exchanged with the 24 byte Output data.
With the 24 byte Output data it is possible to insert other parameters of the Flow meter in the same way
used with the Acyclic Service and Class 1 and Class 2 Master.
The reference to the Configuration string in the GSD file is:
------------------------------------------------------------------------
Module = "24 Byte Input/Output" 0xC0,0x17,0x17
5
EndModule
------------------------------------------------------------------------
The settings in the GSD file for to use this configuration is:
--------------------------------------
SlotDefinition
Slot(1) = "Process Data" 5
EndSlotDefinition
--------------------------------------
The Configuration correspond to 24 bytes Input/Output.
For details about the type of the data see the Section 2 Cyclic Service below in this document.
NOTE: Any other configuration will not be accepted.
1.5. SLAVE DIAGNOSTIC AND ALARMS
The module support the Diagnostic and Process Alarms for monitoring Flow rate with four thresholds.
With the Acyclic Service and a Class 1 or Class 2 Master and the relative Acyclic Slot and Acyclic Index
it is possible insert four thresholds for monitoring the Flow rate.
The thresholds are:
Flow rate High Alarm
Flow rate High Warning
Flow rate Low Warning
Flow rate Low Alarm
The control is implemented for the Flow rate in technical unit only.
After the insertion of the four thresholds of the Flow rate in technical unit, with the Acyclic Service and
the relative Acyclic Slot and Acyclic Index, it is necessary to enable the control of the Flow rate.
With the Acyclic Service and the relative Acyclic Slot and Acyclic Index it is possible to enable the
control of the Flow rate and if the value of the Flow rate measured by the Flow meter, exceed one of the
thresholds, a diagnostic message in sended to the master.
With the Acyclic Service and the realtive Acyclic Slot and Acyclic Index it is possible to enable the DPV1
Process Alarms for the masters that support this information.
The Process Alarms are set when the value of the Flow rate measured by the Flow meter exceed one of the
two thresholds High Alarm or Low Alarm.
Diagnostic message in details:
The standard diagnostic consists of 6 bytes and in addition, the alarm mechanism with extensions is used.
