Arguments • baud_rate
1200, 2400,4800, 9600,19200, 38400
• data_bits
7, 8
• stop_bits
1, 2
• parity
0 = None; 1 = Odd; 2 = Even.
• port_number
See the table below.
port_number value Description
1 RS-232C serial port 1
2 RS-422A/485 serial port 2
• mode
Select one of the modes listed in the table below for serial ports 1 and 2.
Mode Description
0 General-purpose communication (no XON/XOFF mechanism)
4 ModbusRTU Slave Protocol (transfer as 16-bit integers)
5 Host Link Slave protocol
6 Host Link Master protocol
7 ModbusRTU Slave Protocol (transfer as 32-bit IEEE floating pointer)
• data_config
0 = Transfer of VR memory as Modbus registers.
1 = Transfer of TABLE memory as Modbus register.
• comms_timeout
Timeout for ModbusRTU communication (defaults to 4ms).
Example SETCOM(19200, 7, 2, 2, 1, 6)
This sets RS-232C port to 19200 baud rate, 7 data bits, 2 stop bits, even par-
ity for communication as a Host Link Master.

Type Mathematical function
Syntax SGN(expression)
Description The SGN function returns the sign of a number. It returns value 1 for positive
values (including 0) and value -1 for negative values.
Arguments • expression
Any valid BASIC expression.
Example >> PRINT SGN(-1.2)
-1.0000

Type Mathematical function
Syntax SIN(expression)
Description The SIN function returns the sine of the expression. Input values are in radi-
ans and may have any value. The result value will be in the range from -1 to
1.
Arguments • expression
Any valid BASIC expression.
Example >> PRINT SIN(PI/2)
1.0000
