Figure 6-21 The "Masks" box in the parameter assignment dialog of the "Binary send" channel type
Name:
Alarm mask
Range of
values:
Mask in hexadecimal format
Default:
00 (hex)
Explanation:
This alarm mask is not relevant for DNP3.
Name:
Send buffer principle mask
Range of
values:
Mask in hexadecimal format
Default:
00 (hex)
Explanation:
Changes in masked bits in the byte of the "Binary send" channel cause a
message transmission according to the send buffer principle. Changes from
0 to
1 and from 1 to 0 are evaluated.
The corresponding bits are masked in hexadecimal format.
Name:
Disable mask
Range of
values:
Mask in hexadecimal format
Default:
00 (hex)
Explanation:
Masked bits in the byte of the "Binary send" channel are ignored w
hen
changes are checked. This means that changes to the masked bits for this
channel do not trigger message transmission. A masked bit always has the
value 0 in the message.
The corresponding bits are masked in hexadecimal format.
The bits are masked as shown in the following example in which the hexadecimal value "A3"
is entered in the input box of the parameter assignment dialog. The bits with the value 1 are
masked; in other words bits no. 0, 1, 5 and 7 cause the relevant masking function in the
described masks.
