7.21 Analog Values and Trending
Trending of analog values is supported on all of the panels/networks 4–20 mA modules.
The only limitation is that the gateway will only actively read analog values for up to 10
analog modules at a time. All the analog values on all the modules can be read as long as
a separate poll is sent for these points in groups of up to 10 points at a time, following the
rules outlined below. Refer to
• Accept a poll for up to any 10 analog (4–20 mA) points per gateway.
• Requests for more points than this are rejected with an exception code.
• If any of the points in the request are not 4–20 mA modules then the gateway rejects
the request with an exception code.
• The first poll for analog values is an initialization poll. This initialization poll informs the
gateway to start acquiring analog values for these points at 5 second intervals.
• Points are only polled on the NFN if the 4–20 mA module is in at least the first level of
alarm status. If the point is normal then the gateway returns a value of zero.
NOTE: The first response to an analog point poll is zero. This response is an initialization
confirmation from the gateway.
