Memory Areas
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.
Error Information: CIO 1500 + 25 × (Unit No.) (See page 302.)
Polling Node Address, Startup Node Address: CIO 1500 + 25 × (Unit No.) + 1 (See page 302.)
Network Participation Status: CIO 1500 + 25 × (Unit No.) + 2, + 3 (See pages 193, 302.)
