Objects for the Transfer of Process Input data
Objects 1800
hex
to 181F
hex
define, together with objects 1A00
hex
to
1A1F
hex
, which input data are transferred. Additionally they define
the priority and the mode for the data transfer via TPDO.
Object 1800
hex
defines the priority, the minimum inhibit time, the
event timer and the transmission type for TPDO1. object 1A00
hex
defines the object-index, the sub-index and the data length for the
data which have to be transferred via TPDO1.
The object 1801hex together with object 1A01hex provides this
information accordingly for the TPDO2 etc.
The priority of the data is defined by the identifier/COB-ID.
The values are already entered by default for objects 1800hex to
1803hex and 1A00hex to 1A03hex .
A station with up to 64 digital inputs and 12 analog inputs therefore
transfers the process input data automatically via TPDOs.
Object 1800
hex
to 181F
hex
- Transmit PDO-Parameters
Objects 1800
hex
to 181F
hex
define the priority, the transmission type,
the inhibit time and the event timer for TPDO1 to TPDO32.
The priority is defined via the identifier/COB-ID (see "Identifier for
the Standard Objects", page 4-10) in sub-index 01
hex
. With the
highest bit of sub-index 01
hex
, the further content can be defined as
valid/invalid.
The transmission type is defined in sub-index 02
hex
. Possible trans-
mission type can be found in Table 39:.
The inhibit time is defined in sub-index 03
hex
.
The event timer is defined in sub-index 05
hex
.
Which data content is to be transferred with the RPDO1 to RPDO32
is defined with the objects 1A00hex to 1A1Fhex.
