By default, the Allen­Bradley Communications enabler supports a combination of 100 devices and unsolicited data messages. If the total number of devices and unsolicited data messages exceeds this number, you must define an additional logical ABI_MAXDEF in the log_names.cfg file in order to specify the number of definitions required for your installation.

The following entry would increase the maximum definitions to a value of 300.
