Product Overview

The ABB TA561-RTC, ordering number 1SAP181400R0001, is a real-time clock option board for compatible ABB AC500-eCo programmable logic controllers. It adds a battery-backed clock function to supported processor configurations, allowing PLC applications to work with date and time information for scheduled operations, event recording, and time-dependent control tasks.

In a machine control cabinet, the TA561-RTC is useful when the controller needs a clock function that remains available independently of the normal control supply. For example, a machine may record when an alarm occurs, maintain timestamps for production events, or execute an application sequence according to a defined schedule. These functions depend on the PLC program and the capabilities of the installed processor.

The TA561-RTC is a dedicated clock accessory rather than a communication adapter. Unlike the TA562-RS, it does not add a COM2 serial interface. The TA562-RS-RTC combines both functions in one option board, whereas the TA561-RTC is intended for applications that need the real-time clock without the additional serial interface.

When selecting the TA561-RTC for an existing installation, the exact processor model and hardware generation must be checked. Battery provision is also relevant: the associated CR2032 battery is purchased separately. Correct installation and clock verification help ensure that the application receives valid time information after the controller is restarted.

Product Features

  • Real-time clock function: Supplies date and time information for supported PLC application tasks.
  • Battery-backed timekeeping: Supports clock retention during loss of the normal control supply when the required battery is installed and serviceable.
  • Processor option-board integration: Adds clock functionality through the designated interface on compatible AC500-eCo hardware.
  • Separate battery provision: Uses a CR2032 battery, which must be obtained separately.
  • Event timestamping support: Can support applications that associate alarms, operating events, or process records with time information.
  • Scheduling support: Enables time-dependent application functions where the PLC program uses the clock data.
  • Dedicated clock accessory: Provides a clock-only option for installations that do not require the combined RS-485 interface available on the TA562-RS-RTC.

Working Principle

The TA561-RTC supplies the processor with real-time clock information. The clock maintains date and time values, which the PLC application can read and use when executing time-dependent functions.

A simplified arrangement is:

AC500-eCo Processor → TA561-RTC → Date and Time Data → PLC Application

For example, a packaging machine may record the time of an alarm so that maintenance personnel can compare the event with production records. A pump controller may use time information as part of a programmed operating schedule. In both cases, the TA561-RTC supplies the clock function; the PLC program determines how the information is used.

The battery supports continued timekeeping when the controller’s normal power supply is interrupted. Without a serviceable battery, the clock may not retain the correct time through an extended power-off period. The battery must therefore be installed and maintained according to the applicable hardware instructions.

After installation, the clock should be set or synchronized as required by the application. The commissioning check should include verifying the displayed or read date and time, interrupting power according to the approved test procedure, and confirming that the clock retains the expected values after power is restored.


Role in the AC500-eCo PLC Architecture

The TA561-RTC supplies timekeeping functionality to the PLC application. It does not perform logic execution, process field inputs, or provide a serial communication channel.

Installation and Maintenance

  1. Verify the complete part number: Confirm TA561-RTC and ordering number 1SAP181400R0001 against the installed accessory and processor documentation.
  2. Check processor compatibility: Identify the exact AC500-eCo processor model and hardware generation before fitting the clock option.
  3. Isolate the controller: Follow the processor’s shutdown and isolation procedure before installing or removing the option board.
  4. Inspect the option-board interface: Check the designated connection for contamination, damaged contacts, or mechanical obstruction.
  5. Install the board correctly: Align the TA561-RTC with the appropriate processor interface and seat it according to the applicable hardware instructions.
  6. Check the battery requirement: Obtain the specified CR2032 battery separately and confirm that it is suitable for the installed hardware.
  7. Inspect the battery holder: Check the holder and contacts for contamination or damage before inserting the battery with the correct polarity.
  8. Restore the processor configuration: Refit any covers and restore the controller’s normal configuration before applying power.
  9. Set the clock: Configure the correct date and time using the supported application or controller procedure.
  10. Verify timekeeping: Confirm that the PLC reads the expected clock values and that the application handles them correctly.
  11. Check backup behavior: Follow the approved test procedure to confirm that the clock retains time through the intended power interruption.
  12. Record the maintenance details: Document the option-board ordering number, battery replacement date, clock settings, and test results.

Technical FAQs

Does the TA561-RTC include the backup battery?

No. The CR2032 battery is purchased separately. Confirm the battery requirement and installation procedure for the specific processor configuration.

How does the TA561-RTC differ from the TA562-RS-RTC?

The TA561-RTC provides the real-time clock function. The TA562-RS-RTC combines a real-time clock with a COM2 RS-485 serial interface. The choice depends on whether the application also requires the additional serial port.

What happens to the clock when the PLC loses power?

With a correctly installed and serviceable backup battery, the clock can retain time during a power interruption. If the battery is missing or depleted, the clock may lose its retained time and require resetting.

What should be checked if the PLC reports an incorrect date or time?

Check the clock settings, battery installation and condition, and the processor’s supported clock configuration. Also verify whether the application resets or synchronizes the clock during startup.
