Appendix 5 Ethernet App5-33
Read Words from Memory Card Memory
int HKEtn_ReadCardMemory(WORD *dp,unsigned short Wordcnt,int FileNo,int
RecordNo,DWORD addr,char *lpAddr,int DFlag=1)
This function is retained until data is transferred from the V7 series.
• Parameters
*dp Target block pointer
Wordcnt Word count to be transferred (max. 2000 words)
FileNo File number
RecordNo record number
addr Top memory address to be read
*lpAddr IP address shown as a string of characters separated by dots
Example: “192.168.XXX.XXX”
DFlag 0, 1, 2 (Refer to page App5-31.)
• Return values
Success TRUE
Failure FALSE
Error details Get using HKEtn_GetLastError ().
Read Bits from PLC Memory
int HKEtn_ReadPlcBitMemory(int *lpOnFlag,int DeviceType,DWORD addr,int BitNo,char
*lpAddr)
This function is retained until PLC data is transferred from the V7 series.
• Parameters
*IpOnFlag Returns the bit status. 0: OFF 1: ON
DeviceType Address of the device to be read (Refer to “Chapter 2” to “Chapter 33.”)
addr Top memory address to be read
* For YOKOGAWA or YASKAWA PLCs, specify a number “−1” for the
address (addr).
Example: D400 → 399 D25 → 24
BitNo Bit number to be read
Example 1: When accessing to D20-05 of MITSUBISHI PLC
DeviceType 0
addr 20
BitNo 5
Example 2: When accessing to M20 of MITSUBISHI PLC
20 ÷ 16 = 1 ... 4
DeviceType 6
addr 1
BitNo 4
*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 ().
