“Default tab” – select a tab which should be displayed after the loading of the web interface.
“Search for digital temperature sensors” – it starts the function of determining the digital sensors
connected on the bus. If all connected sensors are not shown after this function has been run, make
sure that the data bus is connected properly and check the shielding. Frequent errors in
communication with sensors especially occur in the case of longer distances and incorrect shielding.
The function is protected against unauthorized access by means of authorization.
“Change username and password” – tick this field if you want to change your username and password.
Enter the new username and password in the boxes which will appear after you have ticked this
option. As this change is also subject to the configuration write, it is necessary that you know your old
username and password. If you do not remember them and you therefore cannot write the
configuration, use the HC downloader software and recover access to the controller via the USB
interface.
STATISTICS TAB
This tab shows:
a)
A fully configurable online chart which makes it possible to monitor temperature curves in real
time, etc.
b)
Daily, weekly, monthly and yearly statistics of selected parameters of the control blocks.
Note:
This function is available only with the activated SW extension Statistics.
ONLINE CHART
In this line chart it is possible to select up to 5 rows which can show temperature progress or states of digital
inputs and outputs. It is possible to choose the period of loading values in the chart in the range from 1 s to 10
minutes. The maximum number of points on the time axis of the chart is 144 (if a ten-minute period is selected,
this corresponds to 1 day). This chart is not saved in the non-volatile EEPROM memory and therefore after
reset or a power failure of the controller the data will be erased. The data will also be erased after every
change of the configuration of this chart.
Description of the configuration and status elements:
Period – it states the period of loading values in the chart.
Row 1-5 – drop-down menus configure the input or output which should be read in the relevant chart
row.
DAY
It shows daily statistics on the current day or optionally for at least seven days back. The option is specified in
the relevant drop-down list. The selected data from the main control blocks are shown.
Description of the types of shown values:
Temperature type item – it shows the minimum and maximum temperature on the given day and the
arithmetic mean for the relevant day. The data is only read if the temperature is valid.
Power type item – it shows the minimum and maximum power (of the pump, etc.) and the arithmetic
mean for the relevant day. In order to provide more objective information the data is only read if the
device power is not zero.
Counter type item – it shows the counter signalling the time of switching on or activity of the given
device for the relevant day.
