[Acc72E profibus input channel issue]

I am using an Acc72E profibus card - 603777-103 to communicate the Power PMAC rack to the master cell PLC. I am having an issue with multiple cards where the input bytes are maxing at 255. I can disconnect the master PLC and profibus cable but the 72E card input/output values are still moving. I load the sycon configuration for our equipment but that has little to no effect. Out of seven cards, I have three that work.

 

Below is an example of what I am using to test in a plc to confirm if the card is working properly.

 

Acc72E[2].Output2[0] = OutputByte0;

Acc72E[2].Output2[1] = OutputByte1;

Acc72E[2].Output2[2] = OutputByte2;

Acc72E[2].Output2[3] = OutputByte3;

 

InputByte0 = Acc72E[2].Input2[0];

InputByte1 = Acc72E[2].Input2[1];

InputByte2 = Acc72E[2].Input2[2];

InputByte3 = Acc72E[2].Input2[3];

 

If there are any settings or suggestions for this issue I would greatly appreciate it. I have all cards on hand and am able to perform tests quickly.

[C from script compile issue]

I am having issues compiling a C# from script code on a power pmac 460EX UMAC system. This is the fourth system with the latest firmware and latest powerpmac IDE: 2.0.2.14 firmware and 2.0.3.40 IDE. Below is the messages that showed up in the err.log file. I am willing to share all project code for this issue; the usercde.C can be changed from compile to content and the project will download. I reverted the project back to script kinematics and it is running fine, however I want to make them all the same to have C# kinematics from script. Any information would be appreciated.

[Using CfromScript() - Calling C Functions from the PMAC Script Language]

Charles,

 

I was hoping you could provide a small example of how to implement C functions in the realtime routine for specifically kinematics. Does the C application need to be called in the realtime PLC to use with kinematics? I have a two motor kinematic equation (motor 1-X and motor 2-Y) that has a fairly simple equation. We are hoping to see the performance gains of moving the kinematic calculations to the C realtime routines.

 

Thanks!

[CPU Power up problems]

On some of our PowerPMACs we experience a problem with power cycles to the controller. As viewed through serial, the boot sequence gets stuck in a loop and never fully boots. It starts to boot, doesn't get very far, and then restarts. It can take two or three power cycles sometimes for it to boot properly. Is this the same issue the ECO is supposed to fix?

 

I am working with user jhendges on a similar issue. We had a Power PMAC cpu stop booting right upon power up at the ram check portion of the boot. We are sending in for a diagnostic test as this card has done this on every boot and has not successfully boot up.
