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:

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

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

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

oIf 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.

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

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

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

oWhen 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.
