The Vision 290 uses VisiLogic software, which is different than U90. U90 is only for the M91 and Jazz series controllers. You will need to download VisiLogic 9.5.0 from our downloads page. Then you will be able to use the Vision 290. It does not have built in I/O so you will need to use one of the snap in or expansion modules that has temperature inputs. The logic that you use will be much the same as you saw in U90, setting them in the hardware and using compare function blocks to set the output.

Hello Nick, Have you tried to update the OS? In VisiLogic under the Connections tab click on Communicaion and OS. Go to the fourth tab which is Install Operating System and click Check. This will check your current OS and prompt you to install a new one if it is outdated. Which sample application were you trying to load? Another question is can you access info mode when the display stopped working? To do this hold your finger on the screen for seven or so second into the Info Mode screen comes up. You can then click Enter Info Mode and the default password is 1111. Are you able to access Info Mode? Alex

Hello, In the hardware configuration of U90 select the model you are using that is capable of using temperature measurement. The M91 and Jazz each have three models. In the hardware configuration select the appropriate Analog Input capable of temperature measurement and select the type from the drop down menu. Then select an MI operand to link the value for the temperature. You can select either Celsius or Farenheight in the mode drop down menu. I have written a simple example program that selects the analog input MI and compares it to a constant value. Using the comparison function blocks you can set the output to run. Another comparison block resets the output allowing the program to shut the output off at a value lower than the conditions that enabled it to run. http://forum.unitronics.com/files/file/31-%7B%3F%7D/ I would also recommend watching the Unitronics Webinar on the Jazz which describes how to create a basic program and goes over the software features.

Hello, You can use a bit or any set of conditons to access the different alarms screens using a function block. Within VisiLogic click on the drop down menu Utils/ Alarms/ Show Alarms function block. The show alarms function block can show Alarms in group, Alarms Details, or Alarms history depending on which you wish to view. Once you access the Alarms screen, you can easily access the others. I have also linked a useful PDF that one of our Moderators created to help view alarm screens. http://forum.unitronics.com/index.php?app=core&module=attach&section=attach&attach_id=516

Petar, This is absolutely possible. You could create a HMI screen to display the current status of events, as well as log historic information to a data table. Does it need to be an alarms display or just a status log? Does it need to be viewed via the PLC or stored? All information could be stored to SD cards if a historical log is necessary. If you do not need to use the Alarms utilities I would recommend watching the Data Tables webinar which would allow you to configure custom tables with a real time clock, the status of outputs, inputs, strings, and system operands. http://www.unitronics.com/Content.aspx?page=datatables - Alex

Petar, It is possible to create a custom HMI configured to display alarms, but that would involve extra programming. There is already a pending alarms, alarms in group, alarm details, and historical alarms display built into the VisiLogic software. What kind of customization were you looking to create? - Alex
