Ex. 2: BASIC program for executing an input command with checksum (RS232C, ASCII mode) (Toshiba version of Advanced BASIC-86 Ver. 3.01.05J)

◊ Checking if the maximum frequency setting has been changed correctly

1) Examples of programs
10	OPEN "COM1:9600,E,8,1" AS #1	--- 9600 baud, even parity, 8-bit length, 1 stop bit
20	INPUT"Send Data=";A$	--- Reads in data to be sent to the inverter.
30	S$="("+A$+"&"	--- Adds “(“ and “&” to the read data in.
40 S=0
50	L=LEN(S$)
60	FOR I=1 TO L	Calculates the number of bits (checksum).

70S=S+ASC(MID$(S$,I,1))

80NEXT I

90CHS$=RIGHT$(HEX$(S),2)

100	PRINT #1,"("+A$+"&"+CHS$+")"	--- Sends the data including the checksum result
		to the inverter.
110	INPUT #1,B$	--- Receives data returned from the inverter.
120	PRINT "Receive data= ";B$	--- Displays the data received.
130	GOTO 20	--- Repeats.
2) Examples of program execution results
Send Data=? R0011		--- Reads the maximum frequency (0011).
Receive Data= (R00111F40&3D)		--- 1F40 (Maximum frequency: 80 Hz)
Send Data=? W00111770		--- Changes the maximum frequency to 60 Hz
		(1770).
Receive Data= (W00111770&36)
Send Data=? R0011		--- Reads the maximum frequency (0011).
Receive Data= (R00111770&31)		--- 1770 (Maximum frequency: 60 Hz)
