CNC 61.00 Hardware Description CNC 0610510/12 69

10.1.1 Two Serial Interfaces with RS232/RS485

Specification

X RJ45 connector

Two additional serial interfaces with RS232/485 specification in order to connect

printers, barcode scanners etc., which can be initiated by the application program.

Software Access

In the application program the interfaces can be operated via the commands ARD,

AWL, AWR and Atxt (COM2) as well as BRD, BWL, BWR and Btxt (COM3).

10.1.2 X10 - PROFIBUS

The Profibus interface establishes the connection to the Profibus. It is galvanically

isolated from the bus and can be operated up to a maximum of 12 MBaud. The link-

ing to the software, which is independent on the used bus system is realized in the

firmware, and is accessible to the user via the application program. Detailed informa-

tion can be found in the manual "Communication protocol DNC 61.00 for Bus Con-

nections". The status of the bus is displayed via the LED on the front panel of the

option module:
