(a) Multiple-point E-CAM Data or no data
(b) 3-point E-CAM Data
Control Steps
:
Step 1: Set M80 to convert the 4-point E-CAM data (3-point data with an additional point 0) into binary
floating point format, and store the results in D0~D15.
Step 2: Set M81 to to write the data in D0~D15 into E-CAM chart-0 (K100).
Step 3: Set M82 to read the written data back into D100~D115 so as to confirm the data is correctly written
into E-CAM chart-0.
Step 4: Use Monitor Table to confirm the data read back in D100~D115. Data format (Radix) of D100~D115
should be set as floating point.
