(2) 7-Segment LED Status (02F3H - 0312H: 32 words)
02F3H-0312H in the acknowledgement area are used for the 7-segment LED status. The 7-
segment LED status shows the DN211 status, network status, and status of the slave devices the
DN211 manages. It corresponds with the error code indication on the front panel of the of DN211
(some of the statuses are not displayed on Table 6. 2 and Table 6.3). "NA = ¨ " in Table 6.11
shows a node address.

Table 6.12 7-Segment LED Status Code
Module status code Description
70 (46H ) DN211 is encountering trouble at duplicated node address checking.
72 (48H ) DN211 cannot communicate with slave devices.
73 ( 49H )
The vendor ID, product type, or product code of a slave device differ from
those in the scan list of the DN211.
75 ( 4BH ) No slave device is found on the network.
No slave device is registered in the scan list.
76 ( 4CH ) DN211 has detected communication timeout since no response from
slave devices.
77 ( 4DH )
When the transmission size of a slave device differs from the size in the
scan list of DN211.
78 ( 4EH ) DN211 cannot start transmission with slave devices.
79 ( 4FH ) DN211 cannot send to slave devices.
80 ( 50H ) DN211's communication port is set to IDLE mode.
81 ( 51H ) DN211's communication port is set to FAULT mode.
82 ( 52H ) An error occurred due to fragmented transmission/reception data.
83 ( 53H ) Slave device initialization was refused.
84 ( 54H ) Slave device initialization is not completed.
85 ( 55H ) DN211 reception buffer has an overflow.
91 ( 5BH ) Busoff has occurred at DN211.
92 ( 5CH ) Network power of DN211 has trouble.
