Charm EZ Reader

Charm EZ Reader – Inhibitor Screening Test.

In order to control production and manage raw materials well, analytical data is very important. Processes need to be closely aligned to provide the most efficient and best production procedures. This includes permissions and rights management. The Inhibitor Screening Test by Charm is an intelligent testing and screening device that is network-ready. Conducted analyses can be received by the device and also passed on to other systems.

Achieve More with Combined Systems

If an analytical screening device like the Charm EZ Reade, which is used for inhibitor screening tests, is not interconnected – and thus part of the production plant, all analytical work has to be copied from the device onto paper and then entered into another system manually. This is time-consuming and error-prone. The OPC Router ensures that test results become available in a connected-systems environment and that data management becomes totally automated. Once this is the case, no one has to wait for test results and everyone can be sure that the inoramtion provided is correct. The whole process is now much safer and faster.

Industry 4.0 via Charm

Connecting screening devices that test liquids or other material for possible contaminations – among many other analytical testing scenarios – makes it perfectly clear why analtical testing devices need to be interconnected to other systems in a laboratory or production plant, providing the quality of Industry 4.0 connectability. Instead of dealing with manual data entry and data distribution on paper with double or triple data entry scenarios, data is exchanged automatically. Other systems can receive and pass back data through the interface technology provided by the OPC Router.

About the OPC Router

The OPC Router offers a visual network configuration interface for successful cross-linking of your systems. A high variety of plug-ins turns the OPC Router into a powerful data hub for industrial applications.

Easy configuration, sophisticated monitoring and robustness are main distinguishing features of the OPC Router.

Combining Systems

That’s how easy it is.

Transfer Objects

The Transfer Object of the Charm plug-in makes fields with analytical results available.


Every analysis has multiple specified fields that can be selected as data fields. The most important ones are Result (level of stress), SampleID (sample number), Interpretation (i.e. whether positive or negative), LotNumber (batch), as well as many more.

Trigger Functions

The Charm plug-in has three Triggers that become active when messages are received.


When the Charm reader sends data, a transfer is triggered. The analytical data is made available in data fields.


In order to monitor and control devices, a heartbeat can be received. The heartbeat can be set up as trigger: As soon as a heartbeat occurs, a trigger becomes active that prompts a transfer. This can be used to document the online status of a device or to prompt an error message alert, for instance.


If errors are detected, a trigger becomes active. This makes it possible to target errors specifically in order to solve problems quickly.


The Charm plug-in makes all fields of the respective device type available  that the manufacturer offers. These fields are made available as data fields.

How do Transfer Objects, Triggers and Browsing work?

The OPC Router establishes connections between systems that address core functions of the OPC Router.

Functions of the respective plug-ins may vary, due to the different nature of each connected system.

Transfer Objects

Sources and Destinations

Transfer objects are the sources and destinations inside the OPC Router. They contain data fields with read and write functions. Depending on the respective interconnected system, the possible configuration scope of sources and destinations may vary.

Homegeinity on the Outside – Heterogeinity on the Inside

Inside the OPC Router configuration, the transfer object abstracts the respective system of any connected system into a simple data input and data output block. Thus, the functions can be treated in the same way although each connected system has very individual features.

Trigger Functions

Prompting Connections

Triggers determine execution time of data connections. Various triggers can be used for these connections, independent of transfer object type. Within each connection, several triggers can be used together via AND/OR-connections. Triggers can also be useful as data sources if the prompting event is combined with data reception.


Searching and Finding Data Fields

Easy browsing also makes data field configuration easy when establishing transfer objects in order to establish the respective interface connection. The browsing mechanisms may vary, depending on the system and its available plug-in.

Reading out Structures

Many plug-ins that are available for the OPC Router offer easy search and selection tools for quick identification of respective data fields without the need for specific knowledge about inherent subsystems. The user can easily browse through the data. Data source structures may vary according to the specification of each respective plug-in.
