They can but what tends to happen is the dynamic brake throttle does not pause for setup, so it will set a fault in the IO station because it did not get the response it wanted (dynamic brake) it then usually causes some kind of voltage problem, faults out the IO station and the P42 can no longer be controlled by the siemens. The ALCs have since been swapped with an analog IO station, supposedly, that will correct this problem. It still has to interface thru software.
There WAS a time when the ACS 64 was functional with diesel locomotives with minimal problems. I dont know what happened. The diesel i ran with though did not have dynamic brake so im not sure if that had anything to do with it. But they can be problematic to the point where they will not even talk to each other. hell, the software version changes between 10 and 11 make ACS 64s incompatible depending on which one is leading. But SOMEHOW thru all this, a control car works perfectly fine. Control cars do not have dynamic brake control though.

No good deed goes unpunished.
