3.5.8 Subnet Mask (for Ethernet communication)
[Procedure]
(1) To set the subnet mask, write data to the four D registers in the table below. The data
type is integer.
(2) After writing that value, write 1 to the Ethernet writing status register, D0294.

Initial value of subnet mask: 255.255.255.0
NOTE
• A subnet mask value can be set for the PR300 with Ethernet communication function.
• Subnet mask settings are only effective when the protocol is set to Modbus/TCP.
[Example]
To set the subnet mask to 255. 255. 255. 0:
For station number 01, use PC link communication (without checksum) and the random
