Communication example of I/O data exchanges

This section describes an example of I/O data exchanges between the DP-Master and DP-Slaves (with the refresh settings
enabled).

System configuration example

The following system configuration is used in this section.
System configuration
RJ71PB91V No.0
Number and station type
No.0: DP-Master (FDL address 0)
No.1: DP-Slave (FDL address 1)
No.2: DP-Slave (FDL address 2)
No.3: DP-Slave (FDL address 3)
I/O data assignment
I/O data of the DP-Slave (FDL address 1) is assigned as follows.
No. Name I/O configuration information of
slave parameter
(1) Input module Data module 0: Input 1 word
(2) Output module Data module 1: Output 2 words
(3) I/O module Data module 2: I/O 2 words
(4) Output module Data module 3: Output 1 word
(5) Input module Data module 4: Input 2 words
(6) Output module Data module 5: Output 1 word
Data for acquiring Data module 6: I/O 1 word
information
I/O configuration information of slave parameters is set on the DP-Master. ( MELSEC iQ-R PROFIBUS-DP Module User's
