when any company going to install new instrument control
system,they have to test how its working ? In the FAT shop
they will do configuration setting for all instrumet loops.
according to configuration the system providor will do
function test by simulating signals.

but during the SAT they will check all function with real
Input signals.

Answer / ajay

FAT: it is the acronym of Factory acceptance test i.e.
Tests performed under simulated conditions at
manufacturer's place witnessed by approving authority
client/End user.
FAT is performed to check the correctness of the system
being supplied. FAT covers all checks over hardware,
interfaces, logics & control loops and system configuration
as per the procedure defined in FAT document.
FAT is performed for Control/DCS & PLC panels.

SAT: it is the acronym of Site acceptance test i.e. tests
performed under live signals received from instruments
installed in plant during the actual commissioning of the
system at site/ end user's place. During SAT, all live
signals are checked and individual control loops & logics
are performed accordingly.
Once all individual loops and logics are checked, then only
plants process is left to run through control system itself.

Answer / gnb

FAT: It will be conducted at System Supplier's place with
presence of EPC and End user.They will check the
functionality of Control loops and logics with use of
Simulators.Third part devices will also physically
connected to the system supplier and functionality will be
checked and corrected.

SAT: It will be conducted at End user's place.Here field to
system will be checked and corrected.
