Each OEM configures their IQAN systems to meet the needs of the machine. The message on the display would be something Alamo set up, so you would need to check with them or possibly in a user manual to see what would trigger the message. It is not a message that is generated by an IQAN system by default.
We are working on expansion versions of the MC4x module. They should be available in the not to distant future. They will be XC4x modules.
Generally speaking, the issue is that the Vref is at 0.0 VDC. You need to determine what is causing this. As Ed mentioned, a short to ground or something connected to the Vref causing the drop to 0.0 VDC. Since your sensors are working it may be a momentary drop, just long enough to trigger the error, but recovers shortly after. I would recommend connecting an oscilloscope to the Vref to see how it performs when the error is generated. That may give insight to the issue.
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.
