2 DESCRIPTION
LPC-2.MC9 Smarteh flagship controller offers improved performance, scalability and a wide range of
new features within a single compact SOM based package. Simple and innovative concept, where
most competitors require multiple products to deliver similar functionality. Main module based on
ARM architecture processor running Linux based operating system (OS) adds more computing power,
more control and additional interface connection offering capability for future core SOM module
upgrade without hardware changes.
In addition, LPC-2.MC9 is designed to connect additional input, output modules on the left
(connector K2) and communication modules on right bus (connector K1).
LPC-2.MC9 has integrated USB programming and debugging port, connection for intelligent
peripheral modules and Ethernet Modbus TCP/IP port for network connectivity. It can be used as a
stand-alone controller or connected to remote input/output devices via the CANopen interface. This
interface also allows you to communicate with other main modules (with a CANopen interface).
LPC controller and hardware configuration is done using Smarteh IDE programming software, used to
design user configuration selecting from a wide range of module (up to 71) in a single configuration.
This software provides you with a simple entry in the IEC programming languages such as:
•Instruction List (IL)
•Function Block Diagram (FBD)
•Ladder Diagram (LD)
•Structured Text (ST)
•Sequential Function Chart (SFC).
This provides a large number of operators such as:
•Logic operators such as AND, OR, ...
•Arithmetic operators such as ADD, MUL, ...
•Comparison operators such as <,=, >
Programming software is used to create test and document a project. Functions for analog
processing, closed-loop control and function blocks such as timers and counters simplify
programming.
1 Some modules are subject to power consumption and number limitation, this limitations are handled directly in the Smarteh
IDE not allowing users to add more modules.
For proper system configuration and data allocation please refer to Smarteh IDE software help menu.

4 OPERATION
After installation done only by qualified persons LPC-2.MC9 main module must be configured and
programmed with the appropriate user program using Smarteh IDE software.
Smarteh IDE software allows user to configure main module to its own requirements.
LPC-2.MC9 comes with factory predefined network settings:
MAC: is unique for every unit produced. This value can be also found on the label attached
on the housing of the unit.
IP: default value is 192.168.19.222
MASK: default value is 255.255.255.0
Gateway, Primary DNS, Secondary DNS: default 0.0.0.0
RTC unit
The main module has a real-time clock unit that can be accessed by user program via functions
described in the Smarteh IDE manual. RTC unit has super capacitor backup with retention time is
estimated up to 14 days.
RTC provides date and time information, while additional alarming function is also supported.
Modbus TCP/IP slave unit
Modbus TCP slave has 1024 addresses in each memory section.
Coils: 00000 to 01023
Discrete Inputs: 10000 to 11023
Input Register: 30000 to 31023
olding Registers: 40000 to 41023
Supports up to 5 connections to the slave units (defined with MaxRemoteTCPClient parameter).
ighest scan rate is 100 ms.
CANopen unit
The CAN interface is designed as a CANopen interface in compliance with the CIA specification.
CANopen unit consists of Master (CAN1) and Slave (CAN2) communication ports. They are
independent, thus can be connected to two different CAN networks at the same time.
The ports can operate at baud rates 50 kbps, 125 kbps or 250 kbps.
It follows the internationally standardized (EN 50325-4) CAN-based higher-layer protocol for
embedded control systems. Advised rules and concepts by this standard must be followed to fulfill
the conditions and so achieving normal operation and results.
The structure of the network as cable type and lengths, baud rates, number of the nodes and
termination must be taken into account within the recommendations and requirements, when
designing the network.
The bus network can consist of at least one Master and at list one Slave node by the standard, but it
is advised that with increased number of nodes, the Master node fastest interval is extended. Below
are two examples:
Example1: network with 1 master and 9 slaves, every slave have defined 32 (4x8) byte of data and
baud rate 125 kbps. Fastest Cycle time for this configuration is 50 ms.
4

Longo programmable controller LPC-2.MC9
Example2: network with 1 master and 4 slaves, every slave have defined 4 byte of data and baud
rate 250 kbps. Fastest Cycle time for this configuration is 5 ms.
5 millisecond is the fastest recommended cycle time. It is recommended to power-up all the nodes
on the same network at the same time, if some or all nodes had been reprogrammed (to reinitialize
the communication properly).
Figure 2: Master and Slave wiring diagram
Devices connected over CAN bus connection are wired in bus topology (serial). Appropriate wires
must be connected together ( I- I, LO-LO, GND-GND). CAN1 port is used when the device acts as
Master, CAN2 port is used when the device acts as a Slave. Master or Slave devices can be positioned
on any place inside the bus.
Devices connected over CAN bus connection must be properly terminated. Termination must be
made on first and last CANopen device on the bus.2
Main module operation modes
LPC-2.MC9 operates in two modes, normal run mode and programming mode. Switching between
modes is done by using switch S1 (Table 4.).
Program Mode
In Program Mode the CPU does not execute the application program or update the output modules.
The primary use for Program Mode is to enter or change an application program.
Run Mode Operation
In Run Mode, the CPU executes the application program and updates the I/O system. You can
perform many operations during Run Mode.
Some of these include:
•Monitor and change I/O point status
•Update timer/counter preset values
•Update Variable memory locations
2 Wires connected to the module must have cross sectional area at least 0,14 mm². Use twisted-pair cables of type CAT5+ or
better, sheilding is recommended. Minimum temperature rating of wire insulation must be 85 °C. Galvanic isolation of 2500
V DC between CAN1, CAN2 and rest of the PLC circuit is provided.

With Smarteh IDE also in Run mode is possible to stop executing program and change the
application.
SD Card
The memory card is used for data storage.
