SATS Food Industries

Further to a competitive tender exercise, SATS Catering Pte Ltd have awarded ASS Pte Ltd with a contract to upgrade the Programmable Logic Controllers (PLCs) and the RFID Tag Reading System associated with their Cart Transport System (CTS) at the SICC2 facility Changi, Singapore.

The existing Modicon 984 PLCs together with the associated 800 series I/O will be upgraded utilising the Modicon Quantum range of products. The existing system comprises 5 Modicon 984 CPUs and approx. 2000 I/O points. The upgrade allows for the existing Modbus Plus communications to be upgraded to TCP/IP.

The existing long range active RFID Tag Reading System will be upgraded to a short range passive system utilising the IDENT range of equipment as manufactured by Pepperl + Fuchs. There are 98 Tag Readers and 30 IDENT Decoders associated with the system.

The upgraded Tag Reading System will communicate to the PLCs via the TCP/IP protocol.

The overall upgrade will enable the entire CTS control system to communicate to the previously upgrade Cart Transport Management System (CTMS) via TCP/IP.

The project will be carried out in phases with an anticipated completion date of November 2014.
