9.6. Real-time Ethernet Driver Control Interface

9.6.1. emonIoCtl - EC_IOCTL_ISLINK_CONNECTED

EC_IOCTL_ISLINK_CONNECTED

Determine whether the link between the stack and the first slave is connected.

Parameters

pbyInBuf – [in] Should be set to EC_NULL
dwInBufSize – [in] Should be set to 0
pbyOutBuf – [out] Pointer to EC_T_DWORD. If value is EC_TRUE link is connected, if EC_FALSE it is not.
dwOutBufSize – [in] Size of the output buffer in bytes
pdwNumOutData – [out] Pointer to EC_T_DWORD. Amount of bytes written to the output buffer.

Returns

EC_E_NOERROR or error code

struct EC_T_LINK_CONNECTED_INFO

Public Members

EC_T_BOOL bConnected: [out] MAIN or RED link detected

EC_T_BOOL bSendEnabled: [out] Send enabled on MAIN or RED

EC_T_BOOL bMainConnected: [out] MAIN link detected

EC_T_BOOL bMainMasked: [out] MAIN link not used for sending, because topology changed delay not elapsed yet

EC_T_BOOL bRedConnected: [out] RED link detected

EC_T_BOOL bRedMasked: [out] RED link not used for sending, because topology changed delay not elapsed yet

9.6.3. emonIoCtl - EC_LINKIOCTL…

The generic control interface provides access to the main network adapter when adding EC_IOCTL_LINKLAYER_MAIN to the EC_LINKIOCTL parameter at dwCode.

EC_T_DWORD dwCode = (EC_IOCTL_LINKLAYER_MAIN | EC_LINKIOCTL_GET_ETHERNET_ADDRESS);

9.6.4. emonIoCtl - EC_LINKIOCTL_GET_ETHERNET_ADDRESS

Provides MAC addresses of main or red line.

emonIoCtl - EC_LINKIOCTL_GET_ETHERNET_ADDRESS

Parameter

dwInBufSize: [in] Should be set to 0
pbyOutBuf: [out] Pointer to MAC address buffer (6 bytes)
dwOutBufSize: [in] Size of the output buffer in bytes (at least 6)
pdwNumOutData: [out] Pointer to EC_T_DWORD. Amount of bytes written to the output buffer.
