[Setting 3: Setting of All Connected Station Patterns]
To I/O Parameters No.605 and 606, set whether to connect all the stations (Station No.0 to 63)
in the IA Net network by inputting 0: Not to Use (Not Connected) or 1: Connected.The setting
value is calculated in the hexadecimal system with the bit patterns of 0 and 1 described above.
The relation between each bit and station number is as explained below:
x I/O Parameter No.605 “IA Net All Connected Station Patterns (31-00)”
x I/O Parameter No.606 “IA Net All Connected Station Patterns (63-32)”
Caution 1) With the settings of these parameters, a judgment is made to see a link error.
In case these parameters are not set properly, the judgment of a link error
cannot be executed correctly.
2) An extension I/O unit occupies four stations with multiples of 4 as the top
station number. Pay attention not to duplicate the station number when
assigning in the shared memory.
Example Shown below is an example for setting for the network construction as shown
