C2.6 External Output
You may switch the output between Control Output (HOUT) and External Output
(EXOUT) using the EXOUT/OUT parameter.
When EXOUT/OUT is set to 0 (Normal output), the PID computation result or some other
control and computation result is output.
When EXOUT/OUT is set to 1 (External output), the output value specified by the
External Output (EXOUT) parameter is output. EXOUT is not constrained by the upper or
lower output limit.
As an example, a sequence CPU may read the value of HOUT, correct or otherwise
process the value, and then write the processed value to EXOUT.
