How to Modify the Function Parameter of a Discrete Input Module

At a Glance

This parameter defines the properties of the event input module TSX DEY 16FK and TSX DMY 28FK.

Possible parameter values are:

Normal (no event associated with the channel),
Channel by channel status latch (status on 0 or 1),
Channel by channel event processing,
- Event triggered on a rising edge (FM),
- Event triggered on falling edge (FM),
- Event triggered on rising and falling edges.

Event inputs are assigned an (Evti) process number. These numbers range from:

If both transition types are selected on one channel, only one event number is assigned to the channel.

The most important event processing (Evti) is number 0, it can only be assigned to channel 0.

NOTE: The default event number is the first available in the list.

A number entered manually outside the tolerance range is not accepted when validating.

Adding, deleting, or changing the event number is not possible in online mode.

Instructions

The following table shows how to define parameters assigned to event inputs.

Step	Action
1	Open the desired module configuration screen.
2	Select the desired channel group.
3	Click in the cell of the Function column of the channel to be configured. Result: A drop-down menu appears.
4	Click on the drop-down menu arrow. Result: The Channel properties screen appears.
5	Select the desired function.
6	Enter the event number Evt.
7	Repeat the operation for each channel to be configured (from step 3).
8	Confirm the modification with the Edit → Validate menu command.
