The server provides “two-sided” connectivity: one side provides access to applications that support OPC DA; the other side provides access to FP Series PLCs.
In order to enable the user to perform functional tests, a simulation mode is implemented. This mode allows you to design the application without any PLC being connected to the computer.
The server complies to the following OPC DA client/server technologies:
OPC DA 1.0a
OPC DA 2.05a
OPC DA 3.0
Data can be exchanged between client and server in asynchronous, synchronous and refresh mode.
A standardized interface allows you to:
Monitor data from Panasonic FP PLCs
Synchronize data access and data writing
Use various communication types
PLCs can be accessed via serial port and Ethernet. The server offers modem support to connect to remote stations via dial-up phone calls.
Specify the communication mode at the communication channel level when you configure the application. Setting up the communication channel to use the modem means that dialing and connecting to the remote device is fully transparent to the OPC client application. Modem connections and direct serial communication work similarly.
