Cascades enable distributed SL VARIO modules without complex wiring.
What is a cascade configuration?
A cascade configuration is used to arrange the modules of an SL VARIO application spatially distributed in several control cabinets and still operate them as one logical unit. This simplifies installation and maintenance in complex systems.
Components of an SL VARIO cascade:
A typical cascade consists of the following components:
- Base unit (BE): Contains the central module (ZMV) of the SL VARIO application. There is only one base unit per cascade.
- Peripheral units (PE): Up to five additional units, each containing a DNSL-CMV cascade module instead of a central module. These units house the peripheral modules of the application.
Maximum number of modules and peripheral units:
A maximum of 15 modules can be used in a cascade, including the central module in the base unit and all modules in the peripheral units.
Up to 5 peripheral units, each with a CMV module, can be operated per base unit (with central module). The addressing of the modules in the peripheral units starts with values greater than 0, which are defined via the AD inputs on the CMV module of the respective peripheral unit. The central module in the base unit always has the address 0.
