1 Example project

The location for the ECS SimepleConfig Example is in our Knowledge Base

KB → Software → LFW Host Examples → EtherCAT Slave

For netX90:

2 ECS Sources

Take the netXStudion to open the projcet. The ECS Sources in the ECS SimepleConfig Example are in the folder:

netXStudio_ECSV5_simpleConfig_V2.1.0.0\netX 90 - EtherCAT Slave - simpleConfig V2.1.0.0\Components\cifXApplicationDemoECS\Sources

3 Configuration packet

The ECS Configuration packet is in the file AppECS_DemoApplicationFuction.c

ECSConfigPacket.c

4 Values from ESI file

DeviceInfo values:

#define ECS_PRODUCTCODE_NXEB51_FEATURES                               0x00000038

#define ECS_SECONDARY_VENDORID_HILSCHER                               0xE0000044

#define ECS_REVISIONNUMBER_CIFXMODIFIERMASK                           0x00080004

#define DEV_GROUP_TYPE_INFO                                           "netX"

#define DEV_TYPE_INFO                                                 "NETX ECS Host Example"

#define DEV_NAME_INFO                                                 "NETX ECS Host Example"

need to be same like in ESI file:

Process Data Values:

Choose the number of Input and Output Bytes and tell this the stack in the configuration packet with

  ptConfigReq->tData.tBasicCfg.ulProcessDataOutputSize = sizeof(APP_PROCESS_DATA_INPUT_T); /**< Process Data Output Size from master view */

  ptConfigReq->tData.tBasicCfg.ulProcessDataInputSize = sizeof(APP_PROCESS_DATA_OUTPUT_T); /**< Process Data Input Size from master view */


Change the number of Bytes for RxPdo (Output) and TxPdo (Input) in the ESI file, like in the configuration packet


<RxPdo Sm="2">

          <Index>#x1600</Index>

          <Name>1. RxPDO</Name>

          <Entry>

            <Index>#x2000</Index>

            <SubIndex>1</SubIndex>

            <BitLen>8</BitLen>

            <Name>1 Byte Out (0)</Name>

            <DataType>BYTE</DataType>

          </Entry>

          <Entry>

            <Index>#x2000</Index>

            <SubIndex>2</SubIndex>

            <BitLen>8</BitLen>

            <Name>1 Byte Out (1)</Name>

            <DataType>BYTE</DataType>

          </Entry>

          ........

<TxPdo Sm="3">

          <Index>#x1A00</Index>

          <Name>1. TxPDO</Name>

          <Entry>

            <Index>#x3000</Index>

            <SubIndex>1</SubIndex>

            <BitLen>8</BitLen>

            <Name>1 Byte In (0)</Name>

            <DataType>BYTE</DataType>

          </Entry>

          <Entry>

            <Index>#x3000</Index>

            <SubIndex>2</SubIndex>

            <BitLen>8</BitLen>

            <Name>1 Byte In (1)</Name>

            <DataType>BYTE</DataType>

          </Entry>

          ........


Example ESI file:

10 Byte Output

6 Byte Input

Hilscher NETX90 RE ECS V5.0.X.xml

5 Start Sequenz

  1. Config Stack
  2. Init Config
  3. Start
  4. Stack is in Init State

6 ECM Master

As soon as the ECS Stack is successfully configured and the “Start Communication Request” / “Bus On” is done, the EtherCAT Slave goes in Init State.

The EtherCAT Master now needs to bring the EtherCAT Slave from Init State to Operational State (OP).
