Maestro Software Manual Ethernet/IP Communication
MAN-MASSW (Ver. Q)
11-15
Assembly objects can have one of following direction types:
• Consuming- an Assembly that consumes data from the network
• Producing- an Assembly that produces data on the network
• Configuration- an Assembly used to store configuration data that comes with
incoming Forward Open. It should be listed as Connection Configuration Instance in
the incoming Forward Open and not used for originating connections.
11.6.1 User interface to create communication objects
User interface described in section 11.5.2.1 User interface to create communication
objects of the Manual.
Assembly data size and type (Communication Format) must be identical for both
sides of the Ethernet/IP connection: the scanner (Rockwell device) and the adapter
(Maestro device).
11.6.2 Using syntax
Assembly object using syntax described in section 11.5.2.2 Using syntax of the
Manual.
The following Maestro program listing illustrates working with Assembly objects
and task synchronization via the operator until and global variables:
Listing 1.
int gEvent, gCons
//enter point of Maestro application
//TASK 1
function run()
global int gEvent
TRACE( "Start Task 1..." )
gEvent = 0
Task2.run()//run Task2
until( gEvent != 0 )//wait global variable
TRACE( "Task 1: Event %", gEvent )
prod.Param00=1//change produsing Assembly member value
end function
// Ethernet/IP event handler
function @eipevent(int event, int param1, int param2)
global int gEvent, gCons
switch( event )
case( 8 )
gEvent = param1
case( 9 )
gEvent = param1
end switch
gCons = cons.Param00;//read consuming Assembly member value
end function
//TASK 2
function run()
TRACE( "Start Task 2..." )
until( Task1.gEvent != 0 )//wait global variable
TRACE( "Task 2: Event %", Task1.gEvent )
prod.Param00=2//change produsing Assembly member value
end function
