During data logging, the FP‑I4C unit collects and saves the data from all connected devices. The log files can then be downloaded or transmitted to a server.
This sample application is the basic configuration of a PLC-based monitoring and control system that collects and evaluates process data. In the figure, an FP0R PLC and four power meters of the Panasonic Eco-POWER METER series are connected to the FP‑I4C unit. The measurement values from temperature sensors connected to the PLC will be logged in the FP‑I4C unit. The energy consumption values supplied by the power meters will also be logged and can be transmitted to the PLC using the script function. Logging is performed at a fixed time interval set in the FP‑I4C unit.
Configuration
The FP‑I4C unit has the fixed IP address 192.168.0.1. It is connected to the Ethernet devices via a network switch. The PC must be on the same subnet as the FP‑I4C unit.
The KW2M power meters have the IP addresses 192.168.0.70 and 192.168.0.71.
The KW9M power meters have the station numbers 1 and 2 and are connected via RS485 (19200 baud, odd parity, MEWTOCOL-COM protocol).
The FP0R PLC is connected to the FP‑I4C unit with its TOOL port (115200 baud, odd parity, MEWTOCOL-COM protocol).
