So you may react to asynchronous events, there is the possibility to
activate a process interrupt. A process interrupt interrupts the linear
program sequence and jumps depending on the master system to a
corresponding Interrupt routine. Here you can react to the process
interrupt accordingly.
With CANopen the process interrupt data a transferred via an emer-
gency telegram.
Operating with CPU, PROFIBUS and PROFINET the process inter-
rupt data were transferred via diagnostics telegram.
SX - Subindex (5000h) for access via EtherCAT
More can be found in the according manual of your bus coupler.
