252 PMCS Interface Toolkit
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 reflec t 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 changi ng 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.
