• Auto1-2 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 cascade operation or manual operation to auto operation.
• Man1-2 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 cascade operation or auto operation to manual operation. A single
registration is possible per control output terminal block. This setting is not allowed
for control output terminal block 3.
• SPNumber0 to 3 bit
Select when registering a contact input for switching the SP. Four contact inputs
(4-bit binary) are used to specify SP numbers [1] to [8]. For example, set
SPnumber1bit and SPnumber2bit to ON to specify SP number [6].
Contact outputs that can be registered to [SPnumber0bit] to [SPnumber3bit] are
[DI003 to DI006] of loop 1 and 2 control output terminal block and [RI009 to RI012]
of the control DIO expansion terminal block. Only the required number of bits can
be registered. For example, if you are switching among SP numbers [1] to [3],
register only [SPnumber0bit] and [SPnumber1bit] (2 bits).
If [SPnumber0bit] through [SPnumber3bit] that corresponds to the MSB is set to
[DI006] of loop 1 and 2 control output terminal block or [RI012] of the control DIO
expansion terminal block, the required number of bits of contact inputs—[DI003 to
DI006] for the control output terminal block, [RI009 to RI012] for the control DIO
expansion terminal block—are automatically registered.
Note
• For contact inputs [SPnumber0bit] to [SPnumber3bit], the loop number for which the SP
number is to be switched can be selected. For the operating procedure, see the
explanation for [SP No. selection source] on page 4-8 .
• Only a single system of SP assignment using contact inputs is available on each CX2000.
• ProgramRun ← selectable only during program control
Select to register a contact input for starting the program operation.
• ProgramReset ← selectable only during program control
Select to register a contact input for resetting the program operation.
• Hold ← selectable only during program control
Select to register a contact input for holding the program operation.
• Advance ← selectable only during program control
Select to register a contact input for advancing the program operation.
• PatternNo0 to 4bit ← selectable only during program control
When registering as a contact input for switching the program pattern.
When specifying program pattern numbers in binary
5 contact inputs (5-bit binary) are used to specify the pattern number (1 to 30). For
example, set [PatternNo1bit] and [PatternNo2bit] to ON to specify pattern number [6].
Contact outputs that can be registered to [PatternNo0bit] to [PatternNo4bit] are
[DI001 to DI005] and [DI201 to DI205] of the control output terminal block and
[RI001 to RI005] of the control DIO expansion terminal block. Only the required
number of bits can be registered. For example, if only 2 bits are needed to make
the switch, register only [PatternNo0bit] and [PatternNo1bit].
If you place the cursor on [DI001] (with the control output terminal block) or [RI001]
(with the control DIO expansion terminal block) and press the soft key that includes
the maximum pattern number to be specified, contact inputs of the required
number of bits, [DI001]-[DI005] (control output terminal block) or [RI001]-[RI005]
(control DIO expansion terminal block), are automatically registered.
When specifying program pattern numbers in binary-coded decimal (BCD)
(version 3.20 or later)
For the setting procedure, see section 4.19, “Settings for Switching the Program
Patterns Using Contact Inputs with BCD Codes (Version 3.20 or Later).”
