1.6 Programmer port function
The interface of the T1-16S’s programmer port is RS-232C. Normally this port is
used to connect the programmer. However, this port can also be used for the
computer link function.
The computer link is a data communication function between computer or operator
interface unit and the T1-16S. The data in the T1-16S can be read and written by
creating simple communication program on the computer. The computer link protocol
of the T1-16S is published in “T1-16S User’s Manual
