Description
The 1769-ASCII module is a universal two-channel ASCII interface, which provides a flexible network interface for RS-232, RS-485, and RS-422 devices. This module provides a communication connection with ASCII devices.
The 1769-ASCII module supports an input assembly that is accessible
through the Assembly Object (Class 4), Instance 101. The input assembly is
up to 108 words. The module supports an output assembly that is accessible
through the Assembly Object (Class 4), Instance 100. The output assembly is up to 108 words.
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.
