2 DESCRIPTION
LPC-2.CX1 is a communication module with a port for RS-485 communication. It's main feature is
being a gateway for Modbus RTU or other UART protocols, exchanging data with the main module,
where all of data is being interpreted. It also equipped with a MP3 player and an audio amplifier for
an external speaker connection.
LPC-2.CX1 is controlled and powered from the main module (e.g. LPC-2.MU1, LPC-2.MC9, ...) via
Right internal bus.

4 OPERATION
LPC-2.CX1 module can be controlled from main PLC module (e.g. LPC-2.MC9). Module parameters
can be read or written via Smarteh ID software. To use the LPC-2.CX1 module in your Smarteh ID
programming software configuration, you must select the universal module LPC-2.Cxx.
LPC-2.CX1 module can also be controlled by the Modbus RTU Slave main module (e.g. LPC-2.MU1).

4.2 Modbus RTU and SmartehIDE Parameters – Modbus RTU mode
By specifying the first parameter Protocol type, Parameter number 1, Modbus RTU holding register
93 High byte (93.H), determine the type of communication on the RS-485 communication port.
Based on this parameter, the content of further communication parameters is determined. The
parameters are described in the tables below.
If protocol type Modbus RTU master driver is selected use the tables in this chapter numbered
from 2 to 21.
In the first column named Reg. are Modbus RTU registers. These are used for controlling LPC-2.CX1
module from the Modbus RTU Slave main module (e.g. LPC-2.MU1).
In second column named Par. there are SmartehID parameter indexes. These are used for
controlling LPC-2.CX1 module from the main module (e.g. LPC-2.MC9).

4.3 Modbus RTU and SmartehIDE Parameters – Universal mode
By specifying the first parameter Protocol type (Parameter number 1, Modbus RTU holding register
93.H), determine the type of communication on the RS-485 communication port. Based on this
parameter, the content of further communication parameters is determined. The parameters are
described in the tables below.
If protocol type Universal UART is selected use the tables in this chapter numbered from 22 to 26.
In first column named Reg. are Modbus RTU registers. These are used for controlling LPC-2.CX1
module from the Modbus RTU Slave main module (e.g. LPC-2.MU1).
In second column named Par. there are SmartehID parameter indexes. These are used for
controlling LPC-2.CX1 module from the main module (e.g. LPC-2.MC9).
