Hi

Here's an example to detect communication failure from whichever protocol. You can use any tag with any type, what's important is that this tag must be external and connected to the system (S7) you want to supervise.
You could change a tag value, and this tag be used in Alarm Logging to generate an Alarm

DWORD dwState;

GetTagDWordState("tag_from_S7",&dwState);

if (dwState)
{
do if communication error occur
}
else
{

do if communication is ok

}
