Chapter 17 Configure Peer-to-Peer Communication
Output System Signal
Using the output system Connection Control signal, the user program
can control how the peer-to-peer connection is setup.
Design the Logic for all Controllers
Design the logic for the controllers, considering the variables intended
for network exchange.
The following examples show part of the routines for controllers
Robot A and Robot B, respectively. To evaluate the state of the
OutRange signal in Robot B, use the same signal name (OutRange) as
an input for the logic of Robot B. OutRange is sent over the Ethernet
Connection Control Values
Value Setting Description
0x0000 Autoconnect After loss of peer-to-peer communication, the controller
tries to re-establish communication in the next CPU cycle.
This is the standard mode of operation.
0x0100 Toggle_Mode 0 These modes allow automatic connect with Disable after
loss of communication.
If Toggle_Mode is 0 and communication is lost
(Connection State = CLOSED), a connect is performed
only after Toggle_Mode is set to 1 by the user program.
If Toggle_Mode is 1 and communication is lost, a connect
is performed only after Toggle_Mode is set to 0 by the
user program.
0x0101 Toggle_Mode 1
0x8000 Disabled Peer-to-peer communication is disabled.
No attempt to connect.
IMPORTANT
If the P2PControl signal, in the illustration above, is set to
32768, peer-to-peer communication is disabled. If Connection
Control is not set by the application, the default is 0 and
Autoconnect is enabled.
