WORD ScanType Scan type
Specifies the type of connection to be used.
Up to two can be selected. However, COS and cyclic
connections cannot be selected at the same time.
Specify 0
× 8000 (32768) for automatic selection.
WORD Output1 Size of output data 1 in bytes 0x00 to 0xC8 (0 to 200)
WORD Input1 Size of input data 1 in bytes 0x00 to 0xC8 (0 to 200)
WORD Output2 Size of output data 2 in bytes 0x00 to 0xC8 (0 to 200)
Set this area to 0 if specifying automatic selection for
the scan type or specifying only one connection.
WORD Input2 Size of input data 2 in bytes 0x00 to 0xC8 (0 to 200)
Set this area to 0 if specifying automatic selection for
the scan type or specifying only one connection.
WORD ConnectAccept Connected/Not connected
Not connected:0xFFFF (65535)
Connected: Some other value
Normally set to 0 (when connected).
Select 0xFFFF (when not connected) if Slaves are to
be added later or reserved in the scan list. When
0xFFFF is selected, I/O communications do not
occur even if the Slave is registered in the scan list.
No communications errors will occur either. Once the
Slave has been added use
SCAN_ConnectSlaveDevice() to start I/O communi-
cations.
WORD HeatBeatTime COS/cyclic send interval time (ms)
Setting range:
0x0000 (0): Default (1 s)
0x000A to 0xFFFF (10 to 65535): 10 to 65,535 ms
The actual HeatBeatTime will be the greater of the
following values:
• The value set here
• Communications cycle time x 2
• 10 ms
WORD Output1PathLen Output 1 connection path size: 0x00 to 0x10 (0 to 16)
WORD Output1Path[16] Output 1 connection path
WORD Input1PathLen Input 1 connection path size: 0x00 to 0x10 (0 to 16)
WORD Input1Path[16] Input 1 connection path
WORD Output2PathLen Output 2 connection path size: 0x00 to 0x10 (0 to 16)
Set this area to 0 if specifying automatic selection for
the scan type or specifying only one connection.
WORD Output2Path[16] Output 2 connection path
WORD Input2PathLen Input 2 connection path size: 0x00 to 0x10 (0 to 16)
Set this area to 0 if specifying automatic selection for
the scan type or specifying only one connection.
WORD Input2Path[16] Input 2 connection path
WORD Reserve Reserved area, so set to 0.
WORD Reserve2 Reserved area, so set to 0.
