Network Status Flags
Bits A20200 through A20207 are turned ON to indicate that ports #0 through #7, respectively, are enabled for
the SEND(90), RECV(98), CMND(490) and PMCR. Bits A219200 through A219207 are turned ON to indicate
that an error has occurred in ports #0 through #7, respectively, during data communications using SEND(90),
RECV(98), CMND(490), or PMCR. Refer to page 189.
A203 through A210 contain the completion codes for ports #0 through #7, respectively, following data commu-
nications using SEND(90), RECV(98), CMND(490), or PMCR. Refer to page 189.
CS/CJ CPU Bus Unit Initializing Flags
Bits A30200 through A30215 turn ON while the corresponding CS/CJ CPU Bus Units (Units #0 through #15,
respectively) are initializing.
CS/CJ CPU Bus Unit Setting Error Flag and Unit Number
Bit A40203 is turned ON when the CS/CJ CPU Bus Units actually installed differ from the Units registered in
the I/O table. The unit number of the CS/CJ CPU Bus Unit involved is written to word A427.
Bits A42700 through A42715 correspond to CS/CJ CPU Bus Units #0 through #15, respectively. When a error
occurs, the bit corresponding to the unit number of the CS/CJ CPU Bus Unit involved is turned ON.
CS/CJ CPU Bus Unit Error Flag
Bit A40207 is turned ON when a parity error occurs during the transmission of data between the CPU Unit and
CS/CJ CPU Bus Units. The unit number of the CS/CJ CPU Bus Unit involved is written to word A417.
CS/CJ CPU Bus Unit Numbers
Bits A41000 through A41015 correspond to CS/CJ 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 CS/CJ CPU Bus
Units involved are turned ON.
