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. DIL_ function blocks are available when the optional LIL
communication board is installed. DIL block numbers are
assigned in sequence with each use, station wide. The block
allows the station to obtain a global word (GW) from another
station on the LIL.
The function block has 16 outputs, D0 through DF, which
represent the values of bits 0-F in the global word. 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 global data due to a LIL failure or a misconfiguration of
the source.
The received global word will also be re-transmitted by this station as a parameter 1 value in the configured channel
n. DIN_ function blocks can be used to sense a discrete
signal from an external source and provide a block output
representing the state of this signal. Blocks are available
on the Controller Board and on the Expander Board.
Function block names (IDs) and terminal designators are
listed in Section 8.4.
The block output is high (1) when the input is on and low
(0) when off.
Output QS indicates the quality status of the output signal
O1 and will be high (1) when the output is of bad quality.
Bad quality indicates any hardware failure of the input
converter.DINU_ blocks have multi-function capability:
? sensing a discrete input and providing a high (1) or low
(0) output representing the state of the input
? totalizing and scaling the count of input pulses
? converting the rate of input pulses to a scaled analog
