and Level Low (o) link types when polling.
These link types wait for an event on a single discrete input. This event can be an edge (rising or
falling) or level (high or low). This link type may use all inputs unless the a Communication DI/O is
installed, in which case the CPU inputs may not be used.
This link type is similar to Inputs, Multiple (Level only) with the following differences:
• Inputs, Multiple: allows up to 16 inputs to be evaluated at once.
Inputs, Single: allows only one (1) input to be evaluated.
• Inputs, Multiple: allows waiting for level events only.
Inputs, Single: allows waiting for either a level or edge event.
• Inputs, Multiple: for DI/O modules, usable inputs are limited to inputs 0-15 of one DI/O module.
Inputs, Single: any discrete input can be used on any DI/O module, except the CPU inputs when
the Communication DI/O is installed.
Using with the Link Type and Link Value Dialog Box
1. Under Link Type Category, select System-wide (Basic, non-axis).
2. Under Link Type, select Inputs, Single (Level/Edge).
3. Under Link Condition, select the type of the event you want to wait for (rising or falling edge, or on
or off level).
4. Under Link Condition, select the device whose discrete input you wish to use (either CPU,
Communication DI/O, or Sensor DI/O).
5. Under Link Condition, select the input number on that device.
Using without the Link Type and Link Value Dialog Box
1. Select a Link Type:
Use 'I' to wait for a rising edge, 'I' to wait for a falling edge, 'O' to wait for an input to be on, or 'o'
to wait for an input to be off.
2. Calculate a Link Value:
This will select the input to use. Begin with the input number from the device (0 17 for DI/O
modules or 0-1 for the CPU). If the input is on a Sensor DI/O, add 32 to the input number. Use
this value for the Link Value (e.g., CPU input 1 will use a Link Value of 1, Sensor DI/O input 4 will
use a Link Value of 32 + 4 = 36).
Example 1:
Link Type: InputHigh (O)
Link Value: 16
Link Next: 11
This link waits until input bit 16 of the Communication DI/O is ON before going to step 11.
