Analog Channel 1 Update Time
When the analog input expander is used the channel will generate analog information that is stored in the
variable associated with the analog expander. The data can be programmed to be sent in various incremental
values. As many elements that are monitored by sensors operate slowly we recommend using the longest times
possible. This also reduces the risk of disturbances due to interference as the input is averaged over the period
of time being sampled.

Use the [1] and [3] keys to scroll the channel time settings. For more information about the list control data entry
refer to the section List Control Data Entry (see page 344).
Analog Channel
1 Differentiate On Send Value
The value that is configured is constantly monitored against the last value that is sent to the system controller
and if a change has occurred greater than the amount programmed and differentiate on send option is enabled
the channel will send an update and start the comparison process again.
The value that is programmed is an offset of the raw input value to the analog expansion module device. The
last sent value is retained and any input is sampled and averaged before being compared to the differentiate
value.

To enter a value (0-255), use the keypad as explained in section Entering Decimal Numbers (see page 341) and
press [ENTER].
Programming Analog Channel 2, 3 and 4
The programming screens for channels 2, 3 and 4 are identical to channel one and you will be prompted with
each channel screen as you press the [ENTER] key. Each channel operates independently of each other.
