DFB Acyclic Mailbox Message: Get Live List - Quantum

This acyclic message returns 127 bytes of information about the nodes on the

network. Each byte holds the node type for one bus subscriber (node or device).

The position of the byte in the response data corresponds to the address (0 to

125) of the node on the network. The content of each byte tells whether the node

is a Master or Slave (multiple PROFIBUS Masters may co-exist on the same

physical network).

This acyclic message can be sent in all operation modes (STOP, CLEAR, and

OPERATE), however the gateway must be initialized properly.

MNETDPV1_MAILVAR_GetLiveList Variables - Quantum

This variable structure is the one to use with your control and sequencing logic

when you want to request a list of PROFIBUS network nodes (bus subscribers).
