STRING |
The communication path allows for connection routing across multiple backplanes. It uses a common format found in Logix controllers. It consists of pairs of values, each pair begins with either 1 (Backplane) or 2 (Ethernet), followed by a slot in the case of a backplane address, or if using Ethernet an ip address. e.g. [1,4,2,192.168.0.1,1,1] - Routes to the 4th slot in the first rack, which is a ethernet module, it then connects to the address 192.168.0.1, then finds the module in slot 1. |
||
|
INT |
Without using routing information the backplane defaults to 1. This is overridden if communicationPath is provided. |
||

INT |
The slot within the backplane the CPU is located. |

Individual Resource Address Format
Connection String
Logix has the following connection string format:-
logix:tcp://{ip-address}:{port}?{options}
An example connection string would look like:-
logix:tcp://127.0.0.1:502?communicationPath=[1,1]
Note the port and option fields are optional.
General Format
In general all Logix addresses have this format:
{address}:{data-type}[{array-size}]
If the array-size part is omitted, the size-default of 1 is assumed.
If the data-type part is omitted, the data type from the controller is used
The address format matches that found in the controller.
