There are three options to program a Mini-PLC.
In any case the software is free-of-charge.

• Basic programming knowledge -> miCon-L
• Basic C programming knowledge -> Arduino
• C programming experience -> KEIL MDK

Also visit our Downloadcenter to find a variety of programming samples and templates for the BARTH® Mini-PLCs.

The intuitive graphical Programming Suite miCon-L opens up a variety of options for both beginners and professional users achieving the shortes possible time-to-market for your project.
The miCon-L forum provides all information you need to get fast and easily in touch with this outstanding software tool which is preinstalled on all BARTH® Mini-PLCs.

Yes, it is possible to directly connect an unipolar Stepper Motor (e.g. RS Art. No. 191-8299) to a STG-8xx Mini-PLC. Simply write your program in miCon-L, C-Code or within the Arduino IDE to get full control of the stepper motor. So you get an easy an cheap solution for small Motion & Control Applications. A set of free demo programs are available in our Downloadcenter area (STG-850).

Each STG-8xx Mini-PLC features a serial TTL-232 Port (3.3V). This port allows usage as classical RS-232 interface when C Programming is used. You only need a hub to change TTL to RS-232 voltage level. Using the miCon-L Software Suite the serial interface is reserved for software communication only.

Several of our customers use a Mini-PLC in combination with LabView. It is very easy to integrate your Mini-PLC within LabView using the CAN communication interface. Simply use a CAN/USB adapter to interface the Mini-PLC to your PC. The CAN protocol should contain the parameters and values to be shared with the LabView software.

Add one CAN bus termination resistor of 120Ω at each end of your CAN bus.
Only the CAN Display DMA-20 and Parameter Programmer PG-65 include a termination 1k resistor which is intended for laboratory use only without correct CAN bus topology.
Take care to use a line structure for your CAN wiring and avoid nodes using higher speeds.

1 Mbit/s -> 25 m
800 kbit/s -> 50 m
500 kbit/s -> 100 m
250 kbit/s -> 250 m
125 kbit/s -> 500 m
50 kbit/s -> 1000 m

There are four options to mount or fasten a Mini-PLC.
The related products can be found here.
You can fasten the Mini-PLC:

• With DIN Rail Kit HA-30
• With DIN Rail Bracket HA-18
• With two M4 screws
• With cable ties (3.6mm)

The Mini-PLC models supporting IrDA provide a reliable wireless infrared interface reading out and setting user-defined parameter from a Mini-PLC. The Parameter Programmer PG-65 is the tool of choice to communicate with the IrDA Mini-PLC models.

The following connector type is used:
Manufacturer: Phoenix Contact
Type: COMBICON FMC1.5
Pitch: 3.5mm

Depending on the type of Mini-PLC the connectors are green or black colored.

The PIC18® based Mini-PLCs use green connectors. All ARM® Cortex® Models use black connectors. Connector type and pitch are always the same.

Due to a small positive leakage current an output without any load will let you measure a voltage. A slight load to ground (e.g. 1mA) will cause a zero voltage at any low-stated output.

The STG-600´s USB interface is connected as followed (from left to right):

1 = +5VDC
2 = D+
3 = D-
4 = GND
