Host Link Commands Section 6-3
6-3-17 SV READ 3 –– R% (CQM1 Only)
Reads the constant SV or the word address where the SV is stored. The SV
that is read is a 4-digit decimal number (BCD) written in the second word of
the TIM, TIMH(15), CNT, or CNTR(12) instruction at the specified program
address in the user’s program. With this command, program addresses can
be specified for a program of 10K or more.
Command Format
Response Format An end code of 00 indicates normal completion.
Parameters Name, TC Number (Command)
Specify the name of the instruction for reading the SV in “Name.” Make this
setting in 4 characters. In “TC number,” specify the timer/counter number used
by the instruction.
Operand, SV (Response)
The name that indicates the SV classification is returned to “Operand,” and
either the word address where the SV is stored or the constant SV is returned
to “SV.”
Note The instruction name specified under “Name” must be in four characters. Fill
any gaps with spaces to make a total of four characters.
