Data Link Status Flags
SR 238 to SR 245 contain the data link status for SYSMAC LINK/SYSMAC NET
Systems. The data structure depends on the system used to create the data link.

3-4-2 Remote I/O Systems
SR 25312 turns ON to indicate an error has occurred in Remote I/O Systems.
The ALM/ERR indicator will flash, but PC operation will continue. SR 251 con-
tains information on the source and type of error and AR 0014 and AR 0015 con-
tain information on the SYSMAC LINK status. The function of each bit is de-
scribed below. Refer to Optical and Wired Remote I/O System Manuals for de-
tails.

SR 25100 – Error Check Bit
If there are errors in more than one Remote I/O Unit, word SR 251 will contain
error information for only the first one. Data for the remaining Units will be stored
in memory and can be accessed by turning the Error Check bit ON and OFF. Be
sure to record data for the first error, which will be cleared when data for the next
error is displayed.

If the content of bits 12 through 15 is B, an error has occurred in a Remote I/O
Master or Slave Unit, and the content of bits 08 through 11 will indicate the unit
number, either 0 or 1, of the Master involved. In this case, bits 04 to 06 contain
the unit number of the Slave Rack involved.

the unit number of the Slave Rack involved.
If the content of bits 12 through 15 is a number from 0 to 31, an error has oc-
curred in an Optical I/O Unit or I/O Terminal. The number is the unit number of the
Optical I/O Unit or I/O Terminal involved, and bit 04 will be ON if the Unit is as-
signed leftmost word bits (08 through 15), and OFF if it is assigned rightmost
word bits (00 through 07).
