10. Set the Send Date & Time to enable or disable Date and Time transfers and enter
interval between Date/Time transfers. Date/Time transfer may be enabled only if the
topic corresponds to SACO 100M device and should not be enabled for other SPA
bus devices.
11. Set the event File Name. Enter file name where events will be saved. Several topics
may use the same event file. If this field is left blank or Poll Events checkbox is not
checked then events are not recorded to the file. If some event is received then this
event data is written into the file. Events are stored as character strings, each event is
stored in one row in the following format:
P TTT YYYY/MM/DD HH:MM:SS Event Value
Where:
P TTT -- Port number and Station Number; these fields are necessary
because several topics may use the same event file;
YYYY/MM/DD HH:MM:SS -- date and time when event was received;
Event -- received event; event can contain its own time; (Refer to SPA bus
Communication Protocol for event formats.)
Value – data value for analogue events.
12. Enter the value in the Maximum Number of Items in Read Command field to
indicate how many data items can be requested in one read command. If this field
contains 1 then only one data item will be requested by one read command; this
choice should be used if request of several consecutive data items in one read
command can cause error responses (for example, if some requested data is not
available). If value in this field is greater than 1 then up to Maximum Number of
Items in Read Command items will be requested by one read command. The default
value is 1.
Note. If the Maximum Number of Items in Read Command value is too great for given
SPA device (Station reply with error message "Message from master too complicated for
the slave" and quality of some values is bad), then decrease this value.
13. Click on the Ok button.
