a maximum (function MAX), of the function output of the relevant control blocks. After we have
assigned the inputs and outputs, we can change other configuration fields of the control block if the
default values do not suit us, and in the end we will again write the block configuration in the
controller with the “Write” button.
Note
: All outputs can be actuated by two states (ON/OFF) or in the PWM mode. In the case of the external
Ext1 and Ext2 outputs this actuation will cause fast PWM at the output with the carrier frequency of 200
Hz, in the case of other outputs slow PWM with the carrier frequency of 0.002 Hz (it corresponds to the
period of 500 s). The manner of actuation depends on the configuration of the individual control blocks.
After the configuration of the control blocks, we can change the general options in the “Settings” tab,
for example connection with the WATTrouter, low tariff signal source, setting of the outside
temperature, etc. We will again write these changes in the controller with the “Write” button.
In the “Statistics” tab it is possible to change the loading period of the online chart and to select values
which should be monitored. We will again write these changes in the controller with the “Write”
button.
Save the configuration on the computer disk with the “Save” button. It can be loaded again by means
of the “Open” button. Due to the security restrictions of browsers, saving is usually allowed only in the
folder designated for downloading (“Downloaded items”, etc.).
DESCRIPTION OF WEB INTERFACE ITEMS
This chapter describes all items of the controller web interface in which all values and states of inputs, outputs
and other operational values are shown clearly and the states and settings of the control blocks are shown in
the individual tabs.
The web interface is implemented by means of the AJAX/XML technology, Javascript must therefore be allowed
in the web browser.
Authorization of the data write in the controller is not performed by means of the common cookies standard
but by sending access data directly in the data of every request for data writing. This mechanism simplifies the
implementation in a superior whole, where work with cookies could be problematic.
MEASURED QUANTITIES AND STATES
Digital temperature inputs:
T1-8 – input designation.
Name field – it shows an input caption and makes it possible to enter this caption. The text can have a
maximum of 16 characters in the ASCII code.
Status indicator – green light if the sensor is connected and working.
Value – it shows the measured temperature in tenths of °C.
Analog temperature inputs:
T9-11 – input designation.
Name field – it shows an input caption and makes it possible to enter this caption. The text can have a
maximum of 16 characters in the ASCII code.
Status indicator – green light if the sensor is connected and working.
Value – it shows the measured temperature in tenths of °C.
