Dematic SAP Subdrivers are an innovative approach designed to eliminate basic logistic problems caused by so-called "Middleware" or subordinate systems by directly communicating the SAP systems with the Programmable Logic Controllers (PLCs).
Classic automated warehouse and conveyor installations are controlled by PLCs which execute transport orders that are sent by the subordinate system via interfaces. The subordinate system controls the bin location management, the stock of materials and the orders, and also the storage and retrieval strategies and the management of instruction deliveries to the PLCs.
The simplest solution to establish a direct connection from PLCs to the SAP applications is to integrate a component which receives the PLC's messages and translates them to SAP orders (and vice versa). Possible existing programs in the PLC remain untouched.
The Dematic subdrivers supersede the use of Middleware and the implementation of additional SAP components. The Dematic Subdriver component is mounted within minutes and connected to the existing network.
