Signals are only logged when the Signal Analyzer window is opened. However, in general,
do not keep the window opened unnecessarily as the logging routines can cause a noticeable
degradation of server responsiveness when the server is running on a slower PC.
The File Menu
The only currently implemented commands in this menu print the input and output
signal lists for the currently selected signal block (
File | Print Signal
List | Selected
), or for all active signal blocks (
File | Print Signal List | All
). This
printout can be used to create matching
Intersystem Communication
symbols in
SIMPL Windows. To this end, the lists contain signal labels identical to the labels
used in that symbol.
The Simulate Menu
This menu contains the following commands for simulating signals. Simulated
signals are added to the Signal Log on the bottom portion of the window, just like
real signals.
•
Simulate | Incoming
simulates receipt of the signal currently selected in the incoming
(“CS-to-PC”) signal list. Before issuing the command, set the value to be “received”
with the signal by entering data into one of the three value frames. The frame to use is
based on the signal selected. This function is also available by clicking the
rx
button
under the incoming signal list.
•
Simulate | Outgoing
simulates receipt of the signal currently selected in the outgoing
(“PC-to-CS”) signal list. Before issuing the command, set the value to be transmitted
with the signal by entering data into one of the three value frames. The frame to use is
based on the signal selected. Note that simulating an outgoing signal when the system
associated with the signal block is not connected has no practical effect. This function
is also available by clicking the
tx
button under the incoming signal list.
The Log Menu
This menu contains the following commands that affect the Signal Log display:
•
Log | PINGs and PONGs
.
Uncheck this item to suppress logging of the
Ping
and
Pong
signals available in the system signal blocks. The intent would be to keep the log
uncluttered when a control system has been programmed to ping to server on a
periodic basis.
•
Log | Clear
clears the signal log.
•
Log | Timestamps
.
Selecting this option puts a checkmark next to it and henceforth all
log items will contain a timestamp of the form
hh:mm:ss
(24-hour clock) at the
beginning of each line. Selecting the command again removes the checkmark and
timestamps will no longer be included in the log.
•
Log | Debug Info.
Selecting this option puts a checkmark next to it and henceforth all
logged signals as well as the
rx
and
tx
buttons will contain additional signal
information.
The log items normally contain an element of the form [
n
] where
n
is the
signal number relative to the start of the signal block. When
Debug Info
is
checked, this element takes on the form [
com
(
ch
):
m
=
n
] where
com
is the
COM Settings name; (
ch
) is the Virtual COM Port channel number (included
only when > 1);
m
is the absolute signal number (
n
+ the signal block’s offset)
(included only when different from
n
—
i.e.,
only when the offset is non-
zero); and
n
is the relative signal number (as above);
The
rx
and
tx
buttons each normally contain a number,
n,
the relative signal
number of the currently selected signal from the respective signal list. When
Debug Info
is checked, the buttons each contain additional information of the
form
m
=
n
where
m
is the absolute signal number (included only when
different from
n
).
Selecting the command again removes the checkmark and the additional
information is excluded.
