PROGRAMMING GUIDE
This chapter is intended to offer the programmer additional information about some of the functionalities and units integrated in this module.

Basic functionalities

RTC unit
For RTC back-up and for Retain variables there is Super Capacitor instead of battery integrated inside PLC. This way, replacement of the discharged battery is avoided. The Retention time is minimum 14 days from the power down. RTC time provides date and time information.

• Coils: 00000 to 09999
• Discrete inputs: 10000 to 19999
• Input register: 30000 to 39999
• Holding registers: 40000 to 49999

Supports up to 5 connections to the slave units (defined with MaxRemoteTCPClient parameter).
Highest scan rate is 100 ms.
Modbus RTU master unit
When configured for Modbus RTU Master mode, the the LPC-3.GOT.012 functions as a master device,controlling the communications with other slave devices such as sensors, inverters, other PLCs, etc.
LPC-3.GOT.012 sends Modbus RTU commands to and receives Modbus RTU responses from the slave devices.
Following commands are supported:

• 01 – Read Coil Status

• 03 – Read Holding Registers
• 04 – Read Input Registers
• 05 – Write Single Coil
• 06 – Write Single Register
• 15 – Write Multiple Coils
• 16 – Write Multiple Registers

Note: each of this commands can read/write up to 246 bytes of data. For analog (Input and Holding registers) this means 123 values, while for digital (Statuses and Coils) this means 1968 values. When higher quantity of data is required, LPC-3.GOT.012 can execute up to 32 same or different supported commands simultaneous.
Physical layer: RS-485
Supported baud rates: 9600, 19200, 38400, 57600 and 115200bps Parity: None, Odd, Even. Stop bit: 1

Smarteh RS485 bus for connectivity with LPC-2 system Port COM1 is used for communication with LPC-2 slave modules. All communication settings are configured in SmartehIDE software program.
BACnet IP unit
When configured for BACnet IP (B-ACS), following commands are supported:
Data Sharing

• Dynamic Object Binding-B (DM-DOB-B)
• Device Communication Control-B (DM-DCC-B)
• Time Synchronization-B (DM-TS-B)
• UTCTimeSynchronization-B (DM-UTC-B)

For more information, please contact producer.

CANopen unit

• CANopen unit consists of Master and Slave communication ports. They are independent, thus can be connected to two different CAN network 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 fulfil 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:
• Example 1: network with 1 master and 9 slaves, every slave have defined 32 (4×8) byte of data and baud rate 125 Kbps. Fastest Cycle time for this configuration is 50 ms.
• Example 2: 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 ms 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).

RUN/STOP Switch

• Run: Status RUN status LED “on” indicate that the user graphical application is up and user program is running.
• Stop: When the switch is turn to STOP state, the RUN status LED is “off” and application is stopped.
• PLC task cycle time
• Main PLC task interval (under Project tab -> Resource Tasks Interval) time → → is not recommended to be set lower than 50 ms.

WiFi configuration

1. Connect terminal to the PC via USB connector and switch ON power supply.
2. Using web browser, type default IP address 192.168.45.1 and port 8009.
3. Click on “Settings”.
4. The Settings page opens. In the “Network Settings for eth() interface (wired)” section select “Disabled”, from the “Configuration type” drop-down menu.
