On some BACnet L-INX models, the Modbus RTU and BACnet MS/TP protocols share the
same port. On those models, Modbus RTU can only be used, if BACnet MS/TP is disabled.
Please refer to Table 1 to learn, which BACnet L-INX models have this restriction.
Through the Modbus interface the device can be used to data points to other technologies,
and expose Modbus data points to OPC tags. All AST functions can be used directly on
Modbus data points. Especially trending data and polling for data on Modbus devices has
been optimized for automatic meter reading applications.
For debugging purposes a protocol analyzer is included in the firmware and can be operated
via the Web UI and the configuration software. For more information on how to set up the
device for using Modbus, configuring and using Modbus data points, refer to Chapter 11.
1.6 LIOB
Some L-INX automation server models allow connecting physical I/Os directly to the
device via the LIOB I/O modules. Those modules can be stacked up to the L-INX using the
LIOB Connect feature. The connected I/O modules are automatically identified and coupled
as data points into the L-INX automation server. LIOB modules are available with digital
inputs and outputs, analog inputs and outputs and universal inputs that are configurable.
The I/O modules can be parameterized over the configuration software or the Web UI. All
parameterization data is stored on the L-INX and can be reloaded to the LIOB modules
when needed. The exchange of modules is detected automatically. For more information on
how to setup and use LIOB I/Os please refer to the L-IOB user manual [7].
1.7 L-INX Models
This Section provides an overview of the different L-INX models in Table 1. This table
identifies the different features of the L-INX models. Models that possess a certain feature
have a check mark (
)
in the respective column. If a feature is not available in the particular
model, the column is left blank.
L-INX models with the router option have a CEA-709 router or a BACnet router,
respectively. The LINX-151 has both a CEA-709 router between FT and IP and a BACnet
router between MS/TP and IP.
