1. 4 Watchdog hardware tripped because the TestPlan forced the trip Some of the incident codes can be disabled in the Cell Assistant preferences pages Disabling an incident code merely permits the watchdog mechanism to keep updating the external watchdog hardware i e keep it alive even though the incident occurred The incident code will still be set such that an enabled limit handler can still detect and process the incident as needed 3 Cell Assistant updates all virtual channels at 20Hz in a highly synchronized fashion TestPlan calculated channels take a disproportionately long time to compute because they require the DSBasic engine to interrupt the currently running TestPlan in order to execute the DSBasic code for each function Certain DSBasic code functions in the running TestPlan are NOT interruptible which may significantly delay computation of the TestPlan calculated functions In order to not destroy the tight synchronization of all other channels the computation of TestPlan calculated channels will be delayed in these instances and the TestPlan Calc Overrun channel will be set to TRUE It will be set back to FALSE as soon as the TestPlan calculated channels resynchronize with the rest of the system 4 Logging to data files normally occurs with no errors Effective with Release 1 3 data files now grant READ share permission to other applications even while they are opened and being written to by a running TestPlan Even though C

Cell Assistant for Windows V 1 3 User s Manual Virtual Instrument Panels Page 10 5 The PushButton control also has a digital input feedback channel associated with it The value of this channel determines the color and text of the button Using a separate feedback channel in this way allows the creation of closed loop button operations If the feedback feature is not needed the digital output channel can also be used as the feedback channel StripChart The StripChart control allows up to 4 Analog channels to be continuously plotted in real time The Y axis scale information for only one channel is displayed at a time Click the Channel button to cycle through the Y axis information for the other channels The color of this information will match the color of the appropriate channel on the stripchart This control performs lots of calculations in order to get all data to be optimally drawn in the overall bounding rectangle of the control At times the width of the stripchart can change drastically e g be reduced by 50 percent for no obvious reason For example the channel name is changed slightly and now the width of the stripchart is halved This can be confusing at times so here is an explanation of what is happening Given the size of the bounding rectangle the control first computes all margins top bottom left and right that is used for X and Y axis information captions etc This is determined by the length of these text
