I am very unhappy with the inability to import function groups from working IQAN2 code into IQAN4. Atlas Copco has spent multiple man year developing and testing their IQAN2 control applications. I want to be able to take advantage of this as we work towards updating their next gen rig to work under IQAN4. I know I could do this if I was coding in MatLab/SimuLink, C, or C++. I have tried exporting the function groups with references, and without, and all I ever get when I try to import them is the following:

I am aware that the connections to the function group are going to be broken, and will need to be connected appropriately. I should not have to track these down and re-specify/reconnect these, in IQAN2 though, especially when I'm importing the function group from one type of module (MC2) to another (MC3).

By taking this approach IQAN makes code re-use almost impossible. I'm very disappointed

Please fix it.

Some Ideas I have had,

1) It would be nice to justify a comment box to the right. It comes in handy when you want the text to be right next to that function.

2) Error Value for a 2 bit value. It defaults to False, but it would be nice to be able to put (-1). That way in the program I an tell there is an error and do some other code with it.

3) TSC1 SA - Integer Parameter. I saw a post a year ago about adding this to IQAN 4, but it has not been done yet. I was wondering if you knew when I could expect that.

What happens if the application running on the MC3 crashes? Does the safety ASIC reacts and brings all of the outputs to a safe state (unpowered)? Thanks!

I saw this in the release notes:

Since equipping some of the machines with IQAN4 software, we've had some weird errors coming up during the start-up of the software, or outgoing ports going 'red' and not functioning until rebooting the modules seperately using the emergency stop. We've had this with XC10 modules and a XA2 module.

My guess is that it has to do with the boot-time of the modules in combination with the initialization of the CANbus.

Could this solve/improve this issue?

With the new Iqan 4.03.27, the qcode window now re-formats all my code if I try to add some code in it. I never had this issue with 4.02.

Example, I had a functional code, and went to add a variable at the top of the qcode, and it did this.

Has anyone had the need to communicate with Industrial PLC's? The Ethernet port would be the best way to do it if the MD4 could support Ethernet communications with the PLC. It is expensive to incorporate a CAN to Ethernet converter and also it adds another piece of hardware in teh system that you need to mount and support. Is there any plans to add Ethernet communication protocol to the MD4 (other than camera and PC communications?)

Along the same line, has anyone created an EDS document for the IQAN MD3 or MD4 that can be used to set up communications with the Alan Bradley PLC over CAN?

It is possible to use tha same Bus Can for two different CAN systéme .

J1939 an Expansion on the BUS CAN C on the MD3

When I look the project check, I don't have error.

Is there a way to show only preferences (or other category of main menu) by pushing menu (or custom made) button?

Hello,

I like to use the application default value, 'max current', of a COUT in a math channel. Is this possible? I don't want to use integer parameters because you loose the standard adjustable menu of the COUT channel.

Kind regards,

Robin

Hello,

Is there any way to add more digits as 4 to the pincode
