Error Code: Only For i-7540D’s COM3 (CAN port)
If the Error response function on the i-7540D module is set to be “Yes”(that
mean enable) via the i-7540D Utility during the configuration period, the i-7540D
will send the error code to the device of the host PC through the Ethernet port
10003 when the i-7540D produces an error message automatically during the
operation mode. The meanings of these error codes are given below:
Table 7-1: Error code table
Error
code
Description Possible causes & solutions
1 Invalid header The RS-232 command string header is not “t”,”T”,”e”,”E”.
2 Invalid length
The length of command string is invalid. For example:
—
Error: t0013112233
Right: t0013112233<CR>
3
Invalid CAN
identifier
The CAN identifier bits depend on CAN specification
CAN 2.0A: total 11 bits, 0x000 ~ 0x7FF
CAN 2.0B: total 29 bits, 0x00000000 ~ 0x1FFFFFFF
4
Invalid CAN
data length
The data byte of the CAN Message does not match the data
length of the CAN Message. For example:
—
Error: t001512345<CR>
— Right: t00150102030405<CR>
If the i-7540D CAN baud rate is not the same as the CAN baud rate on the
CAN network, the ER LED on the i-7540D will be flash with a constant frequency
and the TX LED will solid green because the i-7540D cannot send any CAN
messages to the CAN network. Therefore, users will need to read the i-7540D
status by using the command “99S” (in the section 4.5) to help users understand
what is going in the module. In general, the following errors could occur: CAN
media connection problem, terminal resistor problem, different baud rate
configuration with CAN network and so on.
