7 APPLICATION FUNCTIONS
(b) Setting example B
The routing parameters must be set for the request source 1), relay station
2), relay station 3), relay station 4), relay station 5), relay station 6), relay
station 7), and relay station 8).
In addition, there are two types of routing parameter settings; one is used
when sending data from the request source to the request destination
(when sending a request), and the other is used when returning from the
request destination to the request source (when sending a response).
Either one of them or both must be set for each station.

POINT
If a transient transmission (SEND, READ, SREAD, WRITE, SWRITE or REQ) was
terminated abnormally, the "Time" when an error was detected, "Abnormal
detection network number," and "Abnormal detection station number" can be
checked from the control data of the instruction used.
For detail on these instructions, refer to Section 7.4.5.
