Integrated Loop Control and Sequence Control

An engine for controlling analog quantities (e.g., temperature, pressure, flowrate) is built into the CPU Unit together with the engine for executing sequence control, delivering high-speed sequence control and high-speed, advanced analog quantity control in a single Unit.

High-speed sequence control functions can be used directly for

high-speed, advanced loop control.

Sequence control: Executes 20-Kstep ladder programs in 1 ms (with basic instructions only). PCMIX = 7.4 LD or OUT executed in 40 ns

Loop control: Executes PID operations for 20 loops in up to 10 ms. This is a guide for general applications. (See note.)
