dress translation (e.g. via a table). The default value of the Address
mask is 0xFFFF, hence the full 16-bit value is used by default.
Example:
The Address mode is set to Binary (2B LSB first), the Address mask is
set to 7FF0 and the Address position is set to 2. The SCADA message
starts with bytes (in hex) 02 DA 92 C3 .. The 2-byte address is read as
0x92DA (note the LSB came first in the message), Then 0x7FF0 mask
is applied and the resulting value 0x12D0 (0x92DA & 0x7FF0) is used
as the input for the translation.
• Poll response control
List box: On, Off
Default = On
On – The Master accepts only one response per request and it must
come from the the specific remote to which the request was sent. All
other packets are discarded. This applies to the Master–Slave commu-
nication scheme.
Note: It may happen, that a response from a Slave (No.1) is delivered
after the respective timeout expired and the Master generates the re-
quest for the next Slave (No.2) in the meantime. In such a case the
delayed response from No.1 would have been considered as the re-
sponse from No.2. When Poll response control is On, the delayed re-
sponse from the Slave No.1 is discarded and the Master stays ready
for the response from No.2.
Off – The Master does not check packets incoming from the mobile
network - all packets are passed to the application. That allows e.g.
spontaneous packets to be generated at remote sites. This mode is
suitable for the Master–Master communication scheme or a combination
of the UNI and ASYNC LINK protocols.
