Network Status Flags

Bits A20200 through A20207 are turned ON to indicate that the SEND(90), RECV(98), CMND(490) and

PMCR(260) instructions and background execution (CS1-H CPU Units only) can be executed for the corre-

sponding port, 0 through 7. 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(260).

Port 0 to 7 Response Codes

A203 through A210 contain the response codes for ports 0 through 7, respectively, following data communica-

tions using SEND(90), RECV(98), CMND(490), or PMCR.

CS-series CPU Bus Unit Initializing Flags

Bits A30200 through A30215 turn ON while the corresponding CS-series CPU Bus Units (Units #0 through

#15, respectively) are initializing.

CS-series CPU Bus Unit Setting Error Flag and Unit Number

Bit A40203 is turned ON when the CS-series CPU Bus Units actually installed differ from the Units registered

in the I/O table. The unit number of the CS-series CPU Bus Unit involved is written to word A427.

Bits A42700 through A42715 correspond to CS-series CPU Bus Units 0 through 15, respectively. When an

error occurs, the bit corresponding to the unit number of the CS-series CPU Bus Unit involved is turned ON.

CS-series 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-series CPU Bus Units. The unit number of the CS-series CPU Bus Unit involved is written to word A417.

CS-series CPU Bus Unit Numbers

Bits A41000 through A41015 correspond to CS-series 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-series CPU

Bus Units involved are turned ON.

CS-series CPU Bus Unit Duplication Error Flag

Bit A40113 is turned ON when two CS-series CPU Bus Units have been assigned the same unit number. The

duplicated unit number is indicated in A410.
