a program that translates the hardware communication protocol used by a PLC into the OPC protocol
. The OPC client software is a program that connects to the hardware, such as an HMI. The OPC client communicates with the OPC server to receive data or send commands to the hardware.
Why is OPC needed?
An OPC server
reduces the load on data source devices
as it enables communication with several applications, while having only one connection with the data source. This reduces multi-access from the data source, and hence reduces the load on the data source.
What is the difference between OPC UA and OPC DA?

What is an OPC item?
OPC Items are
the backbone of a group
. They get their values from PLCs and the values are then used by other items in the group and/or to write to the database. They are directly subscribed to an OPC server at the rate of the group and are executed by the group so their alarms are evaluated when the group is executed.

What ports does OPC use?
When an OPC client connects to an OPC server, it connects to
port 135
(the RPC port mapper), which assigns one TCP port and one UDP port to the component. Communication between client and server is directed to those ports.
