4.6.4 Parameter Setting Request (slave device)
(1) The Function
This request is used for setting "slave devices parameters" in the DN211. The request can be
issued only when the DN211 is in standby mode.
Up to 10 salve devices can be set per parameter setting request.
As "slave devices parameters" setting is stored in the non-volatile memory of the DN211, no
additional setting is required when switching ON the power as long as the current slave devices
configuration is unchanged. When the slave devices parameters in the non-volatile memory are
identical with the slave devices parameters newly requested, no writing is executed into the non-
volatile memory.
When the slave devices configuration is changed, delete the slave devices parameters before
registering new slave devices parameters.
Up to 300 times of slave devices parameters setting are available in the non-volatile
memory of the DN211.
