Chapter 4: Operation REACT Input Signals 1001 to 1012 Inputs 1001 to 1012 (only) may be used by the eV+ REACT and REACTI instructions. See the eV+ Language Reference Guide for information on these instructions. If you are going to use these instructions, you should plan your digital I/O channel usage accordingly. In addition to functioning as normal input signals, all input signals can have the following special uses: l Fast DIO eV+ Interrupt Events (INT.EVENT) l Robot and Encoder Position Latch Fast DIO interrupt events (using INT.EVENT) require the optional eV+ Extensions License.
When the program task priorities are properly set, there is a 1 ms maximum latency for the fast inputs when used with the eV+ INT.EVENT instruction. See the eV+ Language Reference Guide for a description of the INT.EVENT instruction. Output Signals The XDIO connector handles output signals 0001 to 0008. Refer to the following table for out- put specifications. The locations of the signals on the connector are shown in the table XDIO Digital I/O Connector Pin Assignments on page 46. The XDIO connector provides separate pos- itive and negative connections for each channel (no internal common connections). This allows the choice of wiring for current-sourcing or current-sinking modes.
