Configuration chart
Communication functions of FP7 CPU Unit
• The FP7 CPU Unit can open a virtual communication line with an Ethernet-supporting device
connected to LAN, and send/receive data.
• IP address of the FP7 CPU unit, protocol (TCP/UDP), connection method with devices, port
numbers, etc. should be specified in the configuration menu of the programming tool FPWIN
GR7.
• In master communication commands SEND/RECV, messages in accordance with the
protocol are automatically generated by PLC. In the user program, reading and writing can
be done simply by specifying the station no. and memory address and executing commands.
• Communication functions can be selected depending on the partner device to be connected.
