Source A > Source B
The GRT instruction is used to test whether one values is greater than another. If source A is
greater than the value at source B, the instruction is logically true. If the value at source A is less
than or equal to the value at source B, the intruction is logically false.
The symbol for the greater than command is illustrated above. The GRT command is placed on
the left side of the rung to determine if a rung will be true or false for an output command. There
are two parameters to enter Source A and Source B:
Source A - must be a Address.
Source B - can be either a program constant or an address. Negative integers are stored in
two's
complemntary form.
