The SchoOPC-server is a modular and scalable server application for connection over OPC (Open Connectivity). Supported standards:

  • OPC DA 1.0a,
  • OPC DA 2.05,
  • OPC DA  3.0,
  • OPC AE 1.0,
  • OPC AE 1.1 (limitations see below).
  • OPC UA 1.02

The process connection is realised through special device drivers, of which a couple is available as a demo-version or as a free version that´s included in the standard installation.

We develop OPC-servers for our clients. 

You need an OPC-server for your devices or applications, contact us and we prepare an offer about the devopment of your OPC-server.

OPC HDA is OPC-standard for alarms (Alarm & Events) or data archiving (Historical Data Access).
OPC HDA is rarely requested, because most HMIs or SCADAS (see WinErs) already have similar possibilities and only few OPC HDA-clients are available.
