Geq (GReATeR THAN OR eqUAL)
This instruction will test to see if Source A is greater than or equal to Source B. If Source A is
greater than or equal to Source B then the rung is evaluated as true, otherwise the rung is false.
Source A must be an address. Source B can either be a program constant (integer only) or an
address.
The GEQ instruction executes in 15µs and requires 44 bytes.
Following is a list of the data points that may be used with GEQ instructions:

Timers (preset & value)
Counters (preset & value)

Alarms
math Instructions
The SCADA 3000 incorporates basic math instructions including: add, subtract, multiply,
divide and power. These instructions will take two input values, perform the specified arithme-
tic function, and output the result to the specified address location.
ADD (Addition)
The ADD instruction adds the values stored in the two referenced memory locations, labeled
as Source A and Source B when rung conditions are true. The result is stored in the destina-
tion memory location. The operand values can be fixed constants, values contained in I/O, or
variables stored in any memory location. Only one constant can be used—in Source A or B.
The ADD instruction executes in 15µs and requires 68 bytes.
