Software

Our software solutions have been optimized for fast and target-oriented implementation and easy access in case of service. We have developed specific service concepts for programmable logic controller (PLC) of our machines, our SCADA system (PrepMaster Core/ Entry) and our laboratory information system (PrepMaster Analytics). In this way, we guarantee trouble-free operation of your system and assist you with your daily maintenance tasks.

Programmable logic controller

HERZOG offers machines with programmable logic controllers (PLC) from various suppliers such as Siemens, Allan Bradley, Schneider Electric and others. Already when programming the machines we pay attention to a high degree of standardization of the PLC program and drive control. This leads to a substantial simplification during commissioning and in possible later service cases. Furthermore, it makes it easier to adapt the machine sequences to the technical requirements of our customers.
We regularly equip plants and larger machines with a service router for the duration of the warranty. This allows our software department to quickly and easily connect to the machine control system for error analysis or modification without the need of an on-site visit. The router can be either temporarily linked via the customer network or, if this is not possible, via a mobile phone network.

SCADA system PrepMaster Core and PrepMaster Entry

The PrepMaster Core/ Entry software undergoes continuous development since 25 years. The software design with its machine-oriented programming ensures absolute availability and real time- control of the system. To further improve standardization, all PrepMaster projects are configured using the PrepMaster IDE (Integrated Development Environment). The PrepMaster IDE guarantees that only up-to-date and tested configuration and driver files are used. In addition, the programmer has access to a large library of routing procedures that ensure an optimal process flow. The graphical user interface makes it particularly easy to obtain an overview of the processes in the plant, even during subsequent service calls. In addition, automatic error checking and correction by the PrepMaster IDE already takes place during configuration and programming.
PrepMaster provides various tools for system analysis. This allows processes in the system to be reproduced exactly and possible errors to be evaluated. Using standard remote maintenance software such as TeamViewer, our specialists can connect to the PrepMaster software after consulting with you.

PrepMaster Analytics

Our laboratory information system PrepMaster Analytics includes numerous functions for monitoring the proper operation of your automation as well as tools for service and process optimization. With our modules for tool condition monitoring (TCM) and predictive maintenance (PM), you can monitor, e.g., the condition of your milling machine, pulverizer or pneumatic cylinders. Functions for evaluating the system performance assist you with optimizing the processes in your system. The display of warning and error messages along with machine and video data makes error analysis much easier.
In addition, PrepMaster Analytics optionally includes its own maintenance module that supports you in maintaining and managing your machine and instrument inventory, enables you to create and monitor maintenance tasks and provides a statistical evaluation of your maintenance effort. Furthermore, manuals and spare parts lists can be stored in electronic form.

Contamination tests

The automation of processes such as fine grinding, dosing and pelletizing of sample material requires an efficient and autonomous cleaning of the components used.
Depending on the requirements and methods involved, HERZOG offers various solutions, such as dry cleaning with compressed air, wet cleaning, sand and granulate cleaning as well as the use of blank samples. In order to minimize potential carry-over, material-specific test series can be run in advance using XRF analysis. This enables the cleaning parameters to be set precisely and exactly adapted to the customer's needs. This means that contamination can be avoided during routine operation.

Influence of parameterization

When preparing an analytical sample, there are a number of factors that can influence the quality of the measurement result. Particle size effects, matrix effects, preferred orientation of particles, the roughness of the sample surface as well as the shape of fused beads are only a few phenomena that have to be considered.
The following parameters, among others, play an important role:

  • Grinding duration and vessel
  • Addition of grinding aid and binding agents
  • Pelletizing pressure and hold time
  • Fusion time
  • Swiveling of the fusion crucible
  • Choice of fluxes and additives

HERZOG offers the possibility of assessing these parameters and optimizing them for the respective customer requirements.

Homogeneity tests

Since only a limited portion of the sample interacts with the X-rays during the analysis, it is essential for XRF and XRD that a representative, effective sample surface is available. Under certain circumstances, pelletizing sample material into metal rings can lead to undesirable segregation or introduction of particles potentially influencing analysis results. In order to avoid possible heterogeneities in fused beads or pressed pellets, HERZOG employs various preparation methods.

Optimization of automation processes

Laboratory automation is intended to achieve the optimum operating conditions that ensure a high sample throughput with stable analytical quality. When planning laboratory automation, we not only rely on our decades of expertise in the field of sample preparation, but also use additional planning tools such as simulation programs.
Before delivery, the automation procedures are tested extensively in our factory. Among other things, we use analytical methods such as spectroscopy and particle size measurement to exactly align the respective machine parameters and achieve the optimum result for each application. It goes without saying that we work closely with our customers to achieve this goal.
