Parameters Write Data (Command)
Specify in order the contents of the number of words to be written to the AR area
in hexadecimal, starting with the specified beginning word.
Note If data is specified for writing which exceeds the allowable range, an error will be
generated and the writing operation will not be executed. If, for example, 26 is
specified as the beginning word for writing, and three words of data are speci-
fied, then 28 will become the last word for writing data, and the command will not
be executed because AR 28 is beyond the writeable range.
11-3-15 SV READ 1 –– R#
Searches for the first instance of a TIM, TIMH(15), CNT, CNTR(12), or TTIM(87)
instruction with the specified TC number in the user’s program and reads the PV,
which assumed to be set as a constant. The SV that is read is a 4-digit decimal
number (BCD). The program is searched from the beginning, and it may there-
fore take approximately 10 seconds to produce a response.

SV (Response)
The constant SV is returned.
Note 1. The instruction specified under “Name” must be in four characters. Fill any
gaps with spaces to make a total of four characters.
2. If the same instruction is used more than once in a program, only the first one
will be read.
3. Use this command only when it is definite that a constant SV has been set.
