Chapter 4 Using Programming Software in DH+ Applications
DH+ Program the controller in slot 9 of the remote chassis.
Go from DH+ to the local chassis.
Bridge to the remote chassis over ControlNet. Configure the DH+ driver.
Enter connection path: 0, 8#37, 1, 0, 2, 42, 1, 9
0 = DH+ port of the KT communication card in the workstation
8#37 = octal DH+ node of the 1756-DHRIO or 1756-DHRIOXT module in slot 9 of the local chassis
1 = backplane port of the 1756-DHRIO or 1756-DHRIOXT module in slot 9 of the local chassis
0 = slot number of the 1756-CNB module in the local chassis
2 = ControlNet port of the 1756-CNB module in slot 0 of the local chassis
42 = ControlNet node of the 1756-CNB module in slot 0 of the remote chassis
1 = backplane port of the 1756-CNB module in slot 0 of the remote chassis
9 = slot number of the controller in the remote chassis
Program the controller in slot 9 of the remote chassis.
Go from DH+ to the local chassis.
Bridge across DH+ to the remote controller. Configure the DH+ driver.
Enter connection path: 0, 8#37, 1, 2, 3, 8#24, 1, 9
0 = DH+ port of the KT communication card in the workstation
8#37 = octal DH+ node of the 1756-DHRIO or 1756-DHRIOXT module in slot 9 of the local chassis
1 = backplane port of the 1756-DHRIO or 1756-DHRIOXT module in slot 9 of the local chassis
2 = slot number of the other 1756-DHRIO or 1756-DHRIOXT module in the local chassis
3 = Channel B of the 1756-DHRIO or 1756-DHRIOXT module in slot 2 of the local chassis, configured for
DH+
8#24 = DH+ node of the 1756-DHRIO or 1756-DHRIOXT module in slot 2 of the remote chassis
1 = backplane port of the 1756-DHRIO or 1756-DHRIOXT module in slot 2 of the remote chassis
9 = slot number of the controller in the remote chassis
ControlNet
Ethernet
DH+ Use several network connections across different network
bridges:
• DF1 (connected to controller module
in local rack)
• ControlNet to the remote chassis
• Ethernet back to the local chassis
• DH+ back to the remote chassis
Configure the DF1 driver (to handle worst case performance)
Enter connection path: 1, 0, 2, 42, 1, 1, 2, 21.21.21.21, 1, 2, 2, 8#25, 1, 9
1 = backplane port of the ControlLogix controller in slot 6 of the local chassis
0 = slot number of the 1756-CNB module in the local chassis
2 = ControlNet port of the 1756-CNB module in slot 0 of the local chassis
42 = ControlNet node of the 1756-CNB module in slot 0 of the remote chassis
1 = backplane port of the 1756-CNB module in slot 0 of the remote chassis
1 = slot number of the 1756-ENET module in the remote chassis
2 = Ethernet port of the 1756-ENET module in slot 1 of the remote chassis
21.21.21.21 = IP address of the 1756-ENET module in slot 1 of the local chassis
1 = backplane port of the 1756-ENET module in slot 1 of the local chassis
2 = slot number of the 1756-DHRIO or 1756-DHRIOXT module in the local chassis
2 = Channel A of the 1756-DHRIO or 1756-DHRIOXT module in slot 2 of the local chassis,
configured for DH+
8#25 = DH+ node of the 1756-DHRIO or 1756-DHRIOXT module in slot 2 of the remote chassis
1 = backplane port of the 1756DHRIO or 1756-DHRIOXT module in slot 2 of the remote chassis
