OUT=
OUT=MAX (H1, H2, P1, P2)
OUT=MIN (H1, H2, P1, P2)
OUT=H1+H2+P1+P2
When H1 ≥ H2, OUT is H1. When H1 < H2, OUT is H2. When used as a low limiter, H2 is the lower limit value.
When H1 ≥ H2, OUT is H1. When H1 < H2, OUT is H2. When used as a low limiter, H2 is the lower limit value.
H1 is limited by the high limit value P1 and the low limit value P2.
Output is asserted when H1 exceeds high monitor value H2. (Hysteresis width is P2.)
Output is asserted when H1 falls below the low monitor value H2. (Hysteresis width is P2.)
Output is asserted when the deviation between H1 and H2 exceeds deviation monitor value P1. (Hysteresis width is P2.)
Limits input H1s deviation rate per minute to H2% on positive side and to P1% on the negative side.
Output is asserted when input H1 exceeds H2% on positive side and is within P1% on negative side compared
to inputs made one minute earlier.
Enables manual output from system console.

OUT=e-P1 · S × H1(Input H1, the dead time, is output after P1 seconds.)
OUT=(1+P1 · S) / (1+P2 · S)×H1
OUT=P1 · S(1+P2 · S)×H1
OUT=H1/P1 · S (Integration performed on input H1 in integral time of P1 seconds.)
OUT=
Set input H1 holds flag data; H2 input resets the data.
OUT=H1
OUT=H1
OUT=H1— GH2
OUT=H1
P1 switches between H1 and H2 percent data.
Switches between H1 and H2 using a P2 (%) slope for smooth switching.
Switches between H1 and H2 using P1 time data,
Switches between H1 and H2 using P1 flag data.
Inverts output when the rising edge of H1 is detected.
Pulse generation per P1 seconds.
Asserts output aftter P1 seconds.
Inhibits output after P1 seconds.
Generates pulse for P1 seconds.
Outputs the number of pulses proportional to input H
Performs integration on input H1 and outputs one pulse when the output pulse value set by P1 is reached.
Asserts output in proportion to input H1 within the P1 cycle.
Outputs a waveform with a rising slope.
OUT=LOG
OUT=10
Changes PID 1 control variables, (enables changing of PID group numbers also.)
Changes PID 2 control variables, (enables changing of PID group numbers also.)
Cycles through follow, manual, auto and cascade modes
Cycles through follow, manual, auto and cascade modes
Starts/stops PID 1 unit auto-tuning.
Starts/stops PID 2 unit auto-tuning.
Retains input H1 during outage, and outputs it as is after restore.
Raises output when H1 is ON (raise) and lowers it when H2 is ON (lower).
Resets the interlock manual mode.
