PDO

All analog channels (AO and AI) of the terminal are available 4-fold (alternatively!) in the process image for mapping/activation:

Fig.167: 1A50 PDO

Example AI Output Voltage:

• in 2 representations
• as REAL32-FloatingPoint PDO (to be used preferably, saves consideration of the FSV)(default)
• alternatively as INT16 (FSV_resp.range= x7FFF) for compatibility with any existing programs
• and 2 data sizes
• Default: value + status (default)
• Compact: value only

The PDO mapping can be used in the SyncManager, a TwinCAT Activate

and reload is necessary afterwards
