RSView32 communication to a 5550 Processor

Our ControlNet system contains multiple PLC5's, one PLC5550 and several PC's running RSView32.

Communication with the PLC5's is no problem. When communicating to the PLC5550 we are generally receiving and sending data correctly. However, when a button is depressed in RSView (and a discrete bit is commanded to be set in the 5550) we receive a message "Write to tag Model\Model_ang_set has failed: The system is low on memory"

Does anyone know what this means and how to fix it? I have looked at the processor memory and it is about 60% utilized. Also, the same message occurs on either of the PC's when the button is pressed.

In RSLogix5000 on your 5550 PLC, select Controller Properties under the Edit menu. Click on the advanced tab. Increase the system overhead time slice percentage by a few points.
