Registering Contact Inputs
• Module
Select the terminal block for contact input settings from the list below. The contact
input number in the Relay Operation settings field will change per the selected
terminal block.
CTRL1-DI (control output terminal block 1): DI001–DI006
CTRL2-DI (control output terminal block 2): DI101–DI106
CTRL3-DI (control output terminal block 3): DI201–DI206
CTRL1-DO (control output terminal block 1): DO101-DO106
CTRL2-DO (control output terminal block 2): DO201-DO206
CTRL3-DO (control output terminal block 3): DO301-DO306
EXT1-RI (control expansion DIO terminal block 1): RI001–DI012
EXT1-RO (control expansion DIO terminal block 1): RO001-RO012
INT-SW1 (internal switch): SW01-SW12
INT-SW2 (internal switch): SW13-SW24
INT-SW3 (internal switch): SW25-SW36
For a description on the terminal arrangement, see page 2-6 to 2-7.
• Contact input information registration
Select the contact input information for each contact input registration number from the
following. For a description on the method of detecting contact inputs, see page 1-24.
• AllControlStop
Select this when registering as a contact input for stopping the control operation of
all internal loops.
• AllControlStart
Select this when registering as a contact input for starting the control operation of
all internal loops.
• ControlStart/Stop (1 to 6)
Select this when registering a contact input for starting the control operation of
each internal loop. The rising edge of the signal signifies “Stop”; the falling edge of
the signal signifies “Run.”
For a control output terminal block, up to two loops that can output signals can be
registered per block. In the cascade mode, registration is allowed only for loops 2 and 4.
• Remote/Local (1 to 6)
Select this when registering a contact input for switching remote operation and
local operation for each internal loop. The rising edge of the signal signifies
“Remote”; the falling edge of the signal signifies “Local.”
If program control is ON (only on models with the program control option),
switching is performed between program operation and local operation. Remote/
Local (loop 1) or (loop 3) is selectable only when program control is ON.
For a control output terminal block, up to two loops that can output signals can be
registered per block. In the cascade mode, registration is allowed only for loops 1 and 3.
• Auto/Man (1 to 6) ← not selectable during cascade control
Select this when registering a contact input for switching auto and manual (Man)
operation for each internal loop. The rising edge of the signal signifies “Auto”; the
falling edge of the signal signifies “Man.”
For a control output terminal block, up to two loops that can output signals can be
registered per block.
• Cascade (1-2 or 3-4) ← selectable only during cascade control.
Select this for internal loops 1-2 or 3-4 when registering a contact input for
switching from auto operation or manual operation to cascade operation.
Note
[Cascade1-2] or [Cascade3-4] does not appear as a selection, if the [Control mode] box
under [Control] > [#1 Control action, Input setting] is not set to [Cascade].
