Random Access Memory (RAM)
Synchronous Dynamic Random Access Memory (SDRAM) is the working memory of
the TC Modular. When the TC Modular has booted and is operating normally, the
TALON firmware, the PPCL control program, the point database, and trend data have
been transferred from Flash ROM. Information stored in RAM, such as the point
database or PPCL, may be viewed, modified, deleted, activated, or deactivated from
an operator terminal by any high-level authorized user. In the event of a power loss,
the contents of RAM are kept intact by a backup battery.
TC Modular RAM size cannot be upgraded in the field.
The program length, number of database points, and number of trend entries is limited
only by available memory.
Communication Connections
The TC Modular Series operates on the Automation Level Network (ALN) or the Field
Level Network (FLN).
● When connected to the ALN, the TC Modular uses a logical point firmware
database to communicate directly with TC Compact, and other nodes on the
network.
● When connected to the MS/TP FLN, the TC Modular operates as a third-party
BACnet device.
The TC Modular provides the following communication connections:
● HMI and Tools
● Network
– 10B/100B Ethernet port
– RS-485 port
– USB Host port
● TC Modular Expansion Module
● TX-I/O Bus
The following connections and features are available when communicating on a
BACnet/IP Automation Level Network:
● Ethernet port
● RS-485 Port
● USB Host port
● BACnet Field Panel Web Server support: Web-based Graphical User Interface
(GUI) compatible with BACnet® networks. Ideal for small or remote facilities to
monitor and control the Building Automation System.
HMI and Tool Ports
● The HMI port provides a connection to a laptop computer for local operation and
engineering.
● The USB Device port supports a generic serial interface for an HMI or Tool
connection.
Human-Machine Interface (HMI)/Tool Port
The Human-Machine Interface (HMI)/Tool port provides RS-232 compliant
communications through a quick-connect RJ-45 jack. The HMI port supports the
following functionality:
