4.5 Setting the cycle time for access to the I/O modules

In the L-force Controller a central bus cycle task is selected, which is valid for the processing of all

fieldbuses and for the I/O modules connected via the backplane bus.

• This selection is a default setting and can be overwritten in the respective bus master nodes

(EtherCAT master, CANopen_Manager, I/O module coupler, ....).

• If you require a shorter cycle time for the backplane bus that the one selected in the L-force

Controller, you can select a faster task for the I_O_Modul_Koppler on the Module I/O Mapping

tab:

The following applies to the I/O modules on the I_O_Modul_Koppler:

• At first, the »PLC Designer« defines a processing task for the PLC for generating the I/O image.

An individual bus cycle task can be defined for each individual module, within which the process

image for the module is then created.

• Altogether three different tasks for the I/O modules can be defined. The limitation to three

tasks is determined by the system on the basis of the backplane bus specification.

• The backplane bus controller uses two internal bus cycle groups for each task; one for input

signals and one for the outputs. A total of six groups is provided.
