The initial situation: connection of the ERP system only up to sensor level
corratec relies on an electric overhead conveyor and the Microsoft Dynamics AX ERP system in their production facility. The ERP system connects all departments in the company. That includes, for example, the warehouse, which connects to the system with the help of scanners. However, this connection only extends to the sensor level of corratec production. As a result, the electric overhead conveyor with a Siemens S5 controller could not connect to the ERP system.
Additionally, corratec sensed the need to modernise the visualisation of errors and downtimes of machines. Until now, the visualisation functioned with simple light signals. Since a few years, visualisation has been added to the production, which shows the plant image and errors on a clear dashboard.
The goal: modernisation with the OPC Router
With the goal of modernisation, the corratec production manager, Mr Sagberger, began searching for suitable software that could modernise production in a simple and uncomplicated way. It was significant to Mr Sagberger that the software is capable of pointing out production errors in order to prevent downtimes and production stops. During his search, he found that the OPC Router fulfilled these requirements without any problems. In addition, the OPC Router convinced Mr Sagberger with the very simple connection of business management data and production data, which means that the software more than meets the requirements of the production manager.
The OPC Router was first used about two years ago. The existing Siemens S5 control system was connected to the OPC Router via an IBH interface. That resulted in the first visualisation, which showed plant data and ERP data. corratec switched to a Siemens S7 control system in production about a year later. On the one side, this changeover meant a higher amount of data. On the other side, the OPC Router offered some new features for modernisation of the data transfer. That was an opportunity to restructure the data transfers and the visualisation. That was done with the help of the inray support team and in very close cooperation with corratec, so that the changeover was optimally designed for Mr Sagberger and all requirements could be implemented in a customer-oriented manner.
“The OPC Router is the heart between the database and the ERP system.”
