To activate the Alert Mediator, you have to choose in Alert the m_pcvue.dll in the following menu:

Configuration/Options – supervision tab

Then, in the Alert explorer, right-click on Tags and choose import/m_pcvue.dll

Select the VAREXP.DAT file from your PcVue project.

Then, select your variables, specify the On-call-management group that will be associated to these variables, add them and close this window by selecting OK

Then you’ll find your variables added to Alert

2) How to check sent information between Alert and PcVue

Alert and PcVue use System variables (declared in PcVue) to exchange information.

These variables are:

• SYSTEM.INFO.DATA_OUTPUT
• SYSTEM.INFO.CMD

SYSTEM.INFO.DATA_OUTPUT is used to send information from PcVue to Alert.  SYSTEM.INFO.CMD is used to send information from Alert to PcVue.

Both are text variables that can be displayed in PcVue or written in a text file.

Alert is directly connected on these variables by using DDE communication.

These variables can be useful to check to see what information is being exchanged between PcVue and Alert.
