1. System Configuration

1.6 Computer link system

The interface of the T1/T1S’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/T1S. The data in the T1/T1S can be read and written by creating simple communication program on the computer. The computer link protocol of the T1/T1S is published in “T1/T1S User’s Manual - Communication Function -”.
