RG
For digital outputs, the channel number is selected by choosing the appropriate wiring diagram, rather than setting a
separate control (as is the case for analog channels).
The controls in the lower part of the properties pane select whether the control output state should be on, off, set
according to a CV value (on if the CV is non-zero, off if it is zero) or inverted.
You can also specify that the output should be pulsed – that is, set to the specified state for the indicated time, then
inverted. Thus in the above example the DT80 relay will be held closed for 500ms then released.
Action Channels
An action is used to insert a command into a schedule. Currently, two actions are available – unload data via email and
unload data via FTP.
These actions translate into commands of the form:
DO{COPYD dest=ftp://... format= sched= data= alarms= start=
and
DO{COPYD dest=mailto://... format= sched= data= alarms= start=
respectively. (See COPYD – Unload Data (P101))
 FTP Logged Data
The properties pane for the FTP Logged Data action is shown in Figure 32.
Figure 32: FTP Action setting
The upper part of the pane contains controls for specifying the unload destination – FTP server details and destination
path name. In this example, a replaceable parameter
?(serial) has been entered as the folder name. As discussed
in Unload Destination Replaceable Parameters (P107), this will be replaced with the DT80 serial number when the
unload command is executed. The file name field has been left blank, so a filename with the default format will be
generated, e.g. 077_20110303T110908.csv.
The lower part of the screen defines the other options in the
COPYD command, namely:
• unload format (CSV or DBD)
• whether data or alarm records are included, or both
• the unload time range. The end time is always "now", while the start time can be either: the earliest available
record, or the earliest record that has not yet been unloaded ("new data only"), or n minutes/hours/days ago.
• the schedules to include (on the Optional tab)
 Email Logged Data
The properties pane for an email unload is very similar. The lower part is the same as for FTP. The upper part is where
you specify the email destination – the recipient's email address (or addresses, comma separated), plus an optional
custom message subject and body.
Special Channel Types
 Reference
A reference channel gets its value from another previously measured value. Thus if you add a reference channel you will
be asked to select which existing channel you wish to reference.
Other than that, a reference channel is configured in a similar way to any other measurement channel, i.e. the same five
tabs of options are displayed.
