ipConvLite/MEC2PBM is a universal protocol converter developed for the conversion of standard protocols to the PROFIBUS DP, Master protocol. Based on ipConvLite, ipConvLite/MEC2PBM basically offers the same functionalities. Compared with ipConv, its function range is limited to the most widely used standard protocols, thus allowing a lower price.
ipConvLite/MEC2PBM is available together with the hardware platform MEC2 PROFIBUS.
We offer a complete package of software and services covering the following:
Please go to Use Cases ipConvLite/MEC2PBM for some practical examples.
System configuration is completely executed in a web browser. No other special configuration tools are required, a normal notebook with a network interface card and web browser are all that is needed.
ipConv in its current version 4 enables encrypted communication between web server and browser via the HTTPS protocol.
The main menu provides access to all relevant functions of ipConv, showing the overall system status at a glance.
The following functions are available:
The following example shows the configuration of a protocol stack (here IEC 60870-5-101, Master). All parameters are shown with their configured values, relevant measurement units, and short descriptions.
A parameter value can be changed by clicking on the parameter name. A detailed description is also shown, if available. The entered value is checked for the permissible value range, or a selection list offers a pre-selection of permissible values.
Only relevant parameters are displayed, for instance, if the link layer type is set to "unbalanced", only the corresponding parameters are shown.
ipConv enables fast and efficient processing of large volumes of data points by allowing data import from tables. These tables are based on templates and may be processed with various spreadsheet programs, such as Microsoft Excel. The extended use of formulae minimizes the data volume, substantially reducing the number of errors.
With protocol converters it is essential that the state of all interfaces can be determined at a glance. This is all the more important, if the available personnel at the facility does not have particular knowledge of the system.
The diagnostic data can be accessed with the DIAGNOSTICS button in the main menu. The most important information is provided subdivided and in plain text with time stamps. Colored highlights indicate whether a state is OK or not.
You can configure the type of information, descriptions and colors.
Plain messages, measured values, and also control commands, such as a button for initiating a general poll, can be shown.
With all communication applications, it is always essential to know which data is transmitted via the protocol and how the data is converted from one protocol to another. And it is even more important when problems occur with transmission. ipConv features logging and archiving functions for all data traffic.
ipConv allows you to keep track of the system state and information flow inside the converter by recording and archiving all information passing through a module for a given time period. This data can be recorded:
The range of data recorded is defined by the logging level. This can be changed dynamically (at runtime) or statically (in the configuration) for each module.
The logging level defines the representation format for the sent or received information. Data can be represented either in hexadecimal code or in decoded, symbolic form or both. This example shows the content of a logfile generated from an IEC 60870-5-101, Master protocol stack.
Data is stored directly in the easy to read ASCII format. Logfiles can be displayed, searched, or downloaded for offline diagnosis via the web interface.
All recorded data is archived cyclically, enabling you to keep track of communication over a period of days or even weeks (depending on the data volume).

ipConv is capable of representing and simulating all signals in a simple project-specific form, a functionality which is particularly useful for signal tests during commissioning. This greatly facilitates tracking down wiring and configuration errors.
All data points can be shown in a hierarchical form defined by the configuration. Names, nesting depth and signal range can be freely chosen and configured for each project. This enables personnel not familiar with ipConv or the relevant protocol to access information.
The signal name, information type, value, quality identifier and time stamp (if available) are shown.
At the same time, data and commands can be simulated directly in the web browser. This functionality is very useful, if only one communication partner is connected (control station or RTU). Pretests can thus eliminate most configuration errors, even if the complete communication path is not yet available.
To meet even increased security requirements, ipConvLite is fully capable of redundancy in combination with a second device.
With redundant protocol converters, reliability can be ensured, based on the "hot standby" principle. At any one time only one device assumes the active role, while the passive device monitors the active one and takes the initiative if it fails.
This minimizes downtime due to maintenance work or component and interface outages, for example.
The redundancy coupling can be realized via Ethernet as well as over serial connections. If separate serial communication connections must be connected to both redundant devices, the CS channel switch will be applied.
