Contract Opportunity

The Government is conducting market research with the intent to procure, under only one responsible source, where no other suppliers or service will satisfy the agency requirements. The Naval Facilities Engineering Systems Command, Hawaii (NAVFAC Hawaii) is conducting market research to determine if other potential products/services can provide for a Programmable Logic Controller (PLC) and Input/Output (I/O) Module that has the equal performance and listing/approval requirements as the RUG 9 Programmable Logic Controller (PLC) and R9 Input/Output (I/O) Modules, manufactured by Rugid, 25587 Conifer Road, Conifer, CO, 80433. The alternate product/service must meet the following requirements/specifications:

1. Be compatible with the telemetry radios, cybersecurity and standardization requirements for the existing SCADA system.

2. Be able to integrate and communicate with existing SCADA system without additional hardware, drivers, or software added to the existing Human Machine Interface (HMI), PLCs and I/O modules.

The mounting rack backplane must provide the communications mechanism to fully integrate the individual modules located within the rack. Modules other than I/O modules must plug directly into the backplane. The use of wire connectors between modules will not be allowed except for expansion of the system to include multiple backplanes. The rack size must be as needed to hold the equipment necessary while performing the required control functions. The system configuration must allow for the removal and/or installation of modules under power.

6. Central Processing Unit (CPU) Module: The CPU module must be a self contained, microprocessor based unit that provides time of day, scanning, application program execution, storage of application programs, storage of numerical values related to the application process and logic, I/O bus traffic control, peripheral and external device communications and self diagnostics. The scan time must be 250 milliseconds or better including spare I/O channels. Powered by 24 VDC power supply. >8 MB of program RAM available; >64 MB system memory RAM available.

Must assign local time-stamps to changes within the IO in the event that communication is lost. Must possess Modbus Master and Slave capability.

7. Communications Module: The communications module must allow peer-to-peer communication with other PLCs and must allow the PLC to communicate with the central station, or workstation. The communication module must utilize the manufacturer's standard communication architecture and protocol, ethernet architecture and protocol or a combination of these. The communication module must allow programming of the PLC to be done locally through the use of a laptop computer or from the central station or remote workstation. Must be capable of interfacing with ethernet connection at a minimum of 100 MB/s.

8. Power Supply Module: One or more power supply modules must be provided as necessary to power other modules installed in the same cabinet. Power supply modules must plug directly into the backplane. Auxiliary power supplies may be used to supply power to remote cabinets or modules.

• The power supply module must monitor the incoming line voltage level and must provide over current and over voltage protection. If the voltage level is detected as being out of range the power supply module must continue to provide power for an adequate amount of time to allow for a safe and orderly shutdown. Power supply modules must be capable of withstanding a power loss for a minimum of 20 milliseconds while still remaining in operation and providing adequate power to all connected modules.


• Each power supply module must be provided with an on-off switch integral to the module. If the manufacturer's standard power supply module is not provided with an on-off switch, a miniature toggle type switch must be installed near the PLC and must be clearly labeled as to its function.


• Provide power supply modules with an indicating light which must be lit when the module is operating properly.

9. Input/Output (I/O) Modules: Modules must be self contained, microprocessor based units that provide an interface to field devices. The modules must be located in the same cabinet as the other PLC components. Each module must contain visual indication to display the on-off status of individual inputs or outputs. Each I/O must be protected against reversal of polarity of the signal. Analog inputs and analog outputs must have 'open, short and out of range circuit' detection. It must be configurable per channel. Capable of operating in 10 to 95 percent relative humidity. I/O must be solid state with status indicating lights. Refer to IP20 for required degree of protection. Incorporate noise suppression design where applicable.

10. Program Storage/Memory Requirements: The CPU must utilize the manufacturer's standard non-volatile memory for the operating system. The controller must have electronically readable and writeable non volatile memory (EPROM, EEPROM, or Flash PROM) for storage of user programs. The user programs must be loaded through the controller keypad, central station or through the use of a laptop computer. The CPU memory capacity must be based on the system's control requirements. The memory capacity must be sized such that, when the system is completely programmed and functional, no more than 50 percent of the memory allocated for these purposes is used.

If the controller is not provided with a manufacturer's standard on-off switch, a miniature toggle type switch must be installed in the control panel near the controller and must be clearly labeled as to its function.

19. Diagnostics: Each PLC must have diagnostic routines implemented in firmware. The CPU must continuously perform self-diagnostic routines that will provide information on the configuration and status of the CPU, memory, communications and input/output. The diagnostic routines must be regularly performed during normal system operation. A portion of the scan time of the controller must be dedicated to performing these housekeeping functions. In addition, a more extensive diagnostic routine must be performed at power up and during normal system shutdown. The CPU must log input/output and system faults in fault tables which must be accessible for display. When a fault affects input/output or communications modules the CPU must shut down only the hardware affected and continue operation by utilizing the healthy system components. All faults must be annunciated at the PLC and the central station. Diagnostic software must be useable in conjunction with the portable tester. The following diagnostics must be performed:
