4.3.3
Parameter setting request (DN611B)
1) Function
This request is used to set "DN611B parameter". This request can be issued only when DN611B is in standby
mode. After setting "DN611B parameter" and "Slave device parameter", set DN611B to the transmittable state
"Run mode" with "4.3.5 Operation mode control request". If the slave device parameter has already been set
in the non-volatile memory in DN611B, set only "DN611B parameter" and make DN611B run mode by
"Operation mode control request" (Own node parameter cannot be set in the non-volatile memory).

a) When REQ is TRUE, the module specified by CH, UNIT, or SLOT is requested to set its own node
parameters.
b) The contents of PARA_LOCAL are described in the next section.
c) After completion of the own-node parameter setting request processing, DONE is set to TRUE.
d) When the own-node parameter setting request processing does not complete for more than 2 seconds due
to an error, etc., ERR and DONE are set to TRUE.
e) Outputs the completion status to STATUS.
f) If REQ is FALSE, both DONE and ERR will be FALSE.
g) Once this function block is activated (REQ is set to TRUE), hold REQ TRUE until DONE is set to TRUE.
