Internal Bits of CQM1-CPU44-E

• Range Comparison Result

Each bit of the CQM1-CPU44-E CPU Unit’s words AR 05 and AR

06 turns ON only when the comparison range coincides with the

angle of E6C3-AG5C. If it does not coincide, the bit turns (remains)

OFF.

• Present Value Read

The gray code signals of the E6C3-AG5C are automatically con-

verted into BCD or 360° code signals and read through the CQM1-

CPU44-E CPU Unit’s words AR 232 and AR 234. The present

value can be used for ladder programs.
