16.1.6.4 Application of the Status Reporting System
The purpose of the status reporting system is to monitor the status of one or several
devices in a measuring system. To do this and react appropriately, the controller must
receive and evaluate the information of all devices. The following standard methods are
used:
●
Service request (SRQ) initiated by the instrument
●
Serial poll of all devices in the bus system, initiated by the controller in order to find
out who sent a SRQ and why
●
Parallel poll of all devices
