Sample Program
The sample program XP89_1.C in the Dynamic C SAMPLES\PLCBUS
subdirectory demonstrates how to calibrate the D/A converter channels.
The basic sample program is designed for the BL1200, BL1600, PK2100,
and PK2200 controllers. Remember to uncomment the lines that apply to
the controller being used with the XP8900 Series expansion board.
To use this program properly, it may be necessary to edit the statements
that initialize the channel, margin, f1, and f2. The program may also be
compiled as is, with watch expressions added to override the assignment
statements (be sure to execute the watch expression AFTER the assignment
statement is executed).
Use the following steps to run the sample program.
1. Compile the program by pressing F3 or by choosing Compile from the
COMPILE menu. Dynamic C compiles and downloads the program
into the controllers memory. During compilation, Dynamic C rapidly
displays several messages in the compiling window, which is normal.
2. Run the program by pressing F9 or by choosing Run from the RUN
menu. It is also possible to single-step through the program with F7 or
F8.
3. To halt the program, press <CTRL-Z>.
4. To restart the program, press F9.
Check the board jumpers, PLCBus connections, and the PC/
controller communications if an error message appears.
See the Dynamic C Technical Reference manual for more
detailed instructions.
