4.5 Program examples

In the following examples, the PC reads status S1 from two COMPAX devices, for which the following parameters have
previously been set:

Device 1:

 P194 = 1 P195 = 9600bit/s

Device 2:

 P194 = 5 P195 = 9600bit/s

4.5.1 

BASIC program with BCC

!

P196 = 8 in both devices

OPEN "com2:9600,N,8,1" FOR RANDOM AS #1----- Initialization of interface as #1 (channel 1)

com2:

serial interface COM2

9600:

9600 baud transmission rate

N:

no parity bit

8:

8 bit word length

1:

1 stop bit

text$ = "1S1" ---------------------------------------------------- device 1 is to be interrogated for status 1
GOSUB output ------------------------------------------------- calls up subprogram "Output"
GOSUB read---------------------------------------------------- calls up subprogram "Read"
PRINT text$ ----------------------------------------------------- outputs read value to screen
text$ = "5S1" ---------------------------------------------------- device 5 is to be interrogated for status 1
GOSUB output ------------------------------------------------- calls up subprogram "Output"
GOSUB read---------------------------------------------------- calls up subprogram "Read"
PRINT text$ ----------------------------------------------------- outputs read value to screen
END --------------------------------------------------------------- program end

output: ------------------------------------------------------------ start of subprogram "Output"
bcc = 0------------------------------------------------------------ bcc is set to 0
FOR a = 1 TO LEN(text$) ----------------------------------- loop performed for each character in text$
 bcc = bcc XOR ASC(MID$(text$, a, 1)) ----------------- XOR operation on all characters to bcc
NEXT a ----------------------------------------------------------- end of loop
PRINT #1, text$ ------------------------------------------------ text$ is output with concluding CR to #1

PRINT #1, CHR$(bcc); --------------------------------------- BCC in bcc is output as character without CR to #1

RETURN --------------------------------------------------------- branch back to main program

read:--------------------------------------------------------------- start of subprogram "Read"
INPUT #1, text$ ------------------------------------------------ value is read from #1 to text$
a$ = INPUT$(2, 1) --------------------------------------------- characters LF and ">" are read from #1

bbcc = 0 ---------------------------------------------------------- bbcc is set to 0
FOR a = 1 TO LEN(text$) ----------------------------------- loop performed for each character in text$
bbcc = bbcc XOR ASC(MID$(text$, a, 1))--------------- XOR operation on all characters to bbcc
NEXT a ----------------------------------------------------------- end of loop
ebcc = ASC(INPUT$(1, 1)) ---------------------------------- BCC is read from #1 to ebcc
IF ebcc = bbcc THEN RETURN---------------------------- BCC read into ebcc is compared with

calculated BCC in bbcc; if values are same,
branch back to main program

PRINT "Transmission error !!!" ----------------------------- error message output on screen
RETURN --------------------------------------------------------- branch back to main program
