When RTS is set to zero, all channels are acquired freely and independently with no idle time. A channel
configured at a high filter frequency can be acquired multiple times in the time that a single acquisition is made for a
channel configured at a lower filter frequency.

6.4.1 Real Time Sample Value (Word 0)

The real time sample value determines when the module will scan its input channels for
available data. After the channels are scanned, the data is made available to the PLC.
The valid range for the real time sample is 0
Note: The Real Time Sample rate must be greater than or equal to the slowest channel
step response time. See Table 6-5 to determine the proper RTS rate.
Note: The configuration file can also be modified through the control program, if
supported by the controller. For information on configuring the module using
RSLogix 500 (with MicroLogix 1500 controller), see Chapter 5; for RSLogix 5000
(CompactLogix controller), see Chapter 4.

6.4.2 General Configuration Bits (Word 1)

Word 1 is used to configure general module properties like enabling and disabling
HART, setting a HART handle time for HART messaging, and selecting one of three
scanning schemes for HART pass-through messages. The table below shows the
available settings for word 1.
