Troubleshooting
Assertion Error
Q: While switching between InTouch's Runtime and Development modes, the
program crashed with an Assertion Error.
A: This is a problem with InTouch Wonderware, not the GE PMCS Wizards. It
occurs rarely during the development phase, and is not seen once a stable application
has been developed and put into use. Reboot the computer and restart the application.
EPM 3710/EPM 3720 – no data or incorrect data displayed
Q: The values on the EPM 3710/3720 wizards come up showing zeros or incorrect
data.
A: The EPM 3710/3720 wizards require you to click the Refresh button on the
wizard before the display is updated. Also, the first time the wizard is displayed, it
may take a few moments for the DDE conversation to be established and data to be
displayed.
EPM 3720 – KVAH import values incorrect
Q: On the EPM 3720 Tabular data screen, the KVAH import value does not equal
the value of KVAH total or KVAH net when KVAH export equals zero.
A: Some rapidly changing values and/or values requiring extensive calculations
cannot be updated on the wizards quickly enough to reflect the data displayed on the
device in real time. Be patient while the software catches up with the device.
Long update when changing setpoints
Q: I attempted to change a device setpoint (such as changing the VT connection type
from WYE to DELTA). It took a long time to update the Wizards setpoint tab to
reflect the changes.
A: When changing setpoints, which are polled very slowly, the display may take a
long time (a minute or more) to update. This means the metering data will be
postponed while the display updates. Setpoint changes are a relatively rare change to
make - please be patient during the delay.
