Write Bits to Internal Memory
int HKEtn_WriteInternalBitMemory(int DeviceType,DWORD addr,int BitNo,int OnFlag,char
*lpAddr)
This function is retained until write completion is received from the V7 series.
(It is reset on receipt of write completion to the internal memory.)
• Parameters
DeviceType 0: $u 1: $s 2: $L 3: $LD 4: $T
addr Top memory address to be written
BitNo Bit number to be accessed
OnFlag 0: OFF 1: ON
*lpAddr IP address shown as a string of characters separated by dots
Example: “192.168.XXX.XXX”
• Return values
Success TRUE
Failure FALSE
Error details Get using HKEtn_GetLastError ().
Write Bits to Memory Card Memory
int HKEtn_WriteCardBitMemory(int FileNo,int RecordNo,DWORD addr,int BitNo,int OnFlag,char
*lpAddr)
This function is retained until write completion is received from the V7 series.
(It is reset on receipt of write completion to the memory card memory.)
• Parameters
FileNo File number
RecordNo Record number
addr Top memory address to be written
BitNo Bit number to be accessed
OnFlag 0: OFF 1: ON
*lpAddr IP address shown as a string of characters separated by dots
Example: “192.168.XXX.XXX”
• Return values
Success TRUE
Failure FALSE
Error details Get using HKEtn_GetLastError ().
Others Functions
Initialization Function
int HKEtn_Init(unsigned short Port=10000,int Retry=3,int RecvTime=2,int RecvTime2=10)
Creates a socket.
• Parameters
Port Set 10000 or above.
Retry Number of send retrials
RecvTime Receive timeout
RecvTime2 Receive timeout 2
• Return values
Success TRUE
Failure FALSE
Error details Get using HKEtn_GetLastError ().
*1 When “HKEtn_Recvfrom()” is used, the time for [RecvTime] is used for timeout judgment.
*2 When “HKEtn_Readxxx” or “HKEtn_Writexxx” is used, both the times for [RecvTime] and
[RecvTime2] are used for timeout judgment.
Total time for timeout = [RecvTime] x [RecvTime2] x [Retry] (seconds)
