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, 12 is
specified as the beginning word for writing in a CPM1 PC, and five words of data
are specified, then 16 will become the last word for writing data, and the com-
mand will not be executed because AR 16 is beyond the writable range.
Searches for the first instance of a timer or counter instruction (TIM, TIMH(15),
TIML(––), TMHH(––), CNT, or CNTR(12)) with the specified TC number in the
user's program and reads the PV, which is 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.
