6.3.3 Execution Node Information
When you specify "3" for request information type at RAS information read request, the execution
information of the slave devices (module status, 7-segment LED status) can be read into the
acknowledgement area.

(1) Module Status (02D3H - 02F2H: 32 words)
02D3H-02F2H in the acknowledgement area are used for module status.
Module status indicates the operations in code that the DN211 is executing with slave devices and
the network. "NA = " in Table 6.9 shows a node address.

Table 6.10 Module Status Code
Module status code Description
0 ( 00H ) Normal status
1 ( 01H ) Not set to transmittable status enabled
2 ( 02H ) No data flows onto the transmission path
3 ( 03H ) Communication error occurred.
4 ( 04H ) The scan list differs from the actual slave composition.
5 ( 05H ) The network is encountering trouble.
6 ( 06H ) Abnormal network power is detected.
