Software Gemnis Studio

CS MP programmed multifunction modules - Gemnis series



The programmable multifunction safety modules from the Gemnis series have been updated to version 11, with the introduction of new functions and better performance in terms of hardware and software. This update remarkably widens the range of application for these products. Gemnis series safety modules are able to create safety circuits classified up to SIL 3 according to EN 62061, up to PL e and category 4 according to EN ISO 13849-1.The Gemnis Studio program is a graphic development environment for the creation, simulation and debug of programs suitable to be entered in the modules belonging to the Gemnis line.

Window for the validation of the project

The new version simplifies the procedure for compilating, validating and sending the programme to the module. The project toolbar buttons have been reduced from three to two. The first one is to be used for compilation only, while the second one opens the window for validating and sending the programme. 
The window above shows the results of the evaluation and allows the user to send the programme to the module. The results of the compilation are shown in the logs that are displayed in the top area. The compilation of the programme can lead to positive or negative results, on the basis of possible configuration errors. Incorrect compilation prevents the user from sending the programme to the module, until the reported problems are solved.

The new programme analysis window consists of:

  • Top area containing the results of the programme evaluation
  • Central area for entering information for validating of the project
  • Bottom area for sending the programme to the module.  This area will be visible only whether a module is connected to the computer and the project is compilable.


EDM function block
The EDM function (External Device Monitoring) allows the user to check the integrity of the external devices through direct control of their state. The external devices are typically relays or contactors with guided contacts and equipped with at least a normally closed contact, that achieve the EDM circuit. If one of the external devices is broken, the EDM detects the fault by comparing the XEdm and XIn entries.




New validation report

In the new version of Gemnis Studio a new report can be displayed and printed. 
The validation report summarises the information of the entire project, namely:

  • General information about the project
  • Functional safety parameters
  • Information about the sensors used
  • Formal evaluation
  • Front image of the module
  • Information about terminals

The Gemnis series modules are able to manage all the following types of safety devices:• Mechanical safety switches 
• Switches with solenoid for locking the guard 
• Magnetic safety switches 
• Optical safety barriers or optical safety sensors (in category 4) 
• Safety sensors 
• Mushroom pushbuttons for emergency stops 
• Rope switches for emergency stops 
• Safety mats or sensitive bumpers with 4-wire technology 
• Bimanual controls in category IIIA or IIIC 
• Safety selectors 
• Enabling devices. 
• 4-20mA Analogic sensors (Gemnis Studio 11) 
• 0-4KHz Frequency signals (Gemnis Studio 11) 
• Systems with 2-beam crossed muting (Gemnis Studio 11)

Moreover, these modules are provided with functions also allowing the following operations: 
• Safety timing 
• Detection of numerous types of faults in safety devices or their connections 
• Checking of temperature limits inside the module 
• Status communication by means of bus ports. 

Finally, the Gemnis series modules can: 
• Manage up to four different safety outputs, either electronic or with relay 
• Manage various signalling outputs (not safe) 
• Carry out status communications and data setting by means of the integrated USB communication port or appropriate communication boards.     



The Gemnis Studio program is a graphic development environment for the creation, simulation and debug of programs suitable to be entered in the modules belonging to the Gemnis line. 

The Gemnis Studio software has been designed with the objective of making the operation of a Gemnis series module as immediate and visible as possible. 
The choice was made to create a work environment – the Desktop – where, as far as possible, the user can get all the information necessary to actually "see" and not just "imagine" the behaviour of the project being developed. 

This is the reason for trying to make room for graphic representations of the objects, physical characteristics of the module used, and immediate interaction, by means of simulation, with the program created. 

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 by means of the graphic program interface.


The Gemnis Studio software is provided with a simulation environment useful for running trials on the Application Program which is being created, and checking its correct operation before installing it onto a module.

The initiation of the simulation phase transforms the desktop and any possible interaction with it. During this phase, it is possible to simulate module operation by interacting with the sensors and simulating conditions and operations as in the real world. 


The operation of one or more Gemnis modules can be monitored in real time by means of the Monitor function. 

The user can view the general functioning of the module and various data about the program being executed, including the list of the last programs stored. It is now possible to view in real time the program execution status, as well as the inputs and outputs of the module. In Gemnis Studio 11, the update of data on screen is faster and the Monitor includes pan & zoom graphic features for the analysis of large projects
