5.1.2.4 Data Tag
The data tag specifies the type of internal resource of information needed to be ac-
cessed on the amplifier. The data associated with certain tags is read only. Therefore,
only the “Get” command byte would be associated with these data tags. The data tag
byte values are given in Table 5-2.
5.1.2.5 Error Status / Data Address
This byte is a tag extension byte and specifies the first data element of the tagged
data. If the Data Length is more than 1 byte, then all subsequent data fields must be
accessed starting from the specified address. For example, if the requester wants to
access the amplifier’s unique network address, it should set data tag 0 (Systems set-
tings tag) and data address 8 (see Systems Settings Details table). If the following
Data Length field is more than one (1), then all subsequent Settings will be accessed
after the Unique Network Address. When the Response Frame Data Address is omit-
ted, this byte position is replaced with the Error Status fields. The various error codes
are given in Table 5-3. Note that the Request and Response frames are different.
