Set verbose/response mode
24
This command controls both verbose responses/messages and tagged (labeled) responses.
Verbose mode is a communication mode in which the device responds with more information than it usually would. For
example, the MLC can send out a notice of a change in some setting without receiving a query via your PC. That change
could have been a result of an internal process (a scheduled script execution), a selection made using a touchpanel or
keypad, a change made using GV or the embedded web pages of the device, or input (a voltage or resistance change at a
port) from a connected sensor or switch. That is an example of a verbose (wordy) relationship between the control processor
and a connected device.
•
With verbose mode
off
, you receive no notification of those changes or events.
•
With verbose mode
on
, you receive status messages, such as
X8%]
when the switched power ports change from normal
operation to an overload state, or
X%]
when a relay is opened, closed, or toggled. These are not replies to a command
that you send, but they are unsolicited messages that are generated by the equipment.
NOTE:
Verbose mode creates more network traffic than usual, which can slow down network performance.
Verbose mode is usually enabled for troubleshooting and disabled for daily use.
•
By default, when the MLC is connected via Ethernet, verbose mode is disabled in order to reduce the
amount of communication traffic on the network.
•
For a direct RS-232 connection, the controller is set for verbose mode by default.
•
If you want to use the verbose mode (other than mode
0
) with a controller, this mode must be set to “on”
each time you reconnect to the controller.

Set the verbose mode. For

default

= verbose mode is on (enabled)
2
= verbose mode is off, tagged responses
are sent for queries (tagged responses are
enabled)
3
= verbose mode is on (enabled) and tagged
responses are enabled and sent for queries.
