Communication Error Information - Mitsubishi Electric MELSEC IQ-R series Reference Manual

Communication error information

A data to specify the communication error information to be initialized.
The data is equivalent to the buffer memory '0H', '1H' of MELSEC-Q/L series C24.
Specify the value (16-bit integer) in bit unit. The communication error information and its corresponding bit are as follows.
Item
Communication error information (CH1)
Communication error information (CH2)
The communication error information to be initialized can be specified by turning the corresponding bit ON (1).
When the command is executed, the following corresponding bit of the buffer memory turns OFF (0).
"LED lighting status, communication error status" (Buffer memory 513 (201H), 514 (202H))
For MELSEC iQ-R series C24, specify '0'.
Setting method
■Data communication in ASCII code
Convert the numerical value to 4-digit ASCII code (hexadecimal), and send it from the upper digits.
■Data communication in binary code
*1
Send 2-byte numerical values from lower byte (L: bits 0 to 7).
*1 For C24, the additional code may be added. (Page 35 Additional code (10H))
Ex.
When initializing C/N, P/S, PRO, and SIO (bit 1 to 4) with MELSEC-Q/L series C24.
