3.1 Mailbox Message Queuing
The PDPMV1 gateway operates asynchronously on the Mailbox Messages and
as such provides for the queuing of the messages as they are received. The
queue sizes used in the gateway are as follows:
Queue Type Queue Size Max Description
Output Message from processor 20 Number of messages that the ProLinx
gateway will queue by type of message. Note
that status of the queues can be monitored
via the Queue Message Count values.
Input Messages for processor 20
Alarm Messages from slaves for
processor 20
3.1.1 Queue Timeouts
The PDPMV1 gateway will only allow a message to stay in a queue for up to 10
seconds. If the PROFIBUS Master (for output messages) or the processor (for
input and alarm messages) has not successfully received a message within 10
seconds, the gateway will clear the message out of the queue.
