Manual EzOPC

What is the purpose of EzOPC?

EzOPC is an OPC server which provides two data links: • To an “EasyPort EA module Baugruppe” from Festo Didactic • To a “STEP 7 Simulator” from Siemens PLCSIM5.1 or higher. The data can be written and read by any OPC 2x-compliant OPC client.

What is OPC?

OPC stands for open connectivity via openstandards and is an established standard interface in the field of automation technology. It ensures an efficient flow of data between Windows applications and automation devices. OPC defines interfaces and interoperability between applications and communication systems from different manufacturers. This enables tasks such as visualisation, measurement data acquisition or control functions to becarried out irrespective of the makes of equipment involved. OPC is thus an open standard which is not tied to any specific application.
