The two control words (bits 0 to 15) and 2 (bits 16 to 31) give
commands and external information to the converter. A select
parameter is assigned to each control-word bit, e.g. bit 0 of parameter
P554. The select parameter specifies from which source(s) this control
bit can be influenced (= changed).
USS interface, from which control
word bits 0 to 15
(= control word 1)
are to be changed (source)

Note:
♦ e.g. 21xy:
The first digit (here 2) identifies the interface SST1 as source.
The second digit (here 1) indicates that it is the 1st word in the PZD
area of the telegram. "xy" (= 00 to 15) identifies the bit position.
Control word 1 is always transferred in the 1st word of the PZD area in
the USS protocol.
♦ The control word command "ON/OFF1" should be taken from bit 0 in
the 1st PZD word of SST1.
♦ The control word command "OFF2" should be taken from bit 1 in the
1st PZD word of SST1.
♦ The control word command "ACK" should be taken from bit 7 in the
1st PZD word of SST1.
