(b) Head device number
Specify the head device number of the programmable controller CPU device
memory to be assigned to the MODBUS device.
The upper limit of the setting is the number resulted from "each device’s upper
limit minus 8 points".
POINT
If F000
H
(buffer memory) is specified for the device code, the error status read
buffer memory (address: 000F
H
) will be the error status read target. (No other
buffer memory can be set.)
In this case, make the setting as indicated below.
• Set "0000
H
" to the head device number (address: 000B
H
).
• Store the error status data in the error status read buffer memory
(address: 000F
H
).
