DOS_ function blocks, in firmware 1.30 and higher, transmit up
to 16 on/off signals received from a controller block
interconnection to a remote node on the LonWorks network as a
single 16-bit word value. A maximum of 6 DOS blocks can be
used, up to the limit of nodes allowed on the Lon network or the
memory limit of the controller. Each use of the block will be
assigned a unique station wide ID (e.g. DOS01). The transmitted
value is of type SNVT_state and can be bound to a network
variable in a remote node that can receive a network variable of
this type. These blocks will be available when the LonWorks
option board is installed in a 352P, 353, or 354N controller.
Each function block input has a mode associated with it. The
mode can be either NORMAL or FORCED. When using a PC
capable of sending LIL or Modbus commands, the mode can be
changed and the forced state can be assigned a high (1) or low (0)
value. The values accessible over the network are the two switch
inputs (N and F) and the position of the SPDT switch illustrated in
the block diagram. A mode of ‘0’ is Normal and ‘1’ is Forced.
The function block also has a quality status associated with it.
This status will go high (1) when the block determines it has lost
output communication with the Lon node bound to that input. DOUT_ function blocks are used to turn on remote
devices powered from an external source. The negative
terminal of the external power source must be connected to
station common. The transistor switch will turn on when
the block input S is high (1) and will turn off when low
(0). Two digital output function blocks are available on the
Controller Board.DTM_ function blocks provide shift registers to hold the
analog input signal A for a period of time and shift it from
register to register to provide an overall delay between
input and output as configured in parameter DEADTIME.
Input AT can be used to adapt the DEADTIME to an
external signal. The actual shift register used as the block
output will equal the whole value of input AT (e.g. 0.184 =
register 0, 1.897 = register 1).
Output MA will provide the moving average of register 0
to the output register divided by the number of registers
[e.g. output register = 50, MA = (R0+R1+R2+......+R50)/51].
Input E asserted high (1) will enable the operation of the DTM block. When this input is not configured, it will be
set high. A low (0) input will cause all registers and the outputs to equal the input A.
POWER UP - During a warm or cold start, all outputs will be initialized at 0 and all registers will be initialized to
the value of the input on the first scan.
