mapp Services V5.16
Requirement
The temperature of a furnace should be monitored in the application. If the temperature becomes too high, a red light should be illuminated and the motor should be cut off.
Solution
•Component list
•MpAlarmBasic (own MpLink): Centralized alarm management
•MpAlarmReaction(MpLink from MpAlarmBasic): Can optionally be used to assess reactions locally (e.g. in other program tasks than those of the MpAlarmReaction component)
•MpAlarmSet (MpLink from MpAlarmBasic): Sets a user alarm (e.g. temperature too high)
Connection diagram
Using the mapp components
Any alarm (user alarms and mapp alarms) can trigger multiple reactions, and a reaction can be triggered by more than one alarm. Which reaction is triggered by an alarm must be configured in Automation Studio.
Configuration in Automation Studio:
MpAlarm supports a total of 32 reactions.
They are displayed on MpAlarmBasic as a bit-coded 4-byte value and can also be evaluated with the MpAlarmReaction function.
The user can decide about the significance of the individual reactions. In other words, the application program defines how the machine should ultimate react.
