C-WS-0001R

C-WS-0001R is an indoor touch wall controller. It contains a light intensity sensor, a universal AI input for connecting other temperature sensors (e.g. floor temperature, outdoor temperature). Alternatively, it is equipped with a display, temperature, humidity, air quality sensor, RFID reader and 2-8 buttons.

Variant HW configuration

The module number defines its HW configuration, e.g. C-WS-0001R.x1.6SHN. Automatic loading of the module configuration is only supported for PLC Foxtrot 2, alternatively it can be set manually in the configuration dialog.

List of available module variants and their basic parameters: catalog.tecomat.cz/produkt/c-ws-0001r

Keyboard

The module is controlled using capacitive buttons, where short and long presses are detected. The long press delay is adjustable in the module configuration, as well as the sound response to the press. The buttons are illuminated either collectively by white LEDs, or separately by point LEDs for each button separately (red and green).

Display

The graphic display can be adjusted using the DISPLAY.MODE parameter. Up to two numerical values (DISPLAY.VALUE1 and DISPLAY.VALUE2), their data type (DISPLAY.VALUE1_UNIT and DISPLAY.VALUE2_UNIT) and one separate icon (DISPLAY.ICONS) or separate text (DISPLAY.TEXT) can be displayed.

Configuration

The module is configured in the I/O Configurator tool. The activation of the individual devices of the module is carried out by ticking the appropriate checkbox of the device.

Automatic detection of a specific variant assignment of the module is only supported for the Tecomat Foxtrot 2 PLC series. In other cases, the module assignment variants can be set manually in the I/O Configurator, see following picture.

Sound response to press

Option to turn on the sound response to the button press.

 

Long press delay

For buttons, the module directly evaluates short and long presses on individual inputs. By entering a value, you can set a time delay after which activation of the DI binary input will be signaled as a long press (PRESS). Activation of a binary input shorter than this specified value will be signaled as a short press (CLICK). The delay value (T_press) is entered in the range of 0.1÷2.5s.

Types of AI input

For temperature sensors, the value is transmitted in °C (with a resolution of 0.1°C), for the general resistance range of 100kΩ in kΩ (with a resolution of 10Ω) and for the voltage range in mV.

Input type	Measuring range
Pt1000, W100 1,385	-90 ~ 320°C
Pt1000, W100 1,391	-90 ~ 320°C
Ni1000, W100 1,617	-60 ~ 200°C
Ni1000, W100 1,500	-60 ~ 200°C
NTC 12k	-40 ~ 125°C
KTY 81-121	-55 ~ 125°C
0V100k	0 - 100kΩ
0 - 2V	0 - 2V

Tab. 1 Parameters of analog inputs

 

AI input filtering, temperature filtering

By entering a non-zero value of the time constant, the 1st order digital filter is activated. The filter is given by the relation

y_t = (y_{t - 1}·τ + x)/(τ + 1)

• x - the current value of the analog input
• y_t - output
• y_{t - 1} - last output
• τ - time constant of the 1st order filter

The value of the filtering time constant is entered in the range 1÷254 and represents a time constant in the range 1s÷254s (the value 255 is intended for service purposes).

Temperature offset

Correction offset of the internal thermometer, by which the measured temperature of the internal thermometer will be adjusted.

 

The structure of the transmitted data

The module contains a total of 6 devices. Individual devices are included in the structure of the transmitted data, which is visible from the I/O Settings panel in the Mosaic environment.
