5.6.28 PID Step Ref L, PID Step Ref M, PID Step Ref H
Three digital inputs can provide up to 7 different Step References (setpoints). Refer to section 6 PID
Control Group (PID) on page 220 for more details.
5.6.29 Digital Input Terminal Control
An On Delay and/or Off Delay time can be applied to all digital input terminals. The default setting
for all terminals is enabled "1" (On) which applies one On Delay (IN-85) and one Off Delay (IN-86)
filter time to all terminals. To disable the delay time for a specific terminal, set the bit for the
terminal to "0" (Off). Note: Longer time settings will delay the response of the input.
Additionally, the digital inputs can be configured independently as a normally open input or a
normally closed input (IN-87). The status of the inputs can be viewed at IN-90.
