Automatic RAM Fill
When a Task is run and it calls for a data file to be downloaded into RAM,
the 2500 will fill RAM with a specific data pattern depending on how this
field is set.
•
None
—RAM is not changed from its current state. The file will
download and write over the current contents.
•
Default
—RAM is initialized to the unprogrammed state for the
device type selected. This will not always be the same value since
some devices are all 0s and others are all 1s in their blank
(unprogrammed) state.
•
Specific
—When selected, a second field appears on the screen,
allowing you to choose a 2-digit hex value to use when filling RAM.
The other parameters listed in the Memory Device Parameters dialog box
are not normally used when programming with a 2500. Refer to
TaskLink’s online
Help
for a description of these parameters.
Data Sumcheck
This option enables TaskLink to perform a check on the integrity of the
data in RAM. We strongly recommend that you set this option to help
reduce programming errors.
When the sumcheck of the programmed device is entered in this field,
TaskLink compares it to the RAM sumcheck after downloading a file or
loading from a master device. If the sumchecks do not match, TaskLink’s
red warning box displays both sumchecks, and the Task stops. TaskLink
also monitors the RAM for any changes during programming.
This command is available only through the
Edit Task
dialog box. From
that box, select
<More>
and the parameter is displayed on the
More
Task Parameters
window.
Other TaskLink Parameters
Several non-mandatory parameters for both memory and logic devices
are available from other pull-down menus on the main screen. The next
sections describe these menus in the left-to-right order that they are
displayed on TaskLink’s main screen.
TaskLink supports a family of Data I/O programmers, each with unique
requirements. Only those commands that are used with the 2500 are
described in this manual. Information on all TaskLink commands is
available by pressing
F1
to invoke TaskLink’s online Help.
Setup Menu Options
Most of the available choices from this pull-down menu have been
described in previous sections. The
Select Devices...
and
Select Process...
operations (see Figure 3-12) are the same commands that were selected in
the
Edit Task
dialog box to create a Task. Use these selections after a Task
has been loaded to select a device or process not included in the Task. Use
these commands when you want to run a job once and do not want to
create a new Task to do it.
