About us
At a Glance
The counting modules TSX CTY 2A and 4A have several possible input interface types, according to the selected counting function. The interface is configured using the configuration editor.
Procedure
The table below summarizes the procedure for configuring the input interface of a TSX CTY2A or 4A module.
Step
Action
1
Open the module to be configured.
2
In the channel field: select the counter (i.e. the channel) concerned.
3
In the general parameters field: select the counting function required.
Result: the configuration screen appears
4
In the general parameters field: select the task for the exchange of objects.
5
In the Input interfaces field, select from the drop-down list in the first field:
  • the type of input interface.
The details of the different types of interface are described in the section named Description of counting module input interfaces.
Note: In up or down counting only, the IA Input selection is frozen.
6
Select input filtering from the drop-down list of the second field:
  • Solid state contact (reduced filtering), or
  • Mechanical contact (anti-rebound filtering, pulse frequency limited to 100 Hz).
7
If an incremental encoder interface is selected at step 5, fill in the following fields, otherwise, go to step 8 to complete the configuration:
  • Line check (is used to indicate a channel fault in the event of a break in the physical connection of the encoder).
  • Multiplication by 1 or by 4 (is used to increase counting accuracy at the expense of maximum frequency).
8
Configuration of the input interface is complete.
Confirm the new configuration. To do this:
  • scroll down the Edit menu and select the Enable command.
