1F98-06 NMT_CycleTiming_REC.AsndMaxLatency_U32
[Unsigned32, const]
It provides the maximum time in nanoseconds (ns), that is required by the CN to
respond to SoA.
The value is set up by the device firmware during system initialisation.
Default = 1000 (min. = 0, max. = 4294967295)
1F98-07 NMT_CycleTiming_REC.MultiplCycleCnt_U8
[Unsigned8, rw]
This sub-Index describes the length of the multiplexed cycle in multiples of the
POWERLINK cycle.
The value is upper limited by the MN’s device description entry
D_NMT_MNMultiplCycMax_U8
. It is equal in all nodes of the segment.
1F98-07 NMT_CycleTiming_REC.MultiplCycleCnt_U8
no support of multiplexed cycle on the network.
Default = 0 (min. = 0, max. = 255)
1F98-08 NMT_CycleTiming_REC.AsyncMTU_U16
[Unsigned16, rw]
This sub-Index describes the maximum asynchronous frame size expressed in
bytes. The value applies to Asnd frames as well as to UDP/IP and other legacy
Ethernet type frames. For this reason the value describes the length of the
complete Ethernet frame minus 14 bytes Ethernet header and 4 bytes checksum.
It
is
upper
limited
by
the
NMT_InterfaceGroup_0h_REC.InterfaceMtu_U16
segment. This limit is 18 bytes less than the minimum
InterfaceMTU_U16
value
provided by any node in the segment.
AsyncMTU_U16
can grow up to
C_DLL_MAX_ASYNC_MTU.
AsyncMTU_U16 is equal in all nodes of the segment.
This sub-Index is valid in all NMT states.
Default = 300 (min. = 300, max. = 1500)
1F99 NMT_CNBasicEthernetTimeout_U32
[Unsigned32, rw]
It provides the time expressed in microseconds (µs) to be applied before
changing from
state.
Please note that MN and CN startup timing has to be well balanced. System
power up sequence has to be considered.
Value “0” means that the state never changes to
If other than “0”, the value shall be greater than
To avoid erroneous change over to
1F99 NMT_CNBasicEthernetTimeout_U32
NMT_BootTime_REC.MNWaitNotAct_U32
of the MN.
Default = 5000000 (min. = 0, max. = 4294967295)
