MTS MultiPurpose TestWare®
Model 793.71/72 Time History Output Process
Command Processes 252
Drive has an offset When enabled and relative mode is not selected, the process will start by
ramping to the first command point in the time history, and end at the last
command point in the time history, without returning to zero.
When enabled and relative mode is selected, the process will start by ramping
to the first command point in the time history, and will end by returning to the
starting point after the last specified pass is completed.
Note The command signal will not return to zero (or to the starting point in
relative mode) between files in the sequence, but will transition directly
between the last command point of one drive file and the first
command point of the following drive file.
Status Displays messages about channel mapping and full-scale status after the
application checks the mapping and unit selections on the Mapping tab. These
messages are updated each time you modify the channel, mode, or unit
selection on the Mapping tab.
The application will ensure that no two file channels are mapped to the same
station channel. When the check is complete, the application will display either
“Invalid Channel Map” or “Valid Channel Map.” The process cannot be run
with an invalid channel map.
If the mapping is valid, the application checks full scales of each channel in the
file against the range of the selected control mode for each channel. The
message “Full Scales Outside Limits” or “Full Scales In Limits” will display
the results. If the mapping is bad, the outside limits text will display.
Since an RPC time file does not necessarily have data near its full scale, the
command may not actually exceed the channel’s limits when the drive file is
played out. However, the message is intended to warn you the potential exists
for driving a channel outside its limits.
