Channel display
The returned value provides different information, based on what is opened or
closed when the reading is acquired:
If no channel or channel pattern is closed when the reading is acquired,
"None" is displayed.
If only a single channel or backplane relay is closed, the channel number is
displayed (for example, 5003 or 5915).
If a channel or backplane relay plus another backplane relay or other
channel is closed, then the channel number is displayed, followed by a +
sign (for example, 3005+ or 3915+). The channel is in the image unless the
last close operation involved only backplane relays.
If multiple channels and/or backplane relays are closed in a channel list, the
last channel specified is stored. Channels take precedence over backplane
relays when stored. However, if only multiple backplane relays are specified,
then the first one is stored.
If a channel pattern is closed, then the first eight characters of the channel
pattern name are returned (for example, mypattern1 is shown as
mypatter).
Buffer configuration (front panel)
When configuring the buffer through the front panel, you must select a reading
buffer. See Selecting a reading buffer (on page 7-3) for more information.
1. Press the CONFIG key.
2. Press the STORE key. The RD BUFFER ATTR menu opens.
3. To view the count and capacity of a selected buffer, select the COUNT or
CAPACITY menu choice. To configure the buffer's append mode, select
APPEND, then ON or OFF.
