Force Analog Output Update
Rate:
1. PLC sweep rate when used by
Force Analog Output
%AQ
command.
2. 250 microseconds when used as Digital Servo tuning output.
Notes: Since this is a single ended output, it should normally drive a user
device with a differential input to prevent common mode noise
problems. The positive differential input should be connected to
AOUT and the negative differential input to ACOM.
The
Select Analog Output Mode
%AQ command can be used to
select the source for the analog output. Refer to Chapter 5 for more
information.
