■ D8284, D8285: Communication Mode Information (HMI Connection) (HMI Connection 1 to 8)
D8284: Indicates the communication mode of HMI connections 1 through 4.
D8285: Indicates the communication mode of HMI connections 5 through 8.
The allocation of connections in the device (bit assignment) is as follows.
• Client connection (most significant bit = 0)
0000: Unused
• Server connection (most significant bit = 1)
1000: Maintenance Communication
■ D8304 to D8307: CPU Module IP Address (Write-only)
These registers are used to write the CPU module's IP address.
IP address: To set as aaa.bbb.ccc.ddd, write the following.
D8304=aaa, D8305=bbb, D8306=ccc, D8307=ddd
■ D8308 to D8311: CPU Module Subnet Mask (Write-only)
These registers are used to write the CPU module's subnet mask.
Subnet mask: For aaa.bbb.ccc.ddd, write the following.
D8308=aaa, D8309=bbb, D8310=ccc, D8311=ddd
■ D8312 to D8315: CPU Module Default Gateway (Write-only)
These registers are used to write the CPU module's default gateway.
Default gateway: For aaa.bbb.ccc.ddd, write the following.
D8312=aaa, D8313=bbb, D8314=ccc, D8315=ddd
■ D8316 to D8319: CPU Module Preferred DNS Server (Write-only)
These registers are used to write the CPU module's preferred DNS server.
Preferred DNS server: For aaa.bbb.ccc.ddd, write the following.
D8316=aaa, D8317=bbb, D8318=ccc, D8319=ddd
■ D8320 to D8323: CPU Module Alternate DNS Server (Write-only)
These registers are used to write the CPU module's alternate DNS server.
Alternate DNS server: For aaa.bbb.ccc.ddd, write the following.
D8320=aaa, D8321=bbb, D8322=ccc, D8323=ddd
