PTQ-PDPMV1 ♦ Quantum Platform
PROFIBUS DP Master Network Interface Module for Quantum
StatOut.ModuleStatus_LastinMailBoxMessageID <>
StatIn.MailBoxData_CurrentInMailboxControlIndex
The module will increment StatIn.MailBoxData_CurrentAlarmControlIndex when
the module contains alarms to be sent to the processor. The function block
implementation will then copy the alarm to the appropriate data structure. The
function block implementation uses the following expression to verify if any
alarms are available:
StatOut.ModuleStatus_LastAlarmControlindex <>
StatIn.MailBoxData_CurrentAlarmControlIndex
After the alarm is copied, the logic then updates the alarm index for handshaking
purposes:
StatOut.ModuleStatus_LastAlarmControlindex :=
StatIn.MailBoxData_CurrentAlarmControlIndex
Please refer to Mailbox Messaging (page 151) for further information about each
mailbox parameter.
The following section provides examples of data structure groupings.
