FBM206輸出擴(kuò)充模塊
在固件1.30及更高版本中，DIS_功能塊將16-從LonWorks網(wǎng)絡(luò)上的單個節(jié)點(diǎn)接收的位字分為16個塊輸出，用于與其他功能塊互連在控制器內(nèi)。最多可使用6個DIS塊，最多限制Lon網(wǎng)絡(luò)或內(nèi)存上允許的節(jié)點(diǎn)數(shù)控制器的限制。塊的每次使用將分配一個唯一的全站ID（如DIS02）。輸入連接為：通過“綁定”SNVT_state類型的輸出變量建立（SNVT#83）到DIS中的網(wǎng)絡(luò)變量

DIS_ function blocks, in firmware 1.30 and higher, convert a 16-
bit word received from a single node on the LonWorks network
into 16 block outputs for interconnection to other function blocks
within the controller. A maximum of 6 DIS 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. DIS02). Input connections are
established by ‘binding’ the output variable of type SNVT_state
(SNVT #83) in the remote node to the network variable in the DIS
function block. 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 viewing the number that the
station has assigned to input 0.
Each function block output 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 output associated with
it. This status will go high (1) when the block determines it has lost communication with the Lon node DIV_ function blocks perform simple arithmetic division.
The output will be the quotient of the two configured
inputs N/D. The output will be limited to the maximum
real number and, if the divisor is 0.0, the output will go to
the maximum real number with the sign determined by the
numerator. If the numerator is 0.0, the output will be 0.0.
Any unconfigured inputs will be set equal to 1.0. DNC_ function blocks provide a single output pulse for a
pre-selected number of input pulses. The output will go
high (1) with a positive transition of the input P, edge
triggered, and will return to a low (0) output on the
succeeding positive transition. POWER UP - During a hot or a warm start, with PU LAST
set to YES, the block will retain the last count and continue at
the last input/output states. If set to NO, during a warm or a
cold start, the output and count will be initialized to 0.
