ControlLogix Connectivity Settings
Hostname
|
The Hostname value is the IP Address of the ControlLogix Ethernet module (1756-ENET) to route through to connect a ControlLogix processor. EthernetIP protocol on TCP port 44818 (0xAF12) is used to communicate to ControlLogix processors.
|
Communication Timeout
|
After sending a request to the ControlLogix processor, the Communication Timeout setting is the amount of time in mSec to wait for a response before treating it as a failure.
|
Browse Cache Timeout
|
When the data table layout is read from the ControlLogix processor, the Browse Cache Timeout value is the amount of time in mSec to cache the results.
|
Slot Number
|
The Slot Number value is the zero based ControlLogix chassis slot number of the ControlLogix processor to connect to.
|
Connection Path
|
The Connection Path value is used to define the route of the PLC-5 processor to connect to. Currently routing through the ControlLogix Ethernet Communication Interface Module (1756-ENET) to the ControlLogix Data Highway Plus-Remote I/O Communication Interface Module (1756-DHRIO) and on to a PLC-5 processor of the DH+ network is supported.
|
Concurrent Requests
|
The number of requests that Ignition will try to send to the device at the same time. Increasing this number can sometimes help with your request throughput, however increasing this too much can overwhelm the device and hurt your communications with the device.

More Information On Connection Path
The Connection Path format contains 4 numbers separated by commas. The first number is always 1 and tells the 1756-ENET module to route through the backplane. The second number is the slot number of the 1756-DHRIO module of the DH+ network the PLC-5 processor is connected to. The third number is the channel of the 1756-DHRIO module that the PLC-5 processor is connected to. Use 2 for channel A and 3 for channel B. The final and fourth number is the DH+ node number. This number is in octal and is the same as configured in the PLC-5 processor. See the ControlLogix Ethernet Communication interface Module User Manual for more information.
Connection Path Format: 1,<1756-DHRIO slot number>,<1756-DHRIO channel>,<DH+ node number>
The valid range for the 1756-DHRIO slot number is between 0 and 16 but depends on the chassis size.
The 1756-DHRIO channel is either 2 for channel A or 3 for channel B.
The DH+ node number range is from 00 to 77 octal.
