Function Blocks

3.2.32 DIE_ - Digital Input - Ethernet (V3.0)

DIE_ function blocks are available when the
optional Ethernet communication board
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.
The MB REG parameter identifies the location of the digital data in the source device. The REG TYP parameter
enables reading of Holding Registers (Modbus Function Code 03) or Input Registers (Modbus Function Code 04).
Both are treated the same in most Modbus devices but the Input type is the most common usage. The use of DOE
blocks in other Siemens MOORE controllers as the input source is defined by using the Modbus Registers from the
table below. The UD RATE parameter configures the rate at which the block will request data. The P2P setting
will update the data at the rate set by the P2P RATE parameter in the ETHERNET block. The Ct setting will update
the data at the cycle time of the controller.
Output QS indicates the quality of the received data and will go high (1) when the data is bad. This is normally
associated with failure to receive data due to a communication failure or a misconfiguration of the source.
