■ Command format
■ Response format (When the command is executed normally, the response
includes the end code "00".)
Forced update of I/O relay/internal utility relay (WR)
This command forces updating (overwriting) of values of the I/O relays/internal utility
relays starting from the specified ch. within the specified range.
■ Command format
■ Response format (When the command is executed normally, the response
includes the end code "00".)
Note 1: The KV-300 CPU has 10 input addresses, 0000 to 0009. Therefore, when
data is written to 0000 ch, the KV-300 CPU ignores data written to input relays 0010
to 0015. Data cannot be written to addresses 0002 to 0004, or to addresses 0070 or
higher.
Note 2: Data cannot be written across special utility relays.
Update temporary data memory address (WH)
This command updates the temporary data memory addresses starting from the
specified TM no. within the specified range.
