The digital modules from FORSIS - IO CONNECT MINI and BASE

The project of the digital modules for machine data acquisition was launched at FORSIS because a large number of customers were looking for a solution that offers the possibility of acquiring and controlling the signals in a control cabinet or on a machine. This is how the digital modules of the IO CONNECT series were developed.

The decentralized distribution of the machine data acquisition modules is playing an increasingly important role. The focus is on reducing the number of input stations for machine and work groups. But the possibility of direct mounting of the terminal on the data sink, which reduces the cabling effort, also makes the modules attractive. The flexibility and the modular structure when combining terminals for machine data acquisition complete the range of digital modules from FORSIS.

The digital DIN rail modules IO CONNECT from FORSIS are designed for direct TCP / IP network connection (Ethernet) and can therefore be integrated directly into your existing company network. Optional parallel or direct communication via USB is possible with the modules of the IO CONNECT BASE and IO CONNECT LCD series, which enables use on mobile workstations. The modules offer a variety of communication and acquisition options that implement direct machine connection. Depending on requirements, RS232, RS422, RS485 and a number of digital inputs with different functions can cover the machine data acquisition (MDE).

Control of actuators or control of individual machine parts is also possible. This can be the activation of the machine by the production manager, or automatic feedback of the machine status via a signal light. The possibilities are limitless here.

In addition to the existing range, FORSIS GmbH also offers accessories and assistance with the dimensioning and integration of your project. Contact us!

Connection diagram for machine data acquisition: MINI

Maschinen Datenerfassung Anschlussplan MINI

The inputs and outputs of the IO CONNECT MINI and the supply voltage are galvanically isolated from each other.
The inputs can be connected to a machine and the outputs to a PLC without having to establish equipotential bonding.
Only the supply voltage and the interfaces are brought together for technical reasons.

As with the IO CONNECT MINI, the inputs and outputs of the IO CONNECT BASE are potential-free with respect to the interfaces and the supply voltage.
The possible extensions are again implemented potential-free with respect to all other interfaces and inputs and outputs.

The digital module IO CONNECT LCD offers additional modules for interaction with the user. For example, messages can be output via the software or scrolling displays for statistical information can be displayed.

We would be happy to inform you personally about other functions if required.

Extension module for machine data acquisition: 16xIN

Maschinen Datenerfassung Detail 4x Relais

The expansion module 16xIN for the IO CONNECT BASE and the IO CONNECT LCD expands the basic modules with the following functions:

  • 16 electrically isolated digital inputs with LED display

These functions are fully integrated into the familiar programming, no further adjustments are necessary.

Extension module for machine data acquisition: 4xRELAIS

Maschinen Datenerfassung Detail 4x Relais

The extension module 4xRELAIS for the IO CONNECT BASE and the IO CONNECT LCD extends the basic modules with the following functions:

  • Four galvanically isolated changeover relays with LED display

The relays are changeover relays of the type "G2RL-2-DC5" from Omron. These can be connected completely potential-free by the user. The switching contacts of the relays have no electrical connection to other parts of the IO CONNECT. The extension is recognized directly in the firmware of the IO CONNECT Main and included in the firmware version. The extended relays (outputs 09-12) are programmed and configured just like the other outputs of the IO CONNECT. All functions of the outputs are identical to those of the other outputs of the IO CONNECT. When programming, the user must ensure that both the number of switching cycles and the switching frequency are limited.


Extension module for machine data acquisition: 8xIN 8xOUT

Maschinen Datenerfassung Detail 8x IN-OUT

The expansion module 8xIN 8xOUT for the IO CONNECT BASE and the IO CONNECT LCD expands the basic modules with the following functions:

  • Eight electrically isolated digital inputs with LED display
  • Eight galvanically isolated digital outputs with LED display

These functions are fully integrated into the familiar programming, no further adjustments are necessary.

The digital inputs of the digital modules of the IO CONNECT series BASE, MINI and LCD are high-active and connected to a common ground. If a voltage is applied to an input, the status is recognized as high (input set). Otherwise the state is recognized as low (input open / on ground). All inputs and their common ground are potential-free in relation to the supply voltage and the interfaces of the IOC module.

The digital outputs of the modules are high-active and connected to a common ground and a common supply voltage. If an output is set, the supply voltage of the IOC is switched through. Otherwise the output is left open.

All input and output states can be queried at any time via TCP / IP or USB. The maximum input frequency and the switching times of the outputs are 100 Hz, which defines a minimum pulse duration of 5 ms.

With the pulse generator it is possible to generate a single pulse or a time-limited / unlimited pulse width modulation (PWM) in the digital module. Each output can be programmed with a pulse generator independently of the others. The polarity of the impulses depends on the starting state of the output. If the output is low, a pulse is high. If the starting state of the pulse generator at the output is high, the pulse is low. The pulse generator settings are not saved. Pulse generators can be overwritten at any time.

With the digital modules of the IO CONNECT BASE, MINI and LCD, debouncing of the rising and falling edge can be programmed for each input. The debouncing times can be configured independently for both edges and for each input in 1 ms steps from 0 ms to 65535 ms.

The functions of the time switches of the digital modules are also very extensive. The user has the option of defining up to 32 timers. These can be set very precisely with the year, month, day, hour, minute and second.

With the help of the time switches, outputs can be switched on or off or toggled at defined times. The programmed settings are fixed in the EEPROM so that they still have an effect after a restart.

The digital inputs of the digital modules can record and evaluate pulses in the millisecond range. Different functions for counting the impulses in freely selectable time units can be activated independently for each input (steps in seconds, 32 bits).

The recording of the total number of pulses and counting with start and stop conditions can also be activated independently for each input. When recognizing pulses, you can set whether to react to a falling or a rising edge. If only the current state of the digital inputs is concerned, this can also be called up at any time. With the counters, a distinction is made between a CONSTANT counter and six other configurable counters, which can be configured independently at each input.

The CONSTANT counter is saved in the real-time clock at least once per second and is available again after a restart. The six configurable counters have no memory function and are only available during runtime. These must be reprogrammed after a restart.

Counter types:

Counter 0: CONSTANT counter
Counter 1: TIME counter counts until a point in time is reached - individually
Counter 2: TIME counter periodically
Counter 3: IMPULSE counter counts until a value is reached - individually
Counter 4: IMPULS counter periodically
Counter 5: manual (single)
Counter 6: manual (periodic)

These functional options are very helpful, for example, to invert signals from the digital inputs and output them to the digital outputs. Or to drive signals from the digital modules and apply them to multiple outputs.

Furthermore, the states of outputs can be changed with rising or falling edges. A total of up to 32 "input = output" functions can be programmed. The programmed settings are fixed in the EEPROM so that they still have an effect after a restart. The delay time for this conversion is only in the range of a few milliseconds, but can also be set independently for each pin and for both edges (debouncing).
