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.

Bin04B_R
Channel "OutputByte_x"
Channel type: Binary receive
Bin04B_R theoretically allows receipt of up to 32 binary values in 4 channels each of 1 byte
(8 binary values per byte). The object occupies 32 indexes if all 4 channels are configured.
In the station, however, due to the control code "LATCH_ON" (see below) the object can
only be received 1 bit at a time. To receive binary information, the "Bin08X_R" object is
therefore recommended.
Taking control codes into account
Note
Interlock function (LATCH_ON) for receiving only 1 bit
With control codes sent from a master station in a message (DNP3 object group 12, variation
1), Bin04B_R only takes into account the interlock function LATCH_ON. If more than 1 bit is
set at the same time in the entire object, LATCH_ON only sets the bit with the highest index
in the object. All other bits of the object are set to zero.
LATCH_OFF is not supported by Bin04B_R. The bit set with LATCH_ON must be reset by
the user program of the CPU.
Bin08X_S
Channel "StatusBit_x"
Channel type: Data send
Bin08X_S allows sending of up to 8 binary values. The object contains 8 channels each for 1
bit.
The object occupies 8 indexes if all 8 channels are configured.
Each index is written with a separate message. The messages are sent independently of
other.
The object in a master station corresponds to the DNP3 object group 12 with the function
code "Direct Operate".
