Cross Triggering Setpoints
From version V10.03.20, the SA300 provides cross triggering between multiple
devices via the Ethernet for synchronous event capture and recording.
When a setpoint is operated, the device sends a broadcast UDP message across the
network using one of the sixteen triggering channels. All devices that have a setpoint
programmed to respond to this trigger act in response. The cross triggering delay is
normally less than one cycle time.
To send a cross triggering message, put an “EXT TRIGGER” action into the setpoint
actions list and select one of the sixteen triggering channels as a target. In all
devices, which you want to respond to this message, select an “EXT TRIGGER”
group in the setpoint triggers list and specify the channel through which the device
would receive messages.
