1-8 Module and Development Software Overview
ASCII Terminal Interface
Use an ASCII terminal to enter a BASIC program one line at a time to
your module through port PRT1. The ASCII terminal connected to the
module must be an industrial terminal, workstation, or personal
computer (without the BASIC development software) that
communicates in alphanumeric mode. An ASCII terminal can also be
used to display charts or graphs generated by the BASIC program.
Figure 1.4 shows a typical ASCII terminal interface.
Figure 1.4 Module ASCII Terminal Interface
In this configuration, the RS232 port on the back of your industrial
terminal or personal computer is connected to port PRT1 on your
module. Port PRT1 must be configured as the program port.
See Chapter 3 for additional information on port configuration.
BASIC Development Software Interface (RS232)
Use a personal computer with the BASIC development software
(PBASE) to create a BASIC program that is then downloaded to your
module. PBASE provides an efficient means to edit, compile
(translate), upload, and download BASIC programs. Refer to the
BASIC Development Software Programming Manual, publication
1746-PM001, for additional information on this software.
