IDN8 Command Value Valid Time (t
3
)
The time at which the amplifier is allowed to access the new command values after the
MST.
In all cycle times above 500 µs this is the time at which the amplifier synchronizes itself.
At 500 µs it is synchronized to 450 µs by default, for all other values please refer to the
ASCII documentation for “BUSP1".
The “Command Value Valid Time” is limited by the “MDT Transmission Starting Time”
(IDN89), the “Command Value Processing Time” (IDN90) and the CCT (IDN2) according
to this equation.
IDN89 + MDT Transmission Time + IDN90 < IDN8

IDN9 Position of Data Record in MDT
The offset of the amplifier’s data record within the MDT. The offset is measured in bytes
from the MDT’s address field. The data record position within the MDT must be down-
loaded from the master during CP2 and becomes active during CP3. The value must be
greater than zero and must be an odd number not exceeding 65531.

IDN10 Length of MDT
The length of the MDT’s data field, expressed in bytes. This length does not include the
MDT delimiters, address field, or cyclic redundancy check (CRC). The MDT length must
be downloaded from the master during CP2 and becomes active during CP3. The MDT
length must be an even number, and it must be greater than or equal to 4, but not
exceeding 65534.
