Setting Item Details
Master/Slave Set the operating mode (i.e., DeviceNet master or slave) for the 260IF.
Set to the same value as the value set using 260IF setting switch SW1
(X1).
MAC ID The MAC ID is the DeviceNet MAC ID (i.e., DeviceNet address) of
the 260IF. Set to the same value as the value set using 260IF setting
switches 2 and 3.
MAC ID column The MAC ID field is the DeviceNet MAC ID (i.e., DeviceNet address)
for I/O allocation. MAC ID column are set automatically in order start-
ing from 00.
D Input enable/disable sets whether or not the Controller CPU exchanges
I/O data with the 260IF. Select it to disable I/O data exchange.
INPUT Set the start address of the input area (input register IWxxxx) allocated
to the relevant device. Specify using a hexadecimal word address.
BSIZE Displays in bytes the size of the output area (input register IWxxxx)
allocated to the relevant device. Specify from 1 to 256 (in decimal) for
1 slave. For example, if setting 3 bytes from IW1100 and 1 byte from
IW1102, the registers are used as shown below.
Register Address F to 8 7 to 0
IW1100H
IW1101H
IW1102H
IW1103H
D Output enable/disable sets whether or not the Controller CPU
