Metrohm Sample Processors are designed to communicate with other
instruments. In particular, this includes the coordination between the
Sample Processor and devices connected to it. In the method se-
quence the SCAN command can be used to check whether an instru-
ment is ready or to ask for an acknowledgement after a measurement
has been made. However, it may happen sometimes that problems oc-
cur during a determination run and that the expected signal from the
connected instrument is not received. This is known as a timeout.
This means that it is possible to define a maximum waiting time that will
always be allowed to elapse if a timeout occurs. In addition, the behav-
ior of the Sample Processor when this waiting period has elapsed
(SCAN timeout) can also be defined.
