Addressing Modes
There are three addressing modes which are used for sending and
receiving data/commands from the PLC to the gun control nodes.
Broadcast Messages
See Broadcast Messages from the PLC section on Page 19 for a list of all
broadcast messages.
S Send messages from the PLC to all the gun control nodes
S Assigned top priority
S Examples include Gun Trigger or Lockout
Multicast Messages
See Multicast Messages from the PLC section on Page 20 for more
information on multicast messages.
S Send commands and data from the PLC group of gun control nodes
associated with a single gun
S At this time, multicast addressing only applies to Change Preset
Messages
NOTE: By default, each physical gun in a system also belongs to a
multicast group address (which is equal to the physical gun number). Since
each physical gun is connected to two gun control nodes (one for KV control
and another for Flow control), it is convenient to have the ability to send
certain messages to a given physical gun’s KV node/Flow node pair.
Unicast Messages
See Unicast Messages from the PLC section on Page 20.
S Sends commands and data from the PLC to an individual gun control
node (most commonly Set Preset Message)
S Send messages from the gun control nodes to the PLC (includes Gun
Monitor Message and System Status Message)
