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.
