There are also 16 blank outputs available. These are identi-
fied with an x and can not be reused in a circuit program (in
contrast to flags, for example). The list shows all pro-
grammed blank outputs, and one blank output which is not
yet configured. A blank output, for example, is useful for the
special function “Message texts” (see Chapter 4.4.23), if
only the message text is of significance to a circuit pro-
gram.
2) Analog outputs
Analog outputs are identified by the letters AQ. Two analog
outputs are available, namely AQ1 and AQ2. An analog
output can only be connected with the analog input of a
function, an analog flag AM or an analog output connector.

Flag blocks
Flag blocks are identified by the letters M or AM . These
are virtual outputs, which output the value of their inputs.
LOGO! provides 24 digital flags M1 ... M24 and 6 analog
flags AM1 ... AM6.
