MsgObjLAN1, Helper for LAN1
MsgObjLAN1.Frame
2 0..1 RW
EXTENDED REGISTER GROUPS
Indicate the frame type that this message object should
use.
0 = Standard, 11-bit Ids.
1 = Extended, 29-bit Ids.
Can only be used when LANx.LowProt equals
2
indicating that CAN specification 2.0 part B is supported.
Note. A descriptor that is programmed to receive
’Extended’ frames will not receive ’Standard’ frames nor will
a message programmed to receive ’Standard’ frames
receive ’Extended’ frames. (It is possible, if all units on the
net follow CAN specification 2.0, to mix ’Standard’ and
’Extended’ frames on the same net).
MsgObjLAN1.DataLen 3 0..8 RW
The data length for this message object. Normally it is most
efficient to use 8 bytes of data. It is not necessary to read
or write all bytes to an object before using it.
MsgObjLAN1.Vector 4 1..Max. line of PL2
program lines

RW
Action vector on a reception/transmission of the ID
specified.
Specify a line # where to execute code when a
reception or a transmission of an object with the
MsgObjLAN1.ID occurs.
MsgObjLAN1.Status 5 0..3 (when read)
1..12 (when written)
isrLan:
RW
This member has valid data after a GetObjLAN1
instruction has been executed.
On read, indicates the status of the descriptor. On write,
the value written is the that is to transmit a frame as
a response to a remote frame.
0 = Undefined
1 = The descriptor has been Transmitted.
2 = A remote frame has been received with this ID.
3 = The descriptor has been Received.
Usually used in a PL-code interrupt service routine for a
particular message object.
Example:
MsgObjLAN1.id = 400 MsgObjLAN1.type = 3
; Tx, with semi automatic remote frame
response
MsgObjLAN1.frame = 0
MsgObjLAN1.DataLen = 4
MsgObjLAN1.Vector = @isrLan
setObjLAN1 5 or lan1.mask, 16
; Enable interrupt
.. other initialization
;Message object 5 interrupt service routine
GetObjLAN1 5
; Get descriptor content
