GPIO / AIO User Guide

Reference Design User Guide

1. Introduction

This document introduces how to setup entire environment for GPIO / AIO application on AX58200 evaluation

platform (TSB + EXB-ADIO boards). The demo application of EtherCAT master side develops by PLC

(Programmable Logic Controller) language through BECKHOFF TwinCAT engineering (XAE). The IDE rely

Microsoft Visual Studio 2010 / 2013. We can execute the application through the mentioned IDE or pure

BECKHOFF runtime package (XAR). The firmware part of EtherCAT slave side develops by C language

through ARM KEIL MDK (Microcontroller Development Kit).

The firmware part mainly handles below affairs:

⚫BECKHOFF SSC (Slave Stack Code)

⚫Hardware access of SSC through SPI interface at MCU side

⚫Simple object form for CIA-401 digital/analog IO

⚫Peripherals (GPIO / ADC / DAC) accessed by EtherCAT PD (Process Data)

The PLC part mainly handles below affairs:

⚫PD mapping / handling by PLC for GPIO / AIO

⚫A demo GUI

2. Requirements

Before starting to setup the environment, we should prepare some software and hardware. Of course, they

are all running based on general desktop PC with windows 7 / 10 operation systems. We list software /

hardware requirements as following:

[Software at EtherCAT master side]

⚫Windows 7 / 10 operation system

⚫Microsoft Visual Studio 2010 / 2013

⚫Beckhoff TwinCAT XAE v3.1.4022.28 or later

Figure 2 - 1

Note: You can download the BECKHOFF TwinCAT here or contact ASIX Electronics Corporation.

3-2 AX58200-EXB-ADIO

AX58200-EXB-ADIO is an expansion board for AX58200 GPIO / AIO application and has below components:

⚫LED for Digital Output –Digital output (8-bit) to the LEDs

⚫DIP Switch for Digital Input –Dip switch to the digital input (8-bit)

⚫Analog Input Pin –You can measure the input voltage of ADC by this PIN

⚫Analog Output Pin –You can measure the output voltage of DAC by this PIN

⚫Variable Resistance –You can adjust input voltage of ADC through this component

⚫ESC Port2 –Port2 of the ESC

⚫Rotary Dip Switch –A rotary dip switch that can assign a 16-bit digits

4. Basic Operation of TwinCAT

Before starting up the AX58200-TSB first time, you MUST download available contents into AX58200

EEPROM first. If there are no available contents in AX58200 EEPROM, the MCU will be reset forcibly

by ESC.

Assume you already installed the BECKHOFF TwinCAT XAE in your environment.

Please follow below sections for EEPROM download.

4-1 Open XAE through Visual Studio 2010 / 2013

Open the XAE by clicking below system tray icon:

Figure 4 - 1

4-2 Project creation & download EEPROM

Any common deploy or applications through TwinCAT XAE all should process under a TwinCAT project. We

create an empty TwinCAT project and scan out etherCAT slave that linked to the master. If you have a

Beckhoff real-time compatible network adapter (ex: Intel I-350) in the system, TwinCAT master can bundle

the adapter as main etherCAT port. If you have 2 adapters, the second adapter can be used for deploy

redundancy. Whatever, you should create a TwinCAT project first for any etherCAT related affairs under

TwinCAT XAE. Please refer to below steps:

⚫Step 1: Click the “New TwinCAT Project…”

Figure 4 - 2

AX58200

GPIO / AIO User Guide

Reference Design User Guide

⚫Step 2: Specify “Name”and “Location”and click “OK”.

Figure 4 - 3

⚫Step 3: Click the “TWINCAT -> Show Realtime Ethernet Compatible Devices…”

Figure 4 - 4

AX58200

GPIO / AIO User Guide

Reference Design User Guide

⚫Step 4: Make sure your network adapter installed BECKHOFF EtherCAT real-time driver

If not installed, please click “Install”.

Figure 4 - 5

⚫Step 5: Please copy the ESI (EtherCAT Slave Information) file “AX58200_GPIO_8Bit_AIO_16bit.xml”

from the BSP directory:

“YOUR_BSP_FOLDER\SampleCode\Ethercat_GPIO_AIO_Reference_Design\For_

TwinCAT\ESI\”

Figure 4 - 6

⚫Step 6: Copy the file to TwinCAT directory: “C:\TwinCAT\3.1\Config\Io\EtherCAT\”

Figure 4 - 7

AX58200

⚫Step 7: Click “TWINCAT -> EtherCAT Devices -> Reload Device Descriptions”.

Figure 4 - 8

⚫Step 8: Plug USB power and connect ESC port0 to TwinCAT master port.

Figure 4 - 9

⚫Step 9: Right-click on “IO / Devices”and select “Scan”.

Figure 4 - 10

⚫Step 10: Choose main network adapter.

Figure 4 - 11

⚫Step 11: Click “Yes”.

Figure 4 - 12

AX58200

⚫Step 12: Click “Yes”.

Figure 4 - 13

⚫Step 13: Double click “Device N (EtherCAT)”and you will see the TwinCAT master scanned out the

EtherCAT slave

Figure 4 - 14

AX58200

GPIO / AIO User Guide

Reference Design User Guide

⚫Step 14: Select the slave, right-click and choose “EEPROM Update…”

Figure 4 - 15

⚫Step 15: Select the “AX58200_GPIO_8Bit_AIO_16Bit”and click “OK”.

Figure 4 - 16

AX58200

⚫Step 16: Wait for progress bar at lower right corner of the TwinCAT screen.

Figure 4 - 17

⚫Step 17: Select “Device N (EtherCAT)”, right-click and choose “Remove”.

Figure 4 - 18

⚫Step 18: Click “Yes”.

Figure 4 - 19

⚫Step 19: Execute “Scan”again (repeat Step 7 ~ 11) and you will see below screen.

Assume AX58200 did not download available firmware with Slave Stack Code yet.

So the state field “INIT INIT_ERR”is properly / reasonable.

Figure 4 - 20

AX58200

GPIO / AIO User Guide

If there is an available firmware with Slave Stack Code in AX58200, you should see below

screen. The “State”field is “OP”mode.
