XQ _ED3,_ED1,1	Skip invalid command
ENDIF
EN	End of command error routine

Example – Ethernet Communication Error

This simple program executes in the DMC-3425 and indicates (via the serial port) when a communication handle fails. By monitoring the serial port, the user can re-establish communication if needed.

Mathematical Operators

For manipulation of data, the DMC-3425 provides the use of the following mathematical operators:

Operator	Function
+	Addition
-	Subtraction
*	Multiplication
/	Division
&	Logical And (Bit-wise)
	Logical Or (On some computers, a solid vertical line
	appears as a broken line)
()	Parenthesis

The numeric range for addition, subtraction and multiplication operations is +/-2,147,483,647.9999. The precision for division is 1/65,000.

Mathematical operations are executed from left to right. Calculations within parentheses have precedence.

SPEED=7.5*V1/2	The variable, SPEED, is equal to 7.5 multiplied by V1 and
	divided by 2
COUNT=COUNT+2	The variable, COUNT, is equal to the current value plus 2.
RESULT=_TPA-(@COS[45]*40)	Puts the position of A - 28.28 in RESULT. 40 * cosine of
	45° is 28.28
TEMP=@IN[1]&@IN[2]	TEMP is equal to 1 only if Input 1 and Input 2 are high
