Modbus TCP Communication via Ethernet Communication

The FC6A Series MicroSmart supports Modbus TCP clients and Modbus TCP servers. Connect the Ethernet port 1 on the FC6A
Series MicroSmart to enable the FC6A Series MicroSmart to communicate with Modbus TCP compliant devices.
When configured as a Modbus TCP client, the FC6A Series MicroSmart can monitor and change the data memory of the network
devices supporting Modbus TCP server. A maximum of eight connections can be allocated to Modbus TCP clients. Each connection
can communicate with one Modbus TCP server device.
When the FC6A Series MicroSmart is configured as a Modbus TCP server, the device data of the FC6A Series MicroSmart can be
monitored and changed from Modbus TCP client devices. The FC6A Series MicroSmart can allocate a maximum of eight
connections for Modbus TCP servers.
For the Modbus TCP client function and how to configure it, see "Modbus TCP Client" on page 6-19. For the Modbus TCP server
function and how to configure it, see "Modbus TCP Server" on page 6-24.
