermore, the module supports multiple industrial protocols simultaneously. The INESM01 handles Modbus TCP for SCADA integration, HTTP for web-based monitoring, and FTP for data file transfers. This versatility simplifies system architecture and reduces component count.

Network Architecture and Security

The INESM01 provides 10/100 Mbps auto-negotiating Ethernet connectivity. An RJ45 connector with integrated LEDs shows link status and activity. The module supports up to 32 simultaneous client connections for multi-user access.

Users can configure network parameters including IP addressing, subnet masks, and gateway settings. The module stores these configuration parameters in 1 megabyte of non-volatile flash memory. This retention ensures settings persist through power cycles.

System Integration and Data Exchange

You can install this Ethernet server module in any INFI 90 rack system. The INESM01 communicates with the system master through the Module Bus. This integration allows operators to access real-time process data from standard web browsers.

The module consumes only 4.2 watts from the backplane power supply. This low power draw allows dense module configurations per rack. For reference, other Bailey INFI 90 communication modules share this same form factor and installation method.

Diagnostics and Operational Reliability

The INESM01 includes comprehensive diagnostic features for network monitoring. Status LEDs indicate power, communication activity, and network link status. The module performs continuous self-checks to detect configuration errors and network faults. These diagnostics simplify troubleshooting and ensure reliable Ethernet connectivity.
