16 Port Modbus TCP/IP module

Characteristics

A Modbus I/O module consists of 8 inputs and 8 outputs which can be mapped onto Modbus registers, holding registers, or coils through the Automation Control Application. Inputs and outputs may be defined as data type digital, numeric, or hex.

Communications

A 16-Port MODBUS module supports TCP/IP communications with a MODBUS TCP protocol.

Addressing

Addresses for 16-port Modbus TCP/IP modules are in the following format:

<IP Address>:<Port>:<Poll Rate>:<Client ID>

Where:

• IP Address: 4-ocet V4 IP address of the Modbus device

• Port: Modbus port number (0 – 65535)

• Poll Rate: Polling time value for TCP communications with the Modbus device (1 – 9999 sec.). The recommended poll rate is 5 seconds.

• Client ID: Optional device ID which may be required depending on vendor. Defaults to zero if not specified.

Examples:

• 192.168.1.200:565:20

• 10.10.30.44:1017:20
