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