When the check box is selected (true), the device can subscribe to a DHCP server service. NOTE: For certain devices,
it is selected by default and read-only (for example, CRA adapter modules).

Name of the device and its interface that provides the DHCP server services. Select a value from the list of devices and their interface that exist in the system project and feature a DHCP server service, whether it is enabled or not. NOTE: For certain devices,
the attribute value is predefined and read-only (for example, CRA adapter modules).

Enter the appropriate value depending on the setting that you have selected for PAC. . The software accepts only unique identifiers for a givenFor certain modules the software accepts only values that comply with module-specific format requirements. Refer to the manual of the module for details. For the following modules, the identifier must be in the format [DHCP Prefix][Controller]_[Slot]_[Part Number] where:

When a device is identified by MAC address, the attribute is read-only and the value provided by the attribute. The attribute cannot be left blank when is selected.NOTE: For PMEPXM0100 modules and TeSys devices,
the value must not exceed 16 characters.
NOTE: For
certain devices, the attribute is predefined and read-only.
NOTE:
For CRA adapter modules the device name includes a 3-digit number (for example, by default, 001 in PCRA_001_0 for a BMECRA31310 adapter module located in drop 1). The initial value of the 3 digits is based on the configuration of their Device Name in Control Expert Editor when you add the drop. Thereafter, you can only edit the 3 digits by using the attribute. Verify that the setting of the rotary switches on the physical CRA adapter module always matches these 3 digits. The first two digits represent the Tens and the third digit the Ones rotary switch. This 3-digit number also appears after the name of the drop containing the CRA adapter module. |
