Parameters
5.10.10.1.23 Basic COB ID for PDO reading results
Basic COB ID for PDO reading results
parameter defines the CAN identifier for the first
transmit process data object (TPDO) used to transmit the reading result.
When transmitting the reading results with process data objects (PDOs), the reading result
is distributed to several PDOs sent in sequence and sent to the PLC. The identifier for the
first PDO must be configured; subsequent PDOs have continuous identifiers.
5.10.10.1.24 Transmission type
The processing and triggering procedures for process data objects (PDOs) are configured
via the
parameter. The CANopen parameter defines the processing and
triggering time in relation to the SYNC object. The SYNC object is for synchronizing the CAN
nodes in the CAN bus and, together with the TIME STAMP object, ensures that the time is
uniform consistent across the network. The parameter must be entered in accordance with
the CANopen standard.
0xFE example: The device processes and transmits PDOs as soon as new data as available.
There are three different transfer types:
• A
SYNCHRONOUS
: PDOs bear no reference to the SYNC object. PDOs are processed as soon
as they have been received and sent immediately after they have been triggered. The trigger
can be controlled by an event or a send request.
• S
YNCHRONOUS
: PDOs are processed with temporal reference to the SYNC object. It is pos-
sible to set the number of SYNC objects before processing takes place.
• A
CYCLIC
SYNCHRONOUS
: PDOs are received with no reference to the SYNC object but are not
processed until after the next SYNC object. The PDO is triggered by an event with no refe-
rence to the SYNC object but is not transmitted until after the next SYNC object.
5.10.10.1.25 Inhibit time
The
parameter defines an interval in ms that must lie between the repeated
transmission of process data objects (PDOs).
5.10.10.1.26 Number of PDOs
The
parameter is used to determine the number of process data objects
(PDOs) that transmit the reading result.
When transmitting reading results with PDOs, the reading result data is distributed to seve-
ral PDOs. The PDOs are transmitted in sequence. The configured reading result is restricted
to 50 characters for this type of transmission.
5.10.10.1.27 Enable diagnosis output
parameter is activated, the device's reading diagnosis data
is monitored by the control via the CANopen interface. The reading device initiates moni-
toring via process data objects (PDOs). The device sends a PDO with identifier 0x180 and
CAN node to indicate that the control should load an entry.
