DAM_ function blocks compute the difference between
inputs A and B, amplify the difference signal, and sum the
resultant with an internal BIAS and an external signal at
input C. Unused inputs are set to 0.0.DID_ function blocks convert 16 on/off signals received from
a single or multiple nodes on the LonWorks network into 16
block outputs for use by other function blocks within the
controller. A maximum of 6 DID 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. DID02). Input connections are
established by ‘binding’ each output variable of type
SNVT_lev_disc (SNVT #22) in the remote node devices to
each network variable in the DID 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 the number that the station
has assigned to input 0. All subsequent network variables are
assigned consecutively.
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.
Each function block output 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. If
any of the individual quality outputs are high the Quality
Status block output will also be high.
DIE_ function blocks are available when the
optional Ethernet communication board10 is
installed in the controller. It enables the controller
to read digital data from other stations over the
Ethernet network.
Up to 32 DIE_ blocks are available. Blocks are
assigned in sequence, controller wide, with each
use. Digital data is On/Off data packed into a 16-bit
word. This data is fanned out to block outputs D0 –
DF.
The IP ADRES parameter is used to configure the
IP address of the source device. The MB ADRES
parameter allows a Modbus address to be
configured. When connecting to other Siemens
MOORE controllers, the Modbus address is set to 1.
In some cases, other devices may use a different
address or when going through a Modbus TCP/IP gateway a Modbus network may have multiple devices, each
having a unique address.
