Hi Giel, the event counter channel is typically limited in the "Increasing" and "Decreasing" columns when using the Object list method. Similar limits can be used in the Qcode method.
As an example:
In the increasing column:
A: Button 1 Press (Single object)
C: A and B
This would limit the event counter channel from increasing above a value of 10
Adding to Mark's comments, there is information in the XS2 instruction book regarding using a switch in parallel with an IQAN module. If you look in the section discussing the Digital Outputs there is a diagram showing the basics of the setup.
I am working on an application that requires a dynamic gage. There is an adjustable temperature that has a color coded temperature range. When the temperature is changed, the color coding does not match the range. I now have to create a separate gauge for each temperature selection and show and hide appropriately. It would be very nice to have adjustable min/max values in the gauge.
The COUT channels are PWM, current regulated channels, so they will not control a device that requires 4-20 mA since they are of the PWM signal type. The current is regulated, meaning that the output will detect changes in the load and adjust accordingly to compensate for the changes. Also, the output from a COUT is not consistent below the rated minimum for a COUT which is typically around 100 mA. It may not hit the commanded value below the rated minimum mA. The minimum is listed in appendix A of the instruction book for a particular module.
The Peak USB to CAN adapter was added in IQANdesign 4.06. 12.
I am not sure exactly what you are trying to do, but if it is adding an image over the display page that is done by just adding an image to the display page. Depending on the order of the items added to the page, it will overlay the later added items over items previously placed on the display page.
Using several master modules in an application is not an issue, but there are a few things to keep in mind.
1. CAN bus load on the CAN buses used for inter master communication as is with any CAN bus with multiple modules. You don't want to have CAN traffic at a level that will overload the bus, also keeping in mind CAN bus loads can spike from time to time depending on several factors.
2. There is one master considered the "Head Master" and will have the address of 0. Only one master can use the address of 0.
3. The workload of handling system logic can be distributed as desired, i.e. on one master or multiple masters.
Humidity can enter the MD3, but it should not affect the operation. There is a breather port on the back of the MD3 to allow moisture to escape if it enters.
Hi Jon, One way is to open the project file in IQANdesign 5. I would recommend making a copy first, just in case you do not like the results. The copy will give you a file to fall back on. Once opened in IQANdesign 5, then you would add the MD4-7 module and drag the items under the "Application Logic" on the MD3 over to the MD4-7. You will need to set up any CAN bus links under "System layout." I would suggest setting up the MD4-7 display pages also so you can view the MD3 pages for comparison. Once that is complete, then you can delete the MD3 module from the project file. Make sure you get everything you desire that is associated with the MD3 before deleting since everything will be deleted that is linked to the MD3.
