Converting 32-bit binary data to Gray code
DGRY(P)(_U)
These instructions convert the 32-bit binary data in the device specified by (s) to 32-bit binary gray code data, and store the
converted data in the device specified by (d).
■Descriptions, ranges, and data types
■Applicable devices
• These instructions convert the 32-bit binary data in the device specified by (s) to 32-bit binary gray code data, and store the
converted data in the device specified by (d).
The data conversion speed depends on the scan time of the CPU module.
There is no operation error.
