| Communication Interface (T8151B) |
The T8151B communication interface provides a comprehensive range
of communication services for the controller, effectively
minimizing communication loading of the TMR processor. This module
enables seamless communications with other Trusted systems,
engineering workstations, and third-party equipment.
The user-configurable module supports multiple communication media
and features dual Ethernet ports, four serial ports accessible via
the T8153 communications interface adapter, plus a front-accessible
diagnostic port.
Installable in any single-width slot of a controller or expander
chassis, this module supports peer-to-peer communication only when
installed in the controller chassis. It offers ten Modbus (RTU)
protocol connections via the Ethernet TCP/IP stack (default IP port
2000) and one fixed programming toolset connection (port 6000).
Additional features include support for up to ten Modicon open
Modbus TCP connections on port 502 and dual redundant +24V DC power
supply from the chassis backplane.
- High-speed data acquisition and transmission
- Hot-spare capability for uninterrupted operation
- Continuous diagnostics with fault indicators
