Timer 1Ch

The Timer 1Ch starts a timer which can be configured by timer mode and interval. According to the specific timer mode the timer is started, if the configured condition becomes TRUE (TON, TP) or the condition becomes FALSE (TOF).

Optionally, a Boolean signal can be selected for the Enable Execution input so that the algorithm is only active if the value of the selected signal is TRUE.

Configuration options

• Operator: Specifies whether the input value should be greater than, greater than or equal to, equal to, less than or equal to, or less than the threshold.
• Threshold: Signal threshold.
• Timer Mode: mode of the timer:
• TON: The TON timer is a switch-on delay timer that enables the output after the threshold condition becomes TRUE and the timespan specified in the interval has elapsed.
• TOF: The TOF timer is a switch-off delay timer that disables the output after the threshold condition becomes FALSE and the timespan specified in the interval has elapsed.
• TP: The TP timer is a pulse generator that activates the output for the time specified in the interval after the threshold condition becomes TRUE.
• Interval: Time interval of the configured timer.
• Tolerance (optional): Tolerance value for the Equal / NotEqual comparisons.

Output Values

• Output: Shows the output value which is affected by the configured timer.
• Elapsed Time: Shows the elapsed time of the timer.

Standard HMI Controls

For the Timer 1Ch algorithm, the following HMI controls are available for generating an Analytics Dashboard:

1. The Timer Control visualizes the output value Elapsed Time.

2. The Table Control or Multivalue Control visualizes all output values: Output, Elapsed Time.

Alternatively, customer-specific HMI controls can be mapped in the Timer 1Ch algorithm using the Mapping Wizard.
