AS-i power supply: switching power supply AS-i 30Vdc 2.4A

Button box for AS-i bus, comprising two illuminated push-buttons green and red

Twido PLC, comprising a module with 12 digital inputs and 8 digital outputs (double terminal block for HE10 connectors) and an RS485 Modbus communication module.

Ethernet Modbus gateway for Twido PLC

Magelis XBT terminal with an alphanumeric screen of a 4 lines by 20 characters, numeric keyboard, 12 function keys and 3 system keys. A 25-point socket associated with a selector switch allows connection to a computer for application downloading.


Communication Case

1.2 Main functions

The main case allows study of following principles:

RS232 point to point local communication: ASCII characters, format, output, control, PC and PLC configuration,

Point to point link via the public switched telephone network, HAYES character set.

AS-i sensor / actuator bus: master / slave, addressing, polling principles,

Multipoint industrial UniTelway and Modbus bus: protocol, transparency and system query principles,

exchange between a PC and a PLC: dialog construction,

internet technology on Ethernet LAN with the TSX Web server function: PC and internet browser configuration, site update and creation of HTML pages,

OFS, OPC Factory Server: object concept enabling computer applications (VB, C++) to access a PLC memory,,

exchanges between PLC’s via an Ethernet LAN: data read/write on remote system,

internet technologies on an Ethernet LAN: IP address, subnetwork name, SNTP server,

remote maintenance or programming with HTML pages or PL7 Pro software and XIP driver.
