GOAL EtherNet/IP API

In order to enable EtherNet/IP support in GOAL, the goal_eipInit function must be called within the appl_init function. The configuration and creation of a new EtherNet/IP instance is done within the appl_setup function.

static GOAL_EIP_T *pHdlEip;   /**< GOAL Ethernet/ IP handle */

GOAL_STATUS_T appl_init(
    void
)
{
    GOAL_STATUS_T res;                           /* result */

    res = goal_eipInit();
    if (GOAL_RES_ERR(res)) {
       goal_logErr("Initialization of Ethernet/IP failed");
    }

    return res;
}
