Module 9106 Receive Binary Data Through Data Interface - HEIDENHAIN TNC 426 PB/M Technical Manual

8 – 36

Module 9106 Receive binary data through data interface

You must first assign the interface to the PLC and initialize it with Module
9100.
Module 9106 reads a block of binary values from one of the two interfaces to
the word memory of the PLC. The transfer is in the form of ASCII-coded
hexadecimal values. Every two ASCII characters from the serial interface
make one byte in the binary block.
The length of the read binary block is returned as the initial variable.
Can only be called in a submit job or spawn job!
Call:
PS B/W/D/K <Interface>
0: RS232
1: RS422
PS K/B/W/D <Number of the first byte in the binary block (0 to 1023)>
