SLIO - the smart I/O-system

Demand for a more compact and flexible automation solutions with a reasonable price-performance ratio has been constantly increasing. With the development of the completely new I/O system SLIO®, VIPA is setting a new standard in the automation sector. The VIPA I/O system SLIO combines high functionality with an intelligent mechanical concept and an extremely compact design. SLIO® is a synonym for slice-I/O. With its very compact design, the system can be set-up step by step to exactly meet the requirements of the application. The Interface Modules (IM) for PROFIBUS-DP, CANopen, PROFINET, EtherCAT and Modbus can support up to 64 Electronic Modules (EM). The Power Modules (PM), which are contrasting in color to Signal Modules (SM) and Function Modules (FM), supply voltage to the Electronic Modules. Decoupled potential groups can be defined if required.

The Electronic Modules are connected to the Terminal ModuleTM using a secure plug-in mechanism. The Terminal Module is comprised of a clamp, connection of Electronic Modules and mechanical bus connector. Therefore, if maintenance or repair are required, only the Electronic Module will have to be exchanged by simply pulling it out of the Terminal Module. Wiring and mounting on the 35mm DIN rail will remain unchanged. The staircase-shaped cage, which clamps on the Terminal Module offers fast, clear, and secure wiring. With the integrated status-LEDs and the labeling strip on the front, an exact state monitoring of channels on the Electronic Module is possible. The new backplane bus system with a transmission rate of 48Mbit/s offers very short response times with a signal processing of less than 20µs. SLIO® is one of the most powerful and cost-effective decentralized systems available in the market.

The space-saving Interface-Module represents the interface between process level and bus system. All control signals are transmitted to the Electronic Module through the internal backplane bus.

Electronic Module for connection of sensors and actuators, registration of digital and analog signals in and out of the process.

Power Module for refreshing of backplane bus power. The double-component-design ensures easy maintenance due to the separation of electronics from the Terminal Module.

Electronic Module for realization of automation requirements, e.g. fast counting. For measuring and positioning the following function modules will complement the SLIO® System in the future:

There are digital input and output modules with order memory (FIFO) available to buffer the signal edges. These terminals are marked with the abbreviation ETS (Edge Timestamp System). SLIO ETS offers a temporary significantly improved exactness at the µs area for all supported fieldbus systems.

Signal modules (SM) to connecting sensors and actuators are the interfaces of the system to the process. Analog signal modules acquire the analog control signals (e.g. measurement data) to and out of the process level. Depending on the application and type the control signals are acquired from the process level and converted into interpretable signals for controlling. Analog output modules convert the internal control signals into signals suitable for the process level.

A variety of different analog signal modules accurately provide the inputs and outputs that are required for each task. The analog modules differ in the number of channels, voltage and current ranges, isolation, and diagnostic and alarm capability.

The SLIO DMS modules allows direct connection of a resistor full bridge (DMS) or load cell in the 4- or 6-wire connection. Power supply already integrated.

Typical fields of applications

The module allows the measurement of electric data for counting energy and power measurement. Here, the voltage measurement of each phase is directly measured and the current is measured indirectly via current transformers. In consideration of the permissible total current, you can also perform an energy measurement on devices, which are within the same phase.
