ProLogic
ProLogic Control Statements
Using ProLogic, F-PRO can pick any of the protection functions or external in-
puts and place them into Boolean-like statements. ProLogic handles up to five
functions to generate one ProLogic statement; ten statements are possible. The
results from these statements are mapped to output contacts using the output
matrix.
Special ProLogic inputs are:
• Output relay #12 as an input to ProLogic.
The ProLogic control statements are used to create Boolean-like logic. The F-
PRO can use any of the protection functions or external inputs combined with
logic gates to create a ProLogic control statement. The possible gates are AND,
NAND, OR, NOR, XOR, NXOR, and LATCH. The control can be time delay
pickup and or time delay dropout, and can drive the front panel target LED.
Ten ProLogic control statements outputs are available and can be used in the
output matrix to customize the relay to your specific needs. Inputs to ProLogic
are all the elements plus previous ProLogic statements for logic nesting usage.
The example shows A to E inputs are status points of devices that are user-se-
lectable. Each ProLogic output can be given a specific name, pickup and reset
time delay.
