7.2.1.4. Error external output

This function outputs the detected error number to the external party through the serial port.

n Serial output

Use the serial port (RS232C) to output ASCII code to the external device.

Output formats are

1st byte : “$”

2~6th byte : “ERROR”

7th byte:“ “ (Blank)

8~11th byte : Error number

12th byte : CR

13th byte : LF

Ex) For error 0101 (E0101)

n Number pre-designation output

Output of pre-designated number outputs the error/warning number of the signal assigned『[F2]: System』 → 『2: Control parameter』 → 『2: Input/output signal setting』 → 『4: Output signal assign』.

Table 7‑1Output of signal assignment by assigned signal

Assigned signal name	Whether to assign and how many
Assigned signal name	8 bit	16 bit
Error/Warning output selection	○: 1	×
Error/Warning output STRB	○: 1	×
Error/Warning output Bit	○: 8	○: 16
System error, operation error	○: 1	○: 1
Warning generated	○: 1	○: 1

l If the warning generation output signal is ‘0’, it is an error number. If it is ‘1’, it is a warning number.

l When a warning is generated, system error signals as well as operation error signals will not be turned on.

① 8 bit – Convert the error/warning number to a binary number and divide the bottom 8 bit and top 8 bit for output. The signal to classify the bottom and top data is the error/warning output selection signal. The strobe function that decides the data check timing is the error output STRB signal.

Ex) In case of E0101, the timing as well,

(10110 = 006516 = 0000 0000 0110 01012)

② 16 bit – Convert the error number into 2digit number and output the 16 bit data.

The strobe signal that decides the data check timing

- System error Þ Overall error

- Operating error ÞOperational error or above.

Ex) In case of E0101, the time as well (System error)
