Triconex 4609 Advanced Communication Module (ACM)

Triconex 4609 Advanced Communication Module (ACM)
The Model Triconex 4609 Advanced Communication Module (ACM) acts as an inter-face between a Tricon controller and a Foxboro Intelligent Automation (I/A) Series system, appearing to the Foxboro system as a safety node on the I/A Series Nodebus. The ACM communicates process information at full network data rates for use anywhere on the I/A Series system, transmitting all Tricon aliased data (including system variables and system aliases) and diagnostic information to operator workstations in display formats that are familiar to Foxboro operators. The ACM makes the following functions available to the I/A Series:

• Handles critical I/O points and passes results to the I/A Series using the Object Management Database (OMDB)
• Processes Tricon alarms and propagates them to user-defined I/A Series destinations (consoles, printers, etc.)
• Propagates Tricon alarms as I/A Series system messages
• Reads/writes aliased data to satisfy I/A Series requests
• Time synchronization from the I/A Series environment
• Reads Tricon diagnostics for display by the I/A Series workstation
• Write protection to lock out changes to the Tricon controller from all I/A Series sources
• Hot-spare capability for uninterrupted communication with the I/A Series Nodebus The ACM also supports the following Triconex protocols and applications on external host PCs connected to a separate BNC port (labeled NET 2):
• Tristation protocol for the TriStation 1131 software
• TSAA protocol for Triconex applications
• TSAA/TCP (UDP/IP) for userwritten applications on external hosts
