6-5-16 AR AREA WRITE –– WJ
Writes data to the AR area, starting from the specified word. Writing is done
word by word.
Command Format
Response Format An end code of 00 indicates normal completion.
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
specified, then 28 will become the last word for writing data, and the com-
mand will not be executed because AR 28 is beyond the writable range.
6-5-17 SV READ 1 –– R#
Searches for the first instance of a TIM, TIMH(15), TTIM, CNT, and CNTR(12)
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, which
may take as much as 10 seconds to produce a response.
