Software Gemnis Studio 12

serie Gemnis

The software for programming the modules of the Gemnis series is available in the new Gemnis Studio version 12 which has a fully updated graphic layout and new programming functionality.
The Gemnis Studio software is a graphic development environment for the creation, simulation and debugging of programs designed for uploading to Gemnis line modules.
Gemnis series safety modules can implement safety circuits with a safety category of up to SIL 3 according to EN 62061, PLe and category 4 according to EN ISO 138491.

    New interface

    The new Gemnis Studio 12 programming software has a completely new look. With retractable side panels housing the sensors and function blocks, the field available for working in the programme is now larger and neater. Among the new settings available is the option of choosing between light and dark display themes:

    Another innovation is the advanced menu, which groups the sensors according to electrical type so as to guide the programmer in choosing the correct sensor for the project.

    New function blocks

    Gemnis Studio 12 includes new function blocks for performing mathematical functions that are very useful for applications with frequency inputs for speed control or with current inputs for analogue sensors. The new function blocks are:

    • SUM performs addition of the input data and a second value
    • ADIFF calculates the absolute difference between the input data and a second value
    • AVG calculates the arithmetic mean of two values
    • MUL performs the mathematical function of multiplying two values
    • WTOB converts data in Word format into a value in Byte format
    • BTST allows verification of the value of a given bit within the input data

    PNP safety outputs

    The electronic safety outputs of the Gemnis modules are always protected and monitored for dangerous faults. In order to perform this monitoring, test impulses (i.e. very short switch-offs of the outputs) are created in the safety outputs while the outputs are active. These test impulses are generally undetectable on passive loads (contactors or similar); in rare cases, however, they can disturb the inputs of digital devices such as PLCs or electronic drives.

    With Gemnis Studio 12, it will be possible to disable the test impulses of the PNP safety outputs in cases where the application requires it. Faults such as short-circuits to the external positive pole are still detectable when the outputs are switched off.

    Remote support

    The new remote support management, which is included in the new software, will allow you to receive help from Pizzato technical support directly from the Gemnis Studio software window with just a few clicks.

  • FeaturesFeatures


    Gemnis series modules can manage all of the following safety device types:

    • Mechanical safety switches
    • Switches with solenoid for guard interlock
    • Magnetic safety sensors
    • Optical safety barriers
    • Safety sensors

    The modules are also equipped with features that allow you to perform:

    • Safety timers
    • Detection of various types of faults in safety devices or their connections
    • Verification of the module’s internal temperature limit values
    • Mathematical functions (Gemnis Studio 12)

    Finally, Gemnis series modules can:

    • Manage four or eight electronic safety outputs, or up to four relay safety outputs
    • Manage various signalling outputs (not safety-related)
    • Status information and data settings via the integrated USB communication port.


    Gemnis Studio 12 - Programming

    The Gemnis Studio program is a graphic development environment for the creation, simulation and debugging of programs that are uploaded to the corresponding modules of the Gemnis family.

    The Gemnis Studio software has been designed with the objective of making Gemnis series module operation as immediate and visual as possible. With this aim, we decided to create a work environment – the Desktop – where, as far as possible, the user can amass all the information required to actually “view" and not just "imagine" the behaviour of the project under development.

    This is the reason we have made room for graphical object representations, of the physical characteristics of the module in use, and immediate interaction, by means of simulation, with the created program.

    The desktop is the main user work area, the zone where the flow and processing to be applied to the data detected by the module are defined using the graphical program interface.


    Gemnis Studio 12 - Simulation

    Gemnis Studio is equipped with a useful simulation environment, which allows you to run tests on your program under development and check its correct operation before you install the program in a module.

    Upon start of the simulation phase, the desktop and the way you interact with it change. During this phase you can simulate module operation by interacting with the sensors and simulating real world conditions or operations.


    Gemnis Studio 12 - Monitor

    You can monitor operation of one or more Gemnis modules in real time using the Monitor function.

    You can observe the overall operation state of the module and various data relating to the program being executed, including a list of most recently saved programs.

    The execution status of the program as well as the status of the module inputs and outputs can be viewed in real time. In Gemnis Studio 12 the video data update has been made faster and for the analysis of large projects, graphical pan & zoom functions are also available in the Monitor.

    SERIAL function block

    Gemnis Studio 12 - SERIAL function block

    The SERIAL function block allows "X" type information (bits) to be exported from the Gemnis module to an external device (a PLC, for example).

    There are two communication options (synchronous and asynchronous) to choose from, and you can customise various communication parameters such as the number of bits to be transmitted, the speed with which to transmit them and the IDLE status of the channel when the transmission does not occur.
    The number of bits to be transmitted can be set between a minimum of 2 and a maximum of 32, and the maximum communication speed is 100 bits per second using synchronous transmission.
