The PID-PL block supports execution rates as fast as 50ms for ACE and C200. A CM with the PID-PL block consumes
approximately 50 percent more PUs as compared to a CM with the standard PID block. A CM with the PID-PL block utilizes
circa 30 percent more MUs as compared to a CM with the standard PID block.
