Activity Monitoring
Activity Monitoring is used to detect if any Input or ID is active for too long or also to run a cumulative total of the active time for any Input or ID. A good example would be to check if an air conditioner has been running continuously for too long. Another example would be to calculate the cumulative run-time of a generator in order to plan oil changes.
Configuring the Analog Inputs (AXON-8A only)
The following window allows complete configuration of the Analog Inputs:
The A, B and C parameters allow sensor linearity, gain and offset to be fine-tuned, respectively. The corresponding equation is shown in the View window. The D parameter is used for logarithms as also shown in the equation.
The 4 sections at the bottom of the screen will be found in most Configuration windows of the AXON/NEURO, and they have the same functionality in all these different Configuration screens.
Conditionally Locked State
This screen is used to set which (if any) other input (or ID) in the AXON/NEURO will lock the current input. In the example below, if the 1P3 Flag (Sunrise) is Active, then 1A1 will be locked (or muted).
Alarm Configuration
This screen is used to configure which of the 5 Alarm Call Lists (ACL) will be called-up if the High or Low limits are exceeded.
Action
This screen is used to configure special actions that can occur should the alarm thresholds be exceeded.
These actions can be:
- To put data from any input into the Data Log (input is selectable from the drop-down on the right side)
- To Force a Relay ON (Relay is selectable from right-side drop-down)
- To Force a Relay OFF
- To Release a Relay (set it free)
- To Pulse a Relay
- To Count Up, Down or Reset one of the 8 Counters (Counter is selectable on right-side drop-down)
Linked To
The Linked To screen is for information only. It displays any other Input or ID that would have an influence on operation of the current input. In the example shown below, 1D4 is shown to be Locking Out 1A1 in the case where 1D4 is Active.
Counters
The Counters screen allows configuration of the event counters. These counters can count up or down, and be reset by external inputs or IDs. Thresholds are set in the Action Limits fields. The Minimum and Maximum values define settings past which the counter does not count up or down any more.
Configuring the Digital Inputs (AXON-8D only)
The following screen shows the configuration window for the Digital Inputs. The main setting is to determine whether the input will become active on a High logic level, or on a Low logic level.
Flags
AXON/NEURO units have 5 internal Flags that can be useful to detect (and take action on) various important events.
The 5 Flags are:
- 1P1-Boot Flag. This flag becomes active whenever the AXON/NEURO boots up. It is automatically logged in the System Log, but it can also be used to trigger logging or counting of other events.
- 1P2-Power On Flag. This flag becomes active whenever an AXON/NEURO starts-up from a power-down state. It can indicate a power failure at the site, and is different from the Boot Flag.
- 1P3-Sunrise Flag. This flag becomes active whenever the sun has risen. It obviously requires that the site’s Latitude and Longitude be entered into the appropriate fields in the Date, Time & Location screen.
- 1P4-Connection Flag. This Flag becomes active after 3 failed login attempts to the AXON/NEURO. This event is logged, and can also initiate an alarm to notify site operators about the failed attempts.
- 1P5-Supply Voltage Flag. This flag becomes active when the AXON/NEURO’s power supply voltage falls below 4.75 Vdc or if it rises above 30.6 Vdc. For detection of other, higher voltages (for example if an AXON is being powered from a 24 Vdc Bus), a Math function can be used in conjunction with the 1P5 Value to set different measurement limits.
Math Functions
Math functions are used to perform different operations on various Inputs or IDs (the operands).
The drop-down list below shows the different operations that can be performed on the operands. Note that the number of operands will automatically adjust from 1 to 4, depending on the nature of the operation selected. The information window, located just above the operands, shows the actual equation with the relation of the different parameters.
Besides this particularity, the Math Function settings operate in exactly the same way as the Analog input settings.
Ping
The Ping screen allows configuration of the Network Ping’s target IP address, as well as the number of retries and time-out before triggering an action or alarm. A test button is available to check operation while configuring.
Schedulers
This screen allows configuration of up to 8 scheduled events. These events can be set up to occur on a yearly, monthly, day-of-the-month, day-of-the-week or hourly basis. Combinations of these parameters are also possible. For example, you can set an event to occur every Monday at 3AM during the month of February.
To set events to happen on the first Monday of every month for example, you can select Yearly, unselect Daily, and select days 1 to 7. Then unselect 7/7 and select Monday.
For the 2nd Monday, select days 8 to 14,
For the 3rd Monday, select days 15 to 21,
For 4th Monday, select days 22 to 28,For the 5th Monday, select days 29 to 31,
