MOVI-C^® CONTROLLER as a simple OPC UA server

The following figure shows an example implementation of a visualization (client) to a MOVI‑C^® CONTROLLER (server) using OPC UA.

The HMI panel acts as the interface to the system/machine operator. Behind the user interface there is usually extensive code with corresponding programming effort that should not be lost by using a MOVI-C^® CONTROLLER. In case of a replacement, this code can be retained as long as the HMI panel has an OPC UA client. This significantly reduces the effort required to change from any controller to a MOVI‑C^® CONTROLLER.

When using the MOVIKIT^® OPC UA software module, you do not need to insert variables in a fieldbus telegram to transfer them to a higher-level controller and then send them to the visualization. Symbolic access is easy to handle, as is the architecture through a direct connection between the MOVI‑C^® CONTROLLER and the visualization.

The MOVIKIT^® OPC-UA software module provides access to all sensor and actuator data provided in the IEC part of the MOVI‑C^® CONTROLLER. This allows numerous products that use the OPC UA standard to communicate with each other.
