Local Logic Language Syntax

GFK-1742A Chapter 12 Local Logic Language Syntax 12-11

Operator MOD

The MOD operator returns the remainder resulting from the signed integer division of

source1 by source2. A double precision (64-bit) parameter register may be used as the

numerator.

Syntax

destination := source1 MOD source2;

Syntax

destination := double source1 MOD source2;

The MOD operator syntax has these parts:

Part Description

Destination Any writeable local logic variable except Dxx registers.

source1 Any readable local logic variable or numeric constant.

double source1 Any of the 64-bit local logic parameter variables (Dxx registers).

source2 Any readable local logic variable/constant except Dxx registers.

Overflow

- See

remarks

below.

Remarks

In case of a divide by zero, the Module_Status_Code is set to 16#2093. In case of a

divide overflow, the Module_Status_Code is set to 16#2094.

The modulus (remainder) is calculated by performing an integer division, therefore the

MOD operator has the same error conditions as the divide operator.

A divide overflow occurs when the quotient of a divide operation cannot be correctly be

represented as a signed 32-bit value. This can only occur when using a double operand

as the numerator. A divide by zero occurs when the denominator of the divide has a

value of zero.

A divide overflow or divide by zero are Stop Fast errors. Local Logic is immediately

aborted and motion is aborted by setting the servo velocity command to zero.
