4.4 Programming with miCon-L
Without learning a difcult programming language the
BARTH®Mini-PLC can be easily programmed using sim-
ple and vivid graphical function blocks. This block design
meets graphical standards of the latest graphical program-
ming languages.
The miCon-L software suite features programming, simula-
tion and test in one unique software design tool. The exible
programming option offers a variety of possibilities in indus-
trial, automotive and maritime applications.
Programming the STG-115 follows using the USB port of
your PC with installed miCon-L software suite.
miCon-L also supports full simulation and visualisation ope-
ration modes.
The software provides a variety of visualisation blocks and
interactive elements to control and debug the Mini-PLC.
For detailed information please read the BARTH®miCon-L
manual and the BARTH® Application Notes on:
www.barth-elektronik.de
4.5 Delivery content
• BARTH®Mini-PLC STG-115
• Spring terminal connectors (for supply, input, output)
5 INSTALLATION
5.1 Mounting
The STG-115 must be installed and wired
by a trained technician who knows and
complies with both the universally appli-
cable engineering rules and the regulati-
ons and standards that apply in specic
cases.
The STG-115 is intended for panel mount using four M4
screws to x the PLC.
Before mounting create a cut-out for the Mini-PLC with the
dimensions 68 x 92 mm.
To x the PLC place four holes diameter 4.5 mm with the
distances 100 x 80 mm.
To ensure the IP65 protection grade of the
front panel an additional sealing is man-
datory. The sealing has to be applied bet-
ween the front panel and the housing.
The 3M type 5915 is suitable for most
applications.
Please verify the sealing for your applica-
tion! Otherwise the degree of protection
may be insufcient!
Take care to meet the environmental con-
ditions of the STG-115.
After creating the cut-out, place the Mini-PLC properly and
x it using four M4 screws.
Only use M4 cylinder head type screws
fastening the Mini-PLC, applying a maxi-
mum torque of 0.5 Nm !
Otherwise damage of the front panel may
occur !

5.3.2 Connecting the inputs
You can connect sensors, switches or buttons to the inputs.
The sensors may be temperature, ow, pressure, photo-
electric sensors or proximity switches, for example.
The STG-115 is well suitable for any sensor featuring a vol-
tage or current loop output, 0 to 10 VDC or 4 to 20 mA, for
example.
Common features of the inputs IN1-IN10 (X6, X7)
• IN1 to IN8 are selectable analog/digital inputs
• IN9 and IN10 are switchable inputs 0-10VDC or 4-20mA
• Wide input voltage range 0 to 32VDC
• Comprehensive integrated protection circuits
• Outstanding electromagnetic compatibility (EMC)
• Electrostatic discharge protection (ESD)
Due to the pull-down resistors integrated in the STG-115,
any switch (NO/NC) can simply be connected between the
positive supply (+VDD) of the STG-115 and the desired input.
The voltage at any input must not exceed
32VDC referred to ground (GND).
Higher voltages or reverse voltage lower
than -32VDC may cause irreversible
damage of the Mini-PLC!
At both IN9 and IN10 the applied signal
must not exceed 12VDC or 25mA!
The 8-pole X6 connector named ‚IN1‘ to ‚IN8‘ contains all
common 0-30VDC inputs of the Mini-PLC.
The 2-pole X7 connector contains two special inputs named
‚IN9‘ and ‚IN10‘ which are DIP-switchable from 0-10VDC to
4-20mA. The default value of both inputs is 4-20mA.
To change the input IN9 from 4-20mA to 0-10V please set
the switch 1 of the S1 DIP switch from ON to OFF.
To change the input IN10 from 4-20mA to 0-10V please set
the switch 2 of the S1 DIP switch from ON to OFF.
Switches 3 and 4 of S1 are not related to any function.
Using the inputs IN9 and IN10 as current loop 4-20mA type
a pull-down resistor of 470 Ohm is used within the STG-115
to receive a voltage from a current signal.
Using the miCon-L software suite you have to know wether
or not the inputs IN9 and IN10 are congured as current
loop type to recalculate the current from the received vol-
tage value within miCon-L.
