Remote I/O Setup Procedure
The system is configured only with the remote I/Os of Modbus/TCP
EtherNet/IP, with the I/O port
numbers being specified according to fixed port assignment.
4.2.1 Configuration
with
Modbus/TCP
EtherNet/IP Only (No expansion I/O board)
The following settings are applicable when the system is configured only with the remote I/Os of
Modbus/TCP
EtherNet/IP and the standard I/O ports are mapped on Modbus/TCP EtherNet/IP
without connections to any external devices via expansion I/O boards.
[I/O parameters]
No.

14
Number of ports using network
I/F-card remote input
n 0~256
Specify the Modbus/TCP remote DI bits by a multiple
of 8 (8
n 256).
15
Number of ports using network
I/F-card remote output
m 0~256
Specify the Modbus/TCP remote DO bits by a
multiple of 8 (8
n 256).
(Note) When word registers are to be used in Modbus/TCP, set the remote I/O head numbers (I/O port start
numbers: I/O parameters 2 and 3) on a 16-bit boundary, and also set the remote I/O bits (numbers of
ports using input/output: I/O parameters 14 and 15) as a multiple of 16.
