■Subcommand
For C24 of MELSEC-Q/L series, 0 to 3 bits of subcommands are equivalent to the following functions of C24.
The settings in the table above is recommended, even though the initialization can be performed with the
values (0001H to 000FH) which combined ON/OFF arbitrarily.
• Bit 0: CH1 Error initialization request (YE) ON
• Bit 1: CH2 Error initialization request (YF) ON
• Bit 2: LED for CH1 OFF, communication error information initialization request (buffer memory address: 0H)
ON
• Bit 3: LED for CH2 OFF, communication error information initialization request (buffer memory address: 1H)
ON
■Communication error information
Specify the items in "LED lighting status, communication error status" to be initialized. (Page 172 Communication error
information)
For MELSEC iQ-R series C24, specify '0'.
Communication example
Perform the following operations for CH1 interface of QJ71C24N-R2.
• ERR LED: OFF
• Input signal XE "Error occurrence": OFF
• Buffer memory 513 (201H) "LED lighting status, communication error status": Initialized (all items are OFF)
• Error code of buffer memory: Initialized (clear)
