lite
the test run or preview on the master eDAQ
lite
/eDAQ, which results in the
de-assertion of the MSR clock source. When this occurs, each slave detects the loss
of the MSR clock source and stops the test run or preview synchronously.
TCE gets SIF file data from the eDAQ
lite /eDAQ nodes in a serial manner. TCE
appends a qualifier string to the default PC file name to distinguish the SIF files. For
example, if the test setup file name is MyTest.tce and there are three networked nodes,
the default SIF data file names are MyTest (1 of 3).sif, MyTest (2 of 3).sif and MyTest
(3 of 3).sif. TCE applies the same default naming convention when transferring files
from a PC Card.
4.8.1 Using Remote Control with a Network
For remote control with an eDAQ
lite
/eDAQ network, use the remote control hardware
(i.e., the ELDIO interface hardware) only on the master node. This applies to both the
test run control input and the optional test monitoring output digital lines.
NOTE
The preview run option is not supported in remote control mode.
The slave eDAQ lite /eDAQ systems automatically start a new test run immediately
after test initialization and after each test run stops, as long as the remote control is
not suspended. Because of this, be careful to not start the master until the slaves are
all running and waiting for the master to assert the MSR clock source. The green and
yellow front panel LEDs blink in unison when the slave is in this ready state. Failure to
do this prevents synchronization of the slave and master data.
The automatic test runs prevent normal actions such as removing the PC Card or
ending the test after a test run stops. To perform these actions, first suspend the
remote control and then stop the test. This should be done with the run control switch
on the master set in the off position so each slave increments the test run number and
creates a new set of DataMode channels in the SIF file. Suspend and resume the
remote control mode using the same TCE interface as a stand alone eDAQ
lite
.
NOTE
When the master eDAQ
lite
/eDAQ reboots after a power failure or an error reset, the
system suspends the remote control mode to prevent starting a new test run on the
master. In this scenario, stop all slave eDAQ
lite
/eDAQ systems with test runs still in
progress and resume remote control on the master so that all nodes start the next test
run in sync.
It is advised to experiment with using remote control for an eDAQ
lite
/eDAQ network
and become thoroughly familiar with the details involved prior to using it in the field.
