KA-LOGO!-IO-Simulator

Description

KA-LOGO!-IO-Simulator kit helps to simulate logical states on the Siemens LOGO! 8 logical controler. With the IO simulator board, You can simulate each bits on the LOGO! inputs using toggle switches. It is possible to use the embedded LOGO! ADC's to measure a voltage, ALS or temperature values.

Included LED module can signalise states of four LOGO! outputs. Integrated LED drivers (NCR401U by Nexperia) provides constant brightness of the indicators.

The kit is especially recommended for Automation Engineers and persons, who wants to learn and tests their codes without connecting every used sensors.

Attention! The product is designed for the Siemens 6ED1052-1MD00-0BA8 and 6ED1052-1MD08-0BA0 logic controllers. In case of using the product with other Siemens Logo! 8 controller, please ensure it's compatibility.

Code Description
KA-LOGO!-IO-Simulator
  • Assembled and tested module of IO simulator
  • Assembled and tested module of LED indicators
  • Two spacer sleeves
  • Two screws for spacer sleeves
Terminal blocks (for supply)

The IO simulator module has four terminal blocks. Connectors marked as "L+" and "M" are used to connecting and forwarding the power supply between modules. Double terminal blocks on the left side allows for:

  • [upper] - connect a power supply to the module and the LOGO! 8 device
  • [lower] - forward supply for the IO indicators module

Simulator's board switches

The IO simulator module is equipped with toggle switches marked as INP: I1-I8, , which sets the digital states on each lines of the LOGO! 8 module. Selectors INP: I7, I8 can be used to connect the analog signals to LOGO! 8 ADC's. Using two switches "SEL", You can configure the signal character on the I7/I8 lines (by connecting to supply voltages for bit simulation or by connecting to a analog lines). Slide switches allows to configure the analog inputs. Line Al1 might be connected to ALS sensor (LIGHT) or potentiometer (POT). For the Al2 line You can select readings from temperature sensor (TEMP) or external analog input (EXTIN).

Switch Position Description
I1...I8 0 Low logic level on the I1...I8 lines
1 High logic level on the I1...I8 lines
SEL [I7/Al1] I7 I7 switch sets the logical states
Al1 The I7 voltage depends on the analog value from ALS sensor or potentiometer
SEL [I8/Al2] I8 I8 switch sets the logical states
Al2 The I8 voltage depends on the analog value from temperature sensor or the EXTIN input
LIGHT/POT LIGHT Analog voltage measures from the ALS sensor
POT Analog voltage measures from the potentiometer slide.
TEMP/EXTIN TEMP Analog voltage measures from the temperature sensor
EXTIN Analog voltage measures from the EXTIN input
Potentiometer

The potentiometer on the IO simulator board could be connected to the I7 line. Voltage of the potentiometer slide has range from 0 to 10 Volts DC.

Ambient Light Sensor

The ALS sensor of the IO Simulation board could be connected to the I7 line of LOGO! 8. Output voltage of the photoresitor has range from 0 to 10 Volts DC (depending on ambient light level).

Temperature sensor

On the IO Simulator module the voltage matching circut is applied for temperature sensor MCP9700. It scales the temperature sensor output voltage to the ADC range of LOGO! 8 device. On the line I8, it is possible to obtain 0 to 10 V DC range (with 12-20mV margin from 10V line) for temperatures measured from +5 to +105 Centigrade degrees.

External sensor connector (EXTIN)

It is possible to connect a external sensor to the IO Simulator module. Output voltage of connected sensor must not be higher than 5V DC. 5V power supply for the external sensor is available on terminal block, located at right side. For example, the compatible external sensor is Pololu - 2474. Connection method is shown on the image:

Spacer sleeves

Included spacer sleeves needs to be mounted to the IO Simulator module for preventing a tensions of board (and the excessive exploitation of LOGO! 8 terminal blocks). The mountage method is shown on the foto:
