Modbus TCP Server
When the SmartAXIS is configured as the Modbus TCP server, Modbus TCP client devices can read/write data to the SmartAXIS.
When the SmartAXIS receives a valid request from a Modbus TCP client device, the data is read or written according to the request
received. The communication data received from Modbus TCP clients is processed at the END processing of the user program.
Modbus TCP Server Specifications
Address Map
Modbus TCP client can access the Modbus devices (Coil, Input Relay, Input Register, and Holding Register) of Modbus server to
read or write the device data (I, Q, M, R, T, C, and D) of SmartAXIS. Refer to the following table to configure the Modbus TCP
clients.
*1: These 4-digit addresses are used in the communication frame. To calculate the address used in communication frame, extract lower 5 digits of
the Modbus address, subtract 1 from the value, and convert the result into hexadecimal. For details, see “Modbus Slave Communication” on
page 11-8.
*2: Access within the device range for the SmartAXIS type used.
