M7.3 Network Control System
The M7.3 network control system was developed for the administration of medium to complex network configurations with up to 320 network participants. Every participant is connected via a bus module to the network and can be configured for a specific task. This guarantees the maximum flexibility for the set up of customized material handling systems.
- M7.3 touch-screen – The high-resolution touch-screen simplifies user control, as well as the adjustment of process parameters and allows the user a comprehensive view of all attached units.
- Line server LS-B30T – Provides for the control of up to 31 freely configurable bus modules, which can be connected in parallel to one CAN-Bus line. All functions which are available for the respective bus modules can be managed and controlled from the line server. A complete system can have up to 8 individual CAN-Bus lines.
- Bus module BM-4/4 – Provides individual control of vacuum loaders, blower stations, central filters, dry air valves, purging valves, etc. Any function can be assigned to the 4 digital inputs and outputs of the bus modules and therefore, gives the system virtually unlimited possibilities of configurability for each particular application.
Networked Drying System
The M7.3 control system permits the connection of DRYMAX battery dryers with network cards to the central M7.3 control system. This allows the visualization of internal parameters and conditions on the generously dimensioned M7.3 control screen as well as the entry of temperature values for the various connected drying hoppers.
Coded Material Source Licence and Lot Management
Choosing the wrong material for a drying hopper in the course of a material change procedure is not only leading to weak drying results, but can also have fatal consequences for the production of parts. To minimize this risk, and after having activated a licence, the M7.3 network control can monitor this process. For the clearance of the conveying process, the operator has to define the material change at the control device, and afterwards to confirm the material source and the suction lance via barcode scan. If this is done correctly, the charging process starts. If not, an error message is displayed, and the conveying process (with the wrong material) is not executed. This function can even be extended applying the WiMaTRACE batch monitoring function.
Connection to ERP Systems
All relevant control data and parameters can be transferred to a company wide enterprise resource planning (ERP) and process data monitoring (PDM) system via the open standard protocol OPC. For the connection to a PDM system the M7.3 control system is optionally equipped with an OPC Interface Licence, which enables the communication between an external computer and the control system. A customer supplied OPC client accepts the required data from the M8 control system and manipulates it internally. The data exchange happens via the Ethernet interface.
