EtherCAT System

Ma.Vi.’s EtherCAT Slave Modular System, on Omega bar (Ω DIN EN50022), is today composed by 6 modules with configurable features and advanced functions, and it is countinuosly growing.
It was born from deep experience in plants requirements and offers high flexibility together with precision and modularity.
All input/output signals to/from modules have less than 10 µSec delay with respect to the EtherCAT packet sent by the Master.
The Slave Modular System can be driven by any EtherCAT Master (TwinCAT, Ma.Vi. mvPMC eCAT,  others).

Here is a list of modules (click on the menu link for short description or on the underlined name for full data sheet):

1) Bus Coupler :                mvTBI-EBC

2 RJ45  bus connection with bypass function in case of power off.
It interfaces and powers following modules through e-bus.

2) Analog Input :               mvTBI-E8AI

8 independent  analog input channels, individually configurable on: 
±10V, ±5V, 0-10V, 0-5V, 4-20mA, 0-20mA, ±10mA, ±20mA.
16-bit resolution for unipolar inputs.

3) Analog Output:              mvTBI-E4AO

4 independent analog output channels, individually configurable on:
±10V, ±5V, 0-10V, 0-5V, 4-20mA, 0-20mA, ±10mA, ±20mA.
16-bit resolution for unipolar outputs.

4) Digital Input Output :      mvTBI-E8DIO

8 digital input channels (4 inputs 24V and 4 inputs 5V) and
8 digital output channels (4 outputs 24V and 4 outputs 5V).
Inputs at 5V can acquire Sink or TTL signals.
Outputs at 5V can be configured as OpenCollector or Totem-Pole.

5)Encoder/SSI Interface:     mvTBI-E4ES

4 independent acquisition channels individually configurable.
Available input modes:
SSI or QIE (Quadrature Incremental Encoder) or TPE (Two Pulse Encoder). 32 bit counter for quadrature encoder.

6) Power Expander:             mvTBI-EPWE

Power Expansion for Field and E-Bus power.
Field Voltage supplied: 24V 5%.
Field Max Current supplied: 10A.
E-Bus Voltage supplied
2A. No configuration required.
Trasparent for EtherCAT Master.

The strong point of slaves is total configurability: EtherCAT Master can set up each slave by Mailbox. Thus only one type of module is used for different types of signals, only one type of module is stocked as spare part, and a new sensor or device can be serviced simply changing configuration.

Ma.Vi.  has developed a mezzanine-card, mvPMC-DSW, on bus PCI, in which EtherCAT Master has been implemented; moreover the same board can produce also other communication protocols.