5.2 Wiring
5.3 Overview
Connectors
X1: Power supply (fused)
X2: USB connection (PC interface for miCon-L)
X4: Common output ports OUT1-OUT8
X5: Relay output OUT9
X6: Common input ports IN1-IN8
X7: Special input ports IN9-IN10 (0-10V/4-20mA)
X8: Common ground (bridged parallel)
S1: DIP switch to congure X7 ports IN9 and IN10
5.3.1 Connecting the power supply
The STG-115 features an outstanding wide supply voltage
range from 16 to 32 VDC at lowest current consumption.
So the Mini-PLC can be integrated within battery sup-
plied 24V DC systems (cars, trucks, battery powered cars,
forklifts and digger, for example).
Turn off the power supply before perfor-
ming any wiring operations!
False electrical connection, voltage
reversal or disregarding the electrical
specications may cause irreversible
damage of the Mini-PLC!
Connect the supply voltage of 16 to 32 VDC to the X1 termi-
nal named ‚+VDD‘ and ‚GND‘ of the STG-115.
Wire the positive supply to the ‚+VDD‘ marked terminal. The
negative (ground) will be wired to the ‚GND‘ terminal.
All connectors are carried out as plugable spring terminal
connectors for a wire gauge of 0.25 to 1.5mm².
Ensure correct power supply voltage
range and polarisation! External fusing of
8A max. is mandatory!
Disregard may cause irreversible damage
of the Mini-PLC!

5.3.3 Connecting the outputs
Depending on load type and current the STG-115 is able
to directly drive electric loads without any additional driver
or protection circuit. The Mini-PLC provides 8 digital solid-
state highside outputs and one isolated relay output.
Common features of outputs OUT1 to OUT8 (X6)
• Rugged solid-state higside switch up to 1.5A
• Paralleling permissible up to 6A
• Short circuit protection and current limitation
• Fast demagnetization of inductive loads
• Stable behaviour at undervoltage
• Comprehensive integrated protection circuits
• Outstanding electromagnetic compatibility (EMC)
• Electrostatic discharge protection (ESD)
Features of output OUT9 (X5)
• Relay NO/NC changeover output type 1A/30VDC
• Electrically isolated
• Outstanding electromagnetic compatibility (EMC)
• Electrostatic discharge protection (ESD)
The 9-pole connector X4 named ‚OUT1‘ to ‚OUT8‘ contains
all digital outputs of the Mini-PLC. While OUT1 to OUT8 are
overload-protected highside switches, OUT9 (X5) is carried
out as electrically isolated relay changeover NO/NC switch.
A logical HIGH within miConL will switch the Mini-PLS´s
supply voltage at OUT1 to OUT8, while the isolated contact
of OUT9 changes over (NC/NO-NO/NC).
Aviod a current exceeding 1A/30VDC at OUT9 because this
outputs is not protected against short-circuiting or overload
current !
The total current sourced by OUT1 to
OUT8 must not exceed 6A!
Avoid reverse voltage at any output higher
than the Mini-PLC´s supply voltage!
OUT9 provides NO short circuit protection.
Take care the contact current not exceeds
1A! Negligence may cause irreversible
damage of the Mini-PLC!
6 OPERATION AND PROGRAMMING
To operate the STG-115 rst establish proper power supply
connection at both +VDD and GND terminals.
For programming and PC connection the connection cable
VK-12 (Art. No. 0091-0012) and a PC with installed Windows
operating system are mandatory.
Before you connect the Mini-PLC to the PC you have to ins-
tall the USB-/COM-port driver (folder ‚USBdriver‘) from the
software download package:
www.barth-elektronik.de/download/9045-0008-A.zip
Now install the miConL software suite from the ‚miCon-L‘
folder. Follow the setup instructions of miConL. Afterwards
establish the PC connection using the VK-12 connection
cable and run miConL.
For choosing the correct COM-Port please click the right
button (congure serial interface) located on the main menu
page and conrm the added COM-Port used by the STG-
115.
Now start miConL with creating a new project (Project->
New) or open a miCon-L sample application (Project-
>Open).
