Access type Meaning
R Device type (always "0")
R Current error state
R List of errors that occurred (max. 4 entries)
RW COB ID for SYNC message together with the setting of whether
the PN/CAN LINK is a SYNC producer.
RW Interval for SYNC messages
R Device name as character string.
Default: "PN/CAN LINK Slave"; the entry can be edited, see Con-
figuring in the TIA Portal (Page 83), section "Setting communica-
tion parameters > Vendor device name"
R Hardware version as character string. Corresponds to the HW
version that can also be read out via PROFINET and IM0.
R Software version as character string. Corresponds to the SW
version that can also be read out via PROFINET and IM0, for
example, "V 1.0.0 [Build xxx]".
RW "Guarding Time" for the node guarding protocol
RW "Life Time Factor" for the node guarding protocol
RW COB ID for EMCY messages sent by the PN/CAN LINK
RW Field for "Receiver Heartbeat Time", that is the setting of which
CANopen nodes the PN/CAN LINK monitors via heartbeat.
RW "Heartbeat producer time" Interval at which the PN/CAN LINK
sends heartbeat messages.
R Identity Object, identifies the device
RW Determines the error behavior of the PN/CAN LINK. Only the
entry for "Communication errors" is implemented.
R SDO Server Channel
RW RX-PDO Communication parameters
RW RX-PDO Mapping parameters
RW TX-PDO Communication parameters
RW TX-PDO Mapping parameters
