Module 9113 Receive ASCII characters via data interface

You must first assign the interface to the PLC and initialize it with Module

Module 9113 reads a single ASCII character from the receiving buffer of a

If there is more than one character in the receiving buffer, the first is sent and

the others are stored in a special buffer.

You can interrogate the current state with Module 9102, bit 8.

As long as data remains in the buffer, no further characters are collected from

the interface.

If MP5030.2 < 2, the characters cannot be read from the interface until the line

with the character requested in the protocol has been executed.

Store the result in a word at least so that the values to 255 will be
