The address range for P1 devices is from 0 to 96, with two exceptions:

  1. P1 BIMs use the address key ranging from 0 to 127 as the P1 address. Therefore, P1 BIMs can have an address range that extends beyond 96.
  2. P1 PXMs use their dip switch address configuration. Therefore, P1 PXMs have an address range between 0 and 31.

Regardless of the P1 device type, users should never use 99 or 255 as a P1 address.
