The Second type of Configuration consist of 16 byte Input
With this type of Configuration it is possible exchange with only 16 the same data of the precedent
Configuration and in addition there are the values of the Totalizers positive or negative.
With the setting of a control byte, in the configuration string of the file GSD,it is possible to set the Data
Type of information returned by Input data.
The control byte is the third byte of the Configuration string (see below).
It is also possible to change the Data Type with a Class 1 and Class 2 Master and the relative Acyclic Slot
and Acyclic Index, during data exchange.
For details Acyclic Service see the relative section in this document.
The reference to the Configuration string in the GSD file is:
------------------------------------------------------------
Module = "16 Byte Input" 0x41,0x0F,0x00
2
EndModule
------------------------------------------------------------
The settings in the GSD file for to use this Configuration is:
-----------------------------------------
SlotDefinition
Slot(1) = "Process Data" 2
EndSlotDefinition
-----------------------------------------
The Configuration correspond to 16 bytes Input and the last byte indicate the Data Type selected .
Modifing the last byte in the GSD file it is possible to set the type of the Flow rate and the type of
Totalizers:
With the Configuration 0x41,0x0F,0x00 the Flow rate is in % ( 4 byte )
totalizers positive ( 4 byte )
partial totalizers positive ( 4 byte )
process flags ( 2 byte )
dynamic variations ( 1 byte )
the Data Type = 0 ( 1 byte )
-----------------------------------------------------------
Number of Input byte exchanged ( 16 byte )
With the Configuration 0x41,0x0F,0x01 the Flow rate is in % ( 4 byte )
totalizers negative ( 4 byte )
partial
totalizers negative ( 4 byte )
process flags ( 2 byte )
dynamic variations ( 1 byte )
the Data Type = 1 ( 1 byte )
-----------------------------------------------------------
Number of Input byte exchanged ( 16 byte )
Whit the Configuration 0x41,0x0F,0x02 the Flow rate is in tecnical unit ( 4 byte )
totalizers positive ( 4 byte )
partial totalizers positive ( 4 byte )
process flags ( 2 byte )
dynamic variations ( 1 byte )
