Presentation

In order to communicate with an intelligent environment, Twido compact and modular programmable controllers offer an RS485 serial communication port on the module as well as an optional type RS 485 or RS 232 link.

These two ports allow Twido compact and modular controllers to use four communication protocols: Programming, Modbus, ASCII, and Remote link.

Description

1

Compact base controllers have the following on the front panel:

1An RS485 serial port, with mini-DIN type connector for connection to the programming terminal.

2A slot for fitting a 2nd optional port (RS 485/RS232) using TWD NACppp adapters.

Modular base controllers have the following on the front panel:

1An RS485 serial port, with mini-DIN type connector for connection to the programming terminal.

The slot for fitting a 2nd optional port (RS 485/RS232) using adapters TWD NACppp is located behind the removable cover 2 of a TWD NOZ pppp interface module 3 or a TWD XCP ODM display module 4.

The interface and display modules connect to the left-hand side of modular base controllers.

\"Remote link\" protocol

\"Remote Link\" decentralised I/O:

Each compact or modular base controller can be extended by means of Twido base controllers used either as an I/O extension, or as a local \"reflex\" controller. v When used as an I/O extension, these base controllers cannot take any I/O extensions.

v When used as a local \"reflex\" controller, these base controllers have their own application program. Internal words are reserved for automatic exchange of information between the base controllers.1Base controller.
