EMS Dr. Thomas Wünsche
CG-ARM7/D/ECAN/CAN Gateway
The routing settings contain the filtering and mapping rules for a
single identifier or a range of identifiers. Only specified identifier or
ranges of identifiers are transmitted and, if existend, a mapping rule
is applied. All incoming messages with identifiers to which no rule
applies are ignored (defined programming identifiers excepted).
Additionally the frame format must be set within the filtering rule.
On the left side of the assignment there are three parameters:
[inff] fil channel [outff] = ...
inff: Defines the frame format to be accepted for incoming
messages. If inff is set to 's' standard frame format is specified.
When set to 'x' extended frame format is specified.
channel: Defines the number of the CAN channel to which the rule is
applied for incoming messages; channel may be set to 1 or 2.
outff: Defines the frame format for outgoing messages. If outff is set
to 's' standard frame format is specified. When set to 'x' extended
frame format is specified.
On the right side of the assignment up to three parameters specify
the identifier of the outgoing CAN message.
... = sid [- eid] [: mid]
sid: Defines the identifier the filtering rule is applied to. If a range of
identifiers is defined, sid is the start identifier. If the prefix 'x' is added
before the value the identifier is interpreted as a hexadecimal
number.
eid: Defines the end identifier for a range of identifiers. If only a
single identifier is to be specified this value may be missing. If the
prefix 'x' is added before the value the identifier is interpreted as a
hexadecimal number.
mid: Defines the mapping identifier. This value defines to which start
identifier a single or a range of identifiers is mapped. If no mapping
is needed, this value may be missing. If the prefix 'x' is added before
the value the identifier is interpreted as a hexadecimal number.
