Command Response Method; Auto Output Method - Omron ZG User Manual

Communication Method
For serial interface-based communications, two communication methods are used;
"command response method" and "auto output method." The communication method can
be set and switched on the Controller.
Setting Serial Output Conditions p.98

Command response method

By this method, command processing is executed when a command is sent to the
Controller from an external device, and a response is returned to the external device from
the Controller, when command processing ends. An error response is returned when the
command sent from the external device is in error or when an error occurs during
command processing on the Controller.

Auto output method

By this method, measurement value data is automatically output to the connected
external device when the measurement values are applied after the input trigger is
detected. An error response is returned when error detection is erroneous or when an
error occurs during command processing on the Controller. Auto output is supported only
on the USB interface.
