4.2.3 Configuration Status (M8040 ~ M8059 and D8040 ~ D8059)
M8040 ~ M8059 are reserved. The configuration bytes in D8040 ~ D8059 define the amount of
data which is exchanged between the corresponding I/O units/blocks, special function blocks
and the DP-master.
*1 This value shows as following Figure.
Ex.1 10 hex = 1 byte (8 bit) inputs not consistent
Ex.2 63 hex = 4 word outputs not consistent

Diagnostic Device Name Description
D8040 ( )
Lower 8 bits Configuration data 1 *1
The data registers D8040~D8055 display the
actual configuration of the node station. After
power on, when the 32DP-IF is in the search
baud rate state or in the wait configuration
state, these data registers contain the default
configuration data.
