Appendix B
CPU Bus Unit Numbers
Bits A41000 through A41015 correspond to CPU Bus Units #0 through #15, respectively. When two CPU Bus
Units have the same unit number, the bits corresponding to the unit numbers of the CPU Bus Units involved are
turned ON.
Network Status Flags
Bits A50200 through A50207 are turned ON to indicate that ports #0 through #7, respectively, are enabled for
the SEND(192), RECV(193), and CMND(194). Bits A50208 through A50215 are turned ON to indicate that an
error has occurred in ports #0 through #7, respectively, during data communications using SEND(192),
RECV(193), or CMND(194).
A503 through A510 contain the completion codes for ports #0 through #7, respectively, following data commu-
nications using SEND(192), RECV(193), or CMND(194).
CIO Area: CPU Bus Unit Area
The CPU Bus Unit Area is allocated to CPU Bus Units according to the unit numbers assigned to them, as
shown below. Each Unit is allocated 25 words. The Controller Link Units use 22 of the words allocated to them.

Polling node address
Startup node address
Each node address is displayed in 2-digit BCD.
The numbers in the squares indicate node addresses.
The corresponding node participation status is as follows:
0: Not part of the network
1: Part of the network
