3.2.39 DOD_ - Digital Output lev_Discrete
DOD_
function blocks transmit up to 16 on/off signals
received from a controller block interconnection to remote
nodes on the LonWorks network. A maximum of 6 DOD
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. DOD01). Each input transmitted is of type
SNVT_lev_disc and can be bound to network variables in
a single or multiple remote nodes that can receive network
variables of this type. These blocks will be available when
the LonWorks option board is installed in a 352P, 353, or
354N controller. The 0 NV NUM parameter enables the
number that the station has assigned to input 0 to be
viewed. All subsequent network variables are assigned
consecutively.
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 inputs (F and N)
and the position of the SPDT switch illustrated in the
block diagram. A mode of ‘0’ is Normal and ‘1’ is
Forced.
Each function block input also has a quality status associated
with it. This status will go high (1) when the block determines
it has lost communication with the Lon node bound to that
input. If any of the individual quality inputs are high, the
Quality Status block output will also be high.
