In the previous article we presented a concept and features of the MultiCon series devices and the outline of their possibilities obtained as a result of well developed software and a modular design. This part will describe other advantages, including simple operation and configuration using a TFT with a touch screen, a thing well know from such devices as smartphones or tablets.
Easy change of data presentation and displayed channels is a feature which might be useful in many cases. MultiCon offers numerous possibilities in this area – the basic function is bringing up the contextual menu by touching the display briefly. Then, a set of buttons appears on the bottom of the screen to switch between the display modes, channel groups or to enter the menu.
The “MODE” buttons allow a quick selection of data presentation method on the screen. Depending on whether we need a detailed information on the signal value, quick insight into the signal level, or parameter trend over time, the data can be presented.
In the first four modes, the panels present in a clear manner the name and the unit of measure which are specified and entered by the user, its graphical or numerical representation, and in addition a percent value in relation to a set level. The last mode allows to present as numbers up to 30 channels on one screen. This mode is particularly comfortable in MultiCon-141 equipped with a large 5.7” display.
The time graph data presentation mode is useful for recording operation. Depending on the configuration, the graph background can be black and the graph itself can be set as horizontal or vertical to maintain conformity with traditional paper recorders. The user can also set the line thickness. For the sake of clarity of results, the measurement channels are assigned to groups. The “GROUP” buttons are used to select the group which will be displayed. A mimic board view with 30 channels from groups from 1 to 5. Using the “GROUP” buttons will change the range of displayed channels; this also applies to all other data display modes.
MultiCon CMC-99 has 10 groups, and MultiCon CMC-141 has 15. A single group can contain maximum 6 channels, but the channel assignment to groups is not restricted, and the same channel can be displayed in many groups, providing the user with full flexibility to group various indications (e.g. one room, the same equipment, groups of measurements of the same type, etc.). Selecting the number of channels assigned to a group, we can obtain different sizes of various indicators.
The MultiCon series device equipped with the ACM (advanced communications module) allow also a very easy remote monitoring of measurement results usinf a web browser, as well as a very attractive graphical presentation in the form of built-in or user-created websites. Along witht he device, the manufacturer supplies a set of built-in Java applets which using the modbus TCP protocol provide the programmers with an easy mechanism to retrieve data from the device, as well as ready-to-use formats of data presentation on the computer screen.
In order to facilitate the use of their own websites by the users who do not know HTML, we have prepared a few standard examples which are distributed with the free DAQ manager software used to manage the data recorded.
It is necessary to mention one more data display mode – “Setpoint” – although it is more related to the channel operation mode than the presentation of the results. Touching the screen in the field of such configured channel, the user can in no time at all change a fixed value assigned to the channel (e.g. a threashold in the controller). In addition, this mode can be mixed with binary data presentation as described above which allows an easy definition of function keys on the screen. The other interesting feature of the “Setpoint” mode is access to the settings. Depending on the needs, the admin can configure a channel so that the changes are made only by authorised users or any operator, also the one who does not know the password.
As a piece of interesting information, let us here present a “trick”. A quick access to group settings or settings of channels in a group. Instead of entering the menu and selecting the channel from the list, you can just touch and hold the screen in the area of the channel that interests you and you immediately enter the editing of this channels parameters. Operation of the group is similar: press and hold the top bar on the group name and you enter the relevant submenu.
