*1 The controller mode must be set to Cascade Control before Automatic/Manual/Cascade Selection (A/M/C) can be
set to 2 (Cascade). In cascade control mode, operation proceeds according to the setup for the even-numbered
loop (2 or 4).
The single-loop mode is the most basic controller mode, where the module performs
computation using the control and computation function and outputs the control output
(HOUT and COUT) as defined by the output-control functions so that the process value
(PV) as processed by the Input PV-related functions approaches the control set point
(CSP) as defined by the SP-related functions.
The PV-related functions process the output from a thermocouple, RTD or other
temperature sensors according to the characteristics of individual sensors. In particular,
the filter function reduces noise and other disturbances, and the biasing functions correct
for deviations between devices. For details, see Section C3, "PV-related Functions."
The SP-related functions set up and select set points (SP), and perform processing to
prevent abrupt changes. In addition, the remote set point (RSP) can be used to receive
successive external set points. For details, see Section C4, "SP-related Functions."
The control and computation function computes control output values so that the PV
approaches the set point. The control method may be set to ON/OFF, PID, or
heating/cooling PID control to suit an application. For details, see Section C6, "Control
and Computation Function."
The output control functions process the output so that the upper limit, lower limit, or the
rate-of-change limit will not be exceeded. They also perform processing to prevent
sudden changes in the output level due to, say, switching between Automatic and Manual
mode. For details, see Section C2, "Output-related Functions."
