LLExec LxWin

LLExec for Acontis LxWin usage instructions

Prerequisites

Configure a LxWin RTOS machine (currently tested on LxWin 7.1.02.04) with a dedicated ethercat capable network card (optional) and a virtual network to enable TCP/IP communication between Windows and LxWin.(See official LxWin documentation)

WARNING: Ethercat has been tested only with Intel network cards using e1000e linux driver. (eg. Intel I210 Series)

Installation

• Extract the LLExec_x.y.z_LxWin.zip file into a windows folder, let's say c:\data\plc
• Within LxWin, the directory "/mnt/rtfiles" is shared with Windows under "%APPDATA%\acontis_technologies\workspaces\default\Rtfiles". Make a new directory (eg: Rtfiles\plc) and copy there all files from c:\data\plc except for "LLExecStart_LxWin.exe" and "ProtocolData.dll"
• Move the new plc directory with all files and subdirs to /tmp/plc

Current version: LLExec_2.20.17_LxWin

Execution

• From Windows side launch "LLExecStart_LxWin.exe".

(WARNING: This must be called always before starting the RTOS or at least before starting LLExec for the first time in a RTOS session).

• Start the LxWin RTOS
• (optional for EtherCAT): From LxWin side execute "LxWin_EthercatInit.sh" to configure Intel network device in LxWin and load the e1000e driver. (This script have to be executed only one time after the system boot and before starting LLExec).

(WARNING: If not using Intel network cards or e1000e driver, you have to modify the LxWin_EthercatInit.sh according to the device name and linux driver of your card).

• Launch "runLLExec.sh" to actually start LLExec.

(Without license it will start in DEMO mode, if you need a licence key please ask us specifing if you need Ethercat license too, since Ethercat functionality requires a separate key along with LLExec license key.

LogicLab usage

• Execute LogicLab
• Create a new project using the LLExec PLC runtime (LxWin) target (A new project will be created with just a counter variable that increments itself)
• Click on menu "On-Line->Setup Communication" to configure a GDB connection using the virtual IP address of LxWin (typically 192.168.157.2), port 5000.
• Click on menu "On-Line->Connect" to connect to target (or use the dedicated button in the toolbar)

Ethercat Master example (optional)

• Import an .esi file with the command "Tools->Import ESI".
• Click on resources tab of LogicLab, then select the "Ethercat" node and enable it with the checkbox.
• Right click on the "main network" ethercat node and select "add" to add your imported ethercat device.
• A new node for the ethercat device will appear, configure it as you like.
• Save, compile and download the project to the target.
