“Simple Samples” are small projects that demonstrate simple features. The target is give a quick overview about the theme and be used as start point for related discussions. Follow there are a short description and the configuration main steps.
Description:
Many applications demands that an alarm would be acknowledge by the PLC or that the PLC receive a status if a message was acknowledged.
In this sample project, an alarm (“Alarm 0 active”) could be acknowledged by setting a variable and its status (acknowledged) could be monitored in others variables.
Requirements: WinCC V7.3.
Project with a minimum configuration (stop button See references “WinCC V7 – Simple Sample: Discrete Alarm” https://support.industry.siemens.com/tf/br/en/posts/135060/).
Principle:
1 – Alarms are defined from bollean variables (trigger variable)
2 – A bit of a Word /Dword variable can be set as acknowledge functions (i.e. setting this bits, the PLC sends a command to acknowledge the Alarm in HMI). (Alarm properties → Tags → PLC → Tag/bit)
3 – To send a feedback that a alarm would be acknowledged to the PLC, it is necessary to set a pair of bits from another Word /Dword variable (Alarm properties → stauts → setting → Tag/bit). (it is set the first bit, the pair is given for the rule bit+8). The first bit show the status of message active or not, the second if it was acknowledged or not.
Configuration main steps:
PLC acknowledges a alarm
PLC becomes a feedback of an acknowledged a alarm

Project:
Due a size / format restrictions, the project are first compacted with 7z format (project.z7) and after that attached to a zip archive (data1.zip, data2.zip, data3.zip).

Hi, thank for your sample project. But how to include in the text of the alarm messages dynamic values from AS ? Benoit |
