23 SUB_ADDR_IN_DATABLOCK 1 + 4 Select free UDP connection.
The remote node is entered in the job
header of the job buffer by the user
program when it calls AG_SEND. This
allows any node on Ethernet/LAN/WAN
to be reached.
Possible values:
1 = free UDP connection.
0 = otherwise
The parameter is practical only for a
UDP connection.

24 SUB_NTP_SERVER 4 + 4 The sub-block defines an NTP server
from which the CP can obtain its time
via the NTP protocol.
For the situation when one or more
NTP servers are not obtainable, up to 4
sub-blocks of ID 24 can be defined.
The sub-blocks of ID 24 may only be
installed in the system parameter block
type 0 / ID 0 (see Section 6.4).
