Outputting a band comparison result of double-precision real
number
EDZCP(P)
These instructions compare the band between the double-precision real number specified by lower limit value (s1) and the
double-precision real number specified by upper limit value (s2) with the double-precision real number in the device specified
by comparison data (s3). According to the comparison result (below, within zone, or above), (d), (d)+1, or (d)+2 is turned on.
■Execution condition
■Description, range, data type
• The RnCPU and RnENCPU with firmware version "17" or later support these instructions. (Use an engineering tool with version "1.020W" or later.)
