Single block
Created using CX-Process Tool (purchased separately) and transferred to Loop
Controller.
The time from external input of analog signals up to external output of analog signals
on a single control loop depends on the function block's operation cycle and the
CPU Unit's cycle time.
0.01, 0.02, 0.05, 0.1, 0.2, 0.5, 1, or 2 s (default: 1 s) (See note.)
Can be set for each function block.
Note: 0.01, 0.02, and 0.05 s cannot be set for some blocks.

PID with 2 degrees of freedom
Any of the following function blocks can be combined:
Basic PID control, cascade control, feed-forward control, sample PI control, Smith
dead time compensation control, PID control with differential gap, override control,
program control, time-proportional control, etc.
