Appendix C
Related Auxiliary Area Information
This appendix lists the functions for the SYSMAC LINK Unit in the Auxiliary Area of the CS-series CPU Units.
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.
