eIO-RTU Setup Guide

When first configuring your RTU, you will need to verify the time and date on your home page. Your RTU is configured by default to use Eastern Standard Time (GMT-5) and will automatically adjust for Daylight Saving Time. If your location is not in the Eastern Time zone, please make sure to set your Time Zone first. Using an incorrect time zone will cause any time-based rules to activate at the wrong time.

To set your Time Zone:

• Go to Settings > Time/Date
• Enter your local Time Zone (for example, -5 for Eastern Time Zone, -6 for Central Time Zone, -7 for Mountain Time Zone, -8 for Pacific Time Zone)
• Make sure the Use NTP Update box is checked (when this box is checked, the Hour Meter will update its time from the NTP server every 30 minutes by default)

Note: If an ethernet connection is not supplied during normal operation, the RTU will be unable to receive NTP updates.  To fix this provide an ethernet connection and either manually correct the time in the time textbox or set NTP Interval text box to 1, receive an NTP update, and set it back to 30 afterwards.

Once the expansion modules are connected to the same DIN rail as the eIO-RTU CPU, they can be configured through the web interface.

Note: Skip this section if only the CPU Module was purchased

Navigate to Configure > CAN Settings.

• Click the Edit icon for the expansion module.
• Enter a description.
• Select the appropriate device type (e.g., EIO-8RL or EIO-10DI).
• Click Save.

Note: The Device ID and CAN ID are assigned automatically. A successfully configured module will display a green Online indicator.

Assigning the Inputs/Outputs

Navigate to Configure > Inputs/Outputs Settings.

By default, DIN1, DIN2, RELAY1, and RELAY2 are assigned to the eIO-CPU. Enable the additional inputs or outputs you want to use by selecting their checkboxes, then select the expansion module and physical I/O number to assign to each one.

For example, when configuring an EIO-10DI:

• IN2 → DIN2
• IN5 → DIN3
• IN6 → DIN4

The configured inputs and outputs will appear in this assigned order under Services > In/Out.

The Tasks page allows you to create up to 32 automatic condition-based events. Tasks use IF…THEN logic to monitor a condition and perform an action when that condition is met. A second condition can be added using AND, OR, or NOT logic.

From the Tasks page, click the indicator in the Use column to enable or disable a task:

• Green: Task enabled
• Red: Task disabled

Click the Edit icon next to a task to open the Set Task page and configure its conditions and actions.

Configuring a Task

Each task consists of a trigger (Device A / Data A), an optional second condition (Device B / Data B), and an action (Device C / Data C).

• Task Select: Automatically determined by the task selected on the previous page.
• Task Name: Enter a name up to 15 characters.
• USE: Enables the task. If an error is detected when saving, USE will automatically be disabled and the field containing the error will be highlighted.
• LOG: Records an entry in the system log each time the task executes.
• Email: Sends an email each time the task executes.

Device A / Data A – IF Condition

Device A determines what the task will monitor. Data A specifies the value or state that must be met.

The available Data A formats include:

• Minute: mm
• Hour: hh using 24-hour time.
• Day: dd
• Day of Week: 1 Sunday, 2 Monday, 3 Tuesday, 4 Wednesday, 5 Thursday, 6 Friday, 7 Saturday, 8 Weekday, 9 Weekend.
• Time: hh:mm using 24-hour time and leading zeros. Example: 07:30 or 14:05.
• Date: yy/mm/dd using leading zeros. Example: 26/08/19.
• Relay: Enter the relay number followed by + for ON or - for OFF. Example: 01+ or 01-.
• Temp: Enter >, =, or < followed by the temperature in °C. Example: >40.
• Volts: Enter >, =, or < followed by the voltage. Example: <10.
• Analog: Enter the analog input number, comparison operator, and value. Example: 3<123.
• Digital: Enter the input number, data type, comparison operator, and value. Example: 1F>7500.

For Digital conditions, the data type is case-sensitive:

• S – Input state (ON/OFF)
• C – non-resettable counter
• c – Resettable counter
• F – Frequency in 1/1000 second
• P – Period in 1/1000 second

Device B / Data B – Optional Second Condition

A second condition can be added using Device B and Data B. Data B uses the same syntax as Data A.

Select the desired relationship between Device A and Device B:

• AND: Both Device A and Device B must be true.
• OR: Either Device A or Device B must be true.
• NOT: Device A must be true while Device B is not true.

For example:

IF Digital Input 1 is ON AND Digital Input 2 is ON THEN Relay 1 ON.

Device C / Data C – THEN Action

Device C determines what the task controls when its conditions are met. Data C identifies the specific output, device, or function.

Available Device C options include:

• RELAY: Control one or more relays. Enter up to four relay numbers separated by commas. Example: 1,2,3,4.
• COUNTER: Add a count to a digital input counter. Enter 1 or 2 for the corresponding digital input.
• DELAY: Delays activation of a relay. Enter Relay#,Seconds. Example: 1,180 delays Relay 1 for 180 seconds.

Action

The Action field determines what happens to Device C when the task conditions are met:

• ON: Turns Device C ON.
• OFF: Turns Device C OFF.
• TGL: Toggles Device C between ON and OFF.
• RESET: Resets the selected counter or supported device.

Once all conditions and actions are configured, click Save. If any entered data uses invalid syntax, the corresponding field will read error.
