6.4.2 PROFIBUS-DP
The configuration data format is applicable for the both formats of standard and special
identifications. However, it is necessary to have the configuration data size in the RSEL system
and the I/O size used in PROFIBUS-DP aligned.
● Standard Identification Format
● Special Identification Format

6.4.3 EtherCAT
In case of use of EtherCAT master supporting only the slave specified fixed PDO mapping such
as CJ1W-
NC□81 / NC□82 manufactured by Omron, set the bits 28 to 31 to 1h in the parameter
below. (e.g. C80000h → 10C80000h)
However, the maximum number of points should be 256 points for input and 256 points for output.
No. Parameter Name Input range Unit Remarks
121 Network attribute 2 C80000h
Bits 28 to 31: EtherCAT PDO mapping type
(0: Variable,1: 32Byte Fixed)
6.4.4 EtherNet/IP
● In EtherNet/IP communication, it cannot be used when the used Port No. 2,222 (UDP Port)
and 44,828 (TCP Port and UDP Port) are blocked by the firewall in the communication path.
● There is a concern that stable communication cannot be established if a repeater hub is used
to have the cyclic (remote I/O) communication in EtherNet/IP because it could increase the
communication load in the network and could cause collision frequently. Use a switching hub.
