Basics of the "Modules/Slots" procedure

The modules/slots procedure enables simplified configuration and parameterization of multifunctional EtherCAT devices. The configuration is carried out in TwinCAT via the "Slots" tab.

Basics of the "Modules/Slots" procedure 1:
Configuration in the "Slots" tab using an EL8601-8411 as example
1. The operating mode is defined for each "SlotGroup" by assigning a maximum of one "ModuleGroup". When the "SlotGroup" is selected in the left-hand field, the "ModuleGroups" available for this "SlotGroup" with the associated "Modules" are displayed in the right-hand field.
2. "ModuleGroups" describe the possible combinations of the individual "Modules". In this way, the configuration of invalid combinations can be excluded. The operation mode of the group is explained in short form in the "Description" section.
3. Each "Module" has a defined "ModuleIdent" number that is fixed to an operation mode and the corresponding process data and CoE objects.
In the "ModuleIdentList", all "ModuleIdents" of a "ModuleGroup" are displayed according to the frequency of their use (see Fig. above CNT_2xDI).
4. Each SlotGroup must be assigned exactly one "ModuleGroup" using the "<" (assign) and "X" (remove) buttons.
The process data and the CoE objects are automatically adjusted according to the selected "ModuleGroup", in the respective SlotGroup.
In the TwinCAT "Product View" tab, the pin assignment is displayed according to the configuration (see chapter Connections in the "Product View" tab).

Notes on configuration with the modules/slots procedure

  • The TwinCAT system must be in "ConfigMode" Basics of the "Modules/Slots" procedure 3: to perform the configuration.
  • If a "SlotGroup" is to be operated without function, the "ModuleGroup" "Empty" must be selected. A "SlotGroup" without an assigned "ModuleGroup" is not allowed.
  • If the configuration is changed, the settings in the Setting objects of the changed "ModuleGroups" are reset to the factory settings.
  • To reset the product to the delivery state (factory settings), the "PreOP" state is required before the "Restore default parameters" object is used.
