6. BOOTP operation within the module must be DISABLED. To DISABLE BOOTP operation
the following explicit message must be sent to the module:
Service Class Instance Attribute Data
0x10 0x64 0x01 0x6E 0x00
7. Cycle power to the module. Once power is re-applied the module will come online with the
new IP address and Subnet mask. BOOTP operation should be disabled at this point so no
BOOTP requests will be issued by the module.
8. A network ping should be used to verify that the IP address and Subnet mask have been set
correctly.
The control unit must always be configured with Modbus®/RTU RS-485 network address set to 1.
Input (T->O) Assembly Object (Class 0x04, Instance 0x65)
The following is a mapping of I/O values for the standard Ethernet/IP® assembly object instance
0x65. These are values that are sent from the Ethernet/IP® server (control unit) to the Ethernet/IP
client (typically a PLC). The input assembly size is 13 (16 bit words).
Data Types
Bool – 1 bit Boolean discrete data
Usint – 16 bit unsigned integer analog data
Sint – 16 bit signed analog data
Float – 32 bit signed floating point analog data
Floating point values are represented in IEEE format (32-bit) where the 1 st register is the LOW
word and the 2 nd register is the HIGH word.
