I/O Assignment

The following regular or fast I/Os can be configured for use by expert functions:

 

24 I/O References

40 I/O References

TM241•24T, TM241•24U

TM241•24R

TM241•40T, TM241•40U

TM241•40R

Inputs

8 fast inputs (I0...I7)

6 regular inputs (I8...I13)

8 fast inputs (I0...I7)

8 regular inputs (I8...I15)

Outputs

4 fast outputs (Q0...Q3)

4 regular outputs (Q4...Q7)

4 fast outputs (Q0...Q3)

4 fast outputs (Q0...Q3)

4 regular outputs (Q4...Q7)

4 fast outputs (Q0...Q3)

When an I/O has been assigned to an expert function, it is no longer available for selection with other expert functions.

NOTE: All I/Os are by default disabled in the configuration window.

The following table shows the I/Os that can be configured for expert functions:

Using Regular I/O with Expert Functions

Expert function I/O within regular I/O:

  • Inputs can be read through standard memory variables even if configured as expert functions.

  • All I/Os that are not used by expert functions can be used as regular I/Os.

  • An I/O can only be used by one expert function; once configured, the I/O is no longer available for other expert functions.

  • If no more fast I/Os are available, a regular I/O can be configured instead. In this case, however, the maximum frequency of the expert function is limited to 1 kHz.

  • You cannot configure an input in an expert function and use it as a Run/Stop, Event, or Latch input at a same time.

  • An output cannot be configured in an expert function if it has already been configured as an alarm.

  • Short-circuit management still applies on all outputs. Status of outputs are available. For more information, refer to Output Management.

  • When inputs are used in expert functions (PTO, HSC,…), the integrator filter is replaced by an anti-bounce filter. The filter value is configured in the configuration window.

For more details, refer to Embedded Functions Configuration.
