# External Event Signals

The External Event signals are the following:

[out] ExternalEvent0

[out] ExternalEvent1

[out] ExternalEvent2

[out] ExternalEvent3

[out] ExternalEvent4

[out] ExternalEvent5

[out] ExternalEvent6

[out] ExternalEvent7

[in] ExternalEventAck0

[in] ExternalEventAck1

[in] ExternalEventAck2

[in] ExternalEventAck3

[in] ExternalEventAck4

[in] ExternalEventAck5

[in] ExternalEventAck6

[in] ExternalEventAck7

Between ExternalEvent0 - ExternalEvent7:

Setting the ExternalEvent# bit triggers an event to run in the Spreadsheet of the vision system. This event is user configurable to run a tool, clear a counter or whatever is needed in the job if an event can be used. The rising edge of the ExternalEvent trigger bit causes the vision system to process the action associated with the external event. Upon initiation of the external event, the vision system sets the External Event Ack bit to 1.

Between ExternalEventAck0 - ExternalEventAck7:

These bits are for indicating that the ExternalEvent command was received. The ExternalEventAck# bit is set to 1 when the vision system receives the ExternalEvent# set to 1. It stays set to 1 until the PLC clears the External Event# bit to 0. If the external event could not be triggered, the Error bit is set to 1.
