Due to the different loading that can be placed on the communication
processor in the PLC/5 processor, transfer times are not consistent every
time. For each test, 20 readings were taken to calculate the numbers. We
present the minimum, maximum, and average values.
Setup #1
NOCV = 1 (VME coprocessor does not constantly read PLC processor)
Copy to global VME RAM on-board the PLC processor at 0xA00000
Programming terminal not attached to PLC processor
