3.9 Extended functionality for WinCC controls
Two new controls were introduced in WinCC V7.4:
●
WinCC BarChartControl
Display of archive tags in a bar chart
●
WinCC SysDiagControl
System diagnostics of the controllers "S7-1200" and "S7-1500"
You can find additional information under ""SIMATIC S7-1200, S7-1500 Channel" channel
DLL (Page 96)".
Additional function extensions are available with WinCC OnlineTrendControl and WinCC
AlarmControl.
Limit monitoring in WinCC OnlineTrendControl
As of WinCC V7.4, messages for limit violations are also displayed in WinCC
OnlineTrendControl.
For process tags with configured limit monitoring, you see the assigned messages directly at
the trend value:
● A red symbol signals a violation of a (high or low) limit.
● The tooltip contains the message number, message text and info text of the message.
● You jump directly from WinCC OnlineTrendControl to the assigned process picture via the
function "Loop in Alarm".
PCS 7 settings in WinCC AlarmControl
When you use PCS 7, you can specify whether you want the PCS 7 settings to be applied in
WinCC AlarmControl.
The new object property "IgnoreGlobalSettings" determines whether the central alarm system
settings from the "PCS 7 Alarm Configuration Editor" are taken into consideration.
