Setting Rotary Switches
Set the location of the Ethernet RIO drop on the network with the rotary switches on the front of the BM•CRA312•0 X80 EIO adapter module before you apply power to the module and before you download the application:
The values you set are applied during a power cycle. If you change the switch settings after the module has powered up, the Mod Status LED is activated and a mismatch message is logged in the module diagnostic.
Because new values on the rotary switches are implemented only at the next power cycle, we recommend that you set the value before starting the module. (Valid values: 00 ... 159)
The values on the rotary switches combine with the device prefix (for example, BMECRA_xxx or BMXCRA_xxx) to create the device name (where xxx represents the value of the rotary switches). The preceding figure shows the Tens switch set to 0 and the Ones switch set to 01, for a device name of BMECRA_001.
NOTE:
The rotary switches can be manipulated with a small flat-tipped screwdriver.
NOTE: Use only the small, plastic screwdriver that ships with the module to change the switch position.No software is required to configure or enable the rotary switches.
Do not use the Stored and Clear IP settings on the Ones rotary switch. (The functionality of these settings does not apply to RIO installations.)

RISK OF UNINTENDED OPERATION Use only the small, plastic screwdriver that ships with
the module to change the rotary switch position. Using a metal screwdriver
can damage the switch, rendering it inoperable. Failure to follow these instructions can result in injury or equipment damage. | |
