Component
Description
<signature>
The signature specifies whether the value is an input or an output
value, and how many words or bytes the value contains. The signa‐
ture syntax is as follows:
<Direction><Number><Unit>
<Direction>:
•
i: For an input value for the master
•
o: For an output value from the master to the device
<Unit>:
•
b: Bytes
•
w: Word
Nomenclature:
•
A byte is an 8-bit value.
•
A word is a 16-bit value.
•
Consistency means that all values within a module are updated simultaneously.
•
An input value is transmitted cyclically from the device to the master (PLC).
•
An output value is transmitted cyclically from the master (PLC) to the device.
•
A configuration value is only transmitted once from the master to the device when
the PROFIBUS device is switched on.
Relative address specification:
•
<Offset in Byte>
•
<Offset in Byte>.<Bit position within the entry> or
•
<Offset in Byte>.<Start bit position ... End bit position within an entry>.
