● Connecting a machine interface device, such as an operator terminal or a text-
based operator terminal, to the TC Modular.
● Executing firmware flash upgrades.
● 1200 bps to 115.2 Kbps communication is supported.
NOTE:
The communication speed of the port must match the communication speed of the
device connected to it.
USB Device Port
The USB Device port supports a generic serial interface for an HMI or Tool device. The
USB Device port does not support firmware flash upgrades.
10B/100B Ethernet Port
The 10B/100B Ethernet port provides a path for commands and information
transmitted between field panels inside a firewall. This port provides both full- and half-
duplex 10Base-T or 100Base-TX compliant communications over a BACnet/IP
Automation Level Network (ALN). The highest possible communication speed is
automatically detected and selected.
RS-485 Port
The RS-485 port provides a path for commands and information transmitted between
field panels. This port provides communications over a BACnet MS/TP Automation
Level Network (ALN). The communication speed is set during startup.
The RS-485 port provides half-duplex, asynchronous serial RS-485 communications
over shielded twisted pair cable. The RS-485 connector is labeled + – to indicate the
positive and negative connections. is a reference pin.
FLN Support
The Siemens Industry Field Level Network (FLN) can consist of devices that
communicate over an RS-485 connection using MS/TP.
● Each field panel supports a total of 96 FLN devices.
● The devices may be grouped in any combination on the FLN ports as long as the
total number of FLN devices on the field panel does not exceed 96.
Expansion Module Overview
The Expansion Module provides the hardware connection for Field Level Network
(FLN) devices including:
● Siemens Industry FLN
● Communications Drivers to Non-Siemens Networks
Siemens Industry FLN
Using the Triple RS-485 Expansion Module, the TC Modular supports one RS-485
network of BACnet MS/TP devices.
