The Add Control Unit <=> Processor Definitions dialog allows you to assign CUADD values to the connections of multiple control units in ascending order. You may choose an Offset (or step size) other than 1 to implement your own numbering schemes.

Processor Definitions
HCM displays this dialog when you establish the first CHPID connection of a control unit. Use this dialog to specify the connection attributes.
For control units that already have processor connections, HCM does not display this dialog. When adding more connections, the previously defined CUADD value is used for the new connection(s).
