Keys:
<>, <¯>, <PgUp>, <PgDn> - Move the cursor in the selection
window
<Ins> - Selects a channel.
Channel selection:
The available alternatives in the “Channel selection” window are
shown as rows of boxes, which apart from the channel number,
also contain a field for up to 2 characters (see Fig. 5.7). The
channel description consists of a explanatory text and/or a com-
ment entered by the user when configuring the hardware func-
tions (see Section 5.5.5). The corresponding information is dis-
played as the selection bar is moved from one option to the next.
There are two methods of selection:
1. Multiple selection - All the channels, which have just been
selected with the aid of the cursor and the <Ins> key, are in-
dicated by “X”. The cursor jumps to the first available channel
upon opening the window.
2. Single selection - The channel selected is indicated by “X”
and the “X” moves automatically, if a new selection is made.
The cursor jumps to the first available channel upon opening
the window.
Keys:
<¬>, <®> - Move the cursor in the selection window
<Ins> - Selects a channel
<Del> - De-selects an option (multiple selection only)
<-> - Inverts a channel
(binary inputs only).
The system only permits channels to be selected it considers to
be plausible, otherwise a warning bleep sounds (but there is no
error message). Examples of implausible selections are setting a
channel defined as a current input as a voltage input, or at-
tempting to assign a signal to an output (relay or LED) which is
already occupied.
