10. Operation
The VOLT 100 series makes analog measurements either under the direction of SURVEYOR or the
data logger.
10.1 SURVEYOR control
SURVEYOR sets up the VOLT 100 series to start making measurements, display data, and store
that data to a computer. For more information, see
Measurement quickstart using SURVEYOR
10.2 Data logger control
Upon compiling the program, the data logger sends information to each VOLT 100 series about
every relevant sequence, scan, and measurement. The data logger uses a data sync to initiate
measurements on the VOLT 100 series. Because measurements can be made in multiple scans,
slow sequences, sub-scans, and subroutines, the data logger firsts sends a message to the
modules indicating which measurements are to be made upon the next data sync.
When the VOLT 100 series receives a sync signal, it begins making measurements. The
measurement order on the VOLT 100 series follows the sequence of the instructions addressed to
it within the current active scan of the data logger program. After the measurements are
completed, it sends the data to the data logger for processing.
10.3 Measurements
Because the VOLT 100 series makes measurements similar to the GRANITE 6 series data logger,
refer to the
GRANITE 6 Measurement and Control System
manual for in-depth measurement
details. Information specific to the VOLT 100 series is provided in the subsequent sections.
