Examples of Valid Ethernet Network Addresses

The sample networkdepicts a PLC network utilizing a CIMPLICITY computer using Allen-Bradley Communications to:

Communicate to various PLCs directly over Ethernet, through a PLC­5/250 and other bridge devices, and through a 1784-KTX card.

Communicate to various PLCs via a 1784-KTX card using Data Highway Plus protocol.

The network address for CIMPLICITY device configuration has following format :

Driver_name, Port_id, Station_number

The network address for each device in the sample Ethernet network is:

Device

Address

PLC­5/250

AB_ETH-1,AB:LOCAL,1

PLC­540E

AB_ETH-1,AB:LOCAL,2

PLC­5

AB_ETH-1, AB:PIGATEWAY/P:0/M:RM/C:2/E:1,31

 

Communication is via the Resource Manager in the 5/250 on channel 2

PLC­3

AB_ETH-1,AB:PIGATEWAY/P:1/M:KA/C:2/E:1,6

 

Communication is via the KA module in the 5/250 on channel 2

 

This example assumes that the pushwheel setting on the KA Module is 1.

PLC­2

AB_ETH-1,AB:PIGATEWAY/B:71/P:1/M:KA/C:2/E:1/KA,4

 

Communication is via the KA module in the 5/250 on channel 2, a 1785KA bridge, and a 1785KA module

The network address for each device in the sample Data Highway Plus network is.

Device

Address

PLC-5

AB_KT-1,AB:LOCAL,12

SLC-5/04

AB_KT-1,AB:LOCAL,17

SLC-5/05

AB_KT-1,AB:LOCAL,17

Note: When directly connected to the Data Highway Plus network via the 1784-KTX adapter, the driver name is AB_KT-1, the Port ID is AB:LOCAL, and the Station Number is the number assigned to the PLC.

Refer to the Device Configuration section of this document for information on the format of the network address.

Refer to the RSLinx Reference Manual for additional detailed information on offlink addressing.
