2. Baggage Handling Control System:
3.
a. PLC system for Curbside System: The controls shall be designed to meet the
specific functional requirements of the BHS for operation and maintenance
information. The PLC shall have the ability to test the fire alarm and access
control interface functions. At a minimum, the system shall consist of the
following:
1) Programmable Logic Controllers (PLCs): The BHS shall utilize two (2)
fully redundant Programmable Logic Controllers in a Cold-Backup
configuration with an A/B switch. Remote I/O shall be in the Motor Control
Panel (MCP). The BHS logic controller shall accept all external inputs from
push-buttons, switches, and photocells, and act as the logic unit to control all
conveyor functions and operations as specified in this Specification Section,
as indicated on the drawings, and as required for a complete functional
operating system. The PLCs shall be installed in the Motor Control Panel
(MCP), as indicated on the drawings. The PLC shall be networked to the
PanelView via Ethernet TCP/IP, or approved equal data communications
link protocol. The PLC program shall control all operation functions, unless
specified otherwise. Power to inputs and outputs that must remain
operational during shut down due to E-Stop activation, circuit breaker trip,
overload trip, etc. shall not be interrupted or disconnected by the associated
occurrence, unless necessary for safety.
2) Redundancy: Equipment and components downstream of the PLCs are not
required to be redundant, unless noted otherwise or necessary for the
operation.
3) Software and Programming: The BHSC shall provide software and
hardware consistent with industry standards, and where necessary,
compatible with existing equipment.
a) Graphical User Interface (GUI): Graphical User Interface (GUI) shall
be user friendly. It shall be provided through a multi-tasking
operating system capable of controlling multiple programs at one
time. It shall incorporate object linking and embedding (OLE)
technology or similar, and shall comply with the requirements
identified herein and on the Contract Drawings.
b) Networking and Communications: Networking and Communications
shall be compatible with the data communication protocols and
provide fast interfacing performance between all
communication/control tiers. It shall comply with the requirements
identified herein and on the Contract Drawings.
4) Software Documentation: The BHSC shall provide latest commercially
available non-proprietary software wherever possible and applicable, unless
application requires customized programming. Beta software is not
acceptable. All software proprietary information shall be provided to the
Authority prior to Final Acceptance, but shall not indemnify the BHSC for
technical defects that occur with the software. Program source codes with
