Publication

1769-IN068B-EN-P - May 2005

Configuration File

The 1769-ASCII module supports a configuration assembly that is accessible

through the Assembly Object (Class 4), Instance 102. The configuration

assembly is 31 words. The addresses assume a 16-bit data structure where all

16-bit values are INT

(1)

. The least significant word occupies the smaller byte

addresses.

(1)

INT = Integer range of -32768 to +32767 decimal, 0000 to FFFF hexadecimal.
