4 Message Communications
4-12
CJ-series User Defined CAN Unit Operation Manual for NJ-series CPU Unit (W517)
Note 1
On response code 0000, the unit configures the output message buffer identified with buffer
number with the following properties:
•
Extended identifier length (11-bit)
•
Identifier number
•
Send mode, (see
in Section 1)
•
Send cycle time (if the send mode is 2)
•
Big or little endian format, see
Each Output (Send) Buffer requires the following settings that are configured using the command code
2904.
•
the 29-bit identifier
•
the method of sending (SM1 = triggered, SM2 = on change or SM3 = cyclic)
•
the send cycle
•
the use of little endian or big endian
1103
No area type
Unit state = ST3 or ST4 and
the memory area is not avail-
able
Number of output buffers
exceeds the number of out-
put buffers configured by
message command 2902.
Increase the number of output
buffers with message com-
mand 2902 or select an out-
put buffer smaller than de
maximum of output buffers
configured by message com-
mand 2902.
1109
Mutual relation error
Unit state = ST4 or ST5 and
send mode = 2 and send
cycle = 0
Set the send cycle different
from zero or change the send
mode.
110C
Parameter error
Unit state = ST4 or ST5 and
one or more parameters are
not in range
Correct the parameters.
2201
Not executable in current
mode
Unit state = ST3
Nothing configured. Perform
message command 2902
before executing this com-
mand
220F
The specified service is
being executed
Unit state = ST5 and send
mode “changed” and the mes-
sage is being sent
Disable communications,
reconfigure the buffer and
enable communications.
