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 .

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

I am using a MD3 with the cycle time set to 10ms under the Main Group.

The cycle time needs to be that low because it is important for the IQAN system to be as responsive as possible for the machine it is being used in and prevent a malfuntion. As time has progressed the IQAN program has evolved the utilization rate has continued to climb.

Is it possible to have a multi-threaded program, or maybe multiple main groups? I'm thinking 1 main group with all the critical functions with a cycle time of 10ms and a seperate group with a higher cycle time of say 50ms.

I am making use of function groups and disabling them as needed but I was hoping for a better solution esp. for the critical time sensitive functions.

Hi

To control a visco fan clutch a low frequency PWN signal is needed ideal 1 to 5 Hz

a standard Iqan PWM goes only as low as 10 Hz.

is it a problem to use a Dout and plus this output? using a timer and change the on period?
