Read status of counter/timer/high-speed counter comparator (RG)
This command reads the ON/OFF status of the counter/timer/high-speed counter
comparator starting from the specified no. within the specified range.
■ Command format
■ Response format (When the command is executed normally, the response
includes the end code "00".)
Note 1: The values of the counter/timer and high-speed counter comparator CTC
cannot be read with a same single command at once. Read the counter/timer and
CTC values individually.
Note 2: The station no. is indicated in decimal; the end code, in hexadecimal.
Read DM value (RD)
This command reads values of the data memory addresses starting from the
specified DM address within the specified range.
■ Command format
■ Response format (When the command is executed normally, the response
includes the end code "00".)
Read I/O relay/internal utility relay (RJ)
Reads values of the I/O relays/internal utility relays starting from the specified relay
ch. within the specified range.
Read start No.
