The Black Fabric® communication consists of galvanically isolated, full-duplex communication channels. One or two channels are dedicated to the SPM modules while the remaining channels are dedicated to SIO modules. The number of channels available for controllers, SPMs, and I/O modules is dependent upon the BMI and Controller Type.

Each SIO module has the connections to a Controller. Each SIO module has a dedicated full-duplex four-wire bus connecting the Controllers and SIO modules. This allows a Controller to receive SIO data directly into its registers.

The entire system works as a large heat sink. A typical controller will release its heat using convection out of vents. The Bedrock controller uses conduction to pull heat from the components. The module cases act as heatsinks, which allow the boards to run at uniform temperatures, eliminating hotspots, and prolonging the life of the boards.

The storage temperature and humidity of the hardware is -40°C to 85°C and 5% to 95% non-condensing humidity.

The operating temperature is dependent upon the BMI type and type of power supplied to a single SPM. The operating temperatures are summarized:

NOTE: The maximum operating temperature for SIO4.E and UCG.5 modules when using PoE is 70°C. The maximum operating temperature for SIO4.E and UCG.5 modules when not using PoE is 80°C.

*The SPS input voltage range is 85 to 264 VAC

All Bedrock Controllers have configurable magneto resistive RAM (MRAM) available, up to 252 kB. This allows control programs to have access for storage and retrieval of persistent or retained variables. The values of persistent and retained variables persist during power cycles without the need of an energy storage device (i.e. PLC battery).

The minimum scan period is 3ms

The UCG and 4.E are both modules used for Ethernet communication. The 4.E is limited to Modbus TCP, EtherNet/IP, and communication with the UPS/SPS. The UCG can do everything the 4.E can plus acts as an OPC UA server and can run Codesys applications. The UCG also contains 128 MB of RAM and 252 KB of MRAM.

Yes, the I/O modules are hot swappable.

The BMI.10 and BMI.20 both have the option of redundant power, control, and I/O when using SCCs

Additional BMIs can be added to a system and peer to peer communication can be established between controllers.

The OSA Remote is designed to provide remote applications with power, control, and I/O in a single transportable unit that can be configured and programmed on a desktop and then mounted at a remote location. Each OSA Remote provides either ten or twenty universal, secure input/output channels, in addition, to support for serial and Ethernet I/O.

Secure Control and Communication (SCC) Controllers support up to twenty SIO modules, provide a second Ethernet port, and offer Controller redundancy. Redundant power is also supported.

Secure Controller Single (SCS) Controllers are available in the two models described below. Redundant Controllers are not supported by either model.

• SCS.10 Controllers support up to ten SIO modules
• SCS.5 Controllers support up to five SIO modules
• Redundant power is supported for SCS Controllers when mounted on a BMI.10 or BMI.20

When initially designing a system, use BMI.10 or BMI.20 backplanes. This will ensure that CPU redundancy can be achieved by simply adding an SCC to slot 2 of the BMI. Competing automation manufactures need more than one backplane to implement redundancy, where Bedrock accomplishes it with just one.

Being the chip manufacturer does not allow for faster returns or replacements, that would depend on the inventory maintained at Bedrock. However, it does allow us to ensure the non-obsolescence of our products.

The Backplane Magnetic Interconnect (BMI) is Bedrock’s passive backplane, which provides mechanical support and electrical connection for the controller, SPM, and SIO modules. Any combination of SIO modules can be installed in slots 1 through 5, 10, or 20 (depending on the model). The orientation of the SIO modules does not matter and modules can be flipped to make wiring easier. However, the slots/orientation for the controllers and power modules are fixed.

Both the SPS and UPS were designed with the intent of being mounted externally to the control enclosure. Both units are compliant with IP66/67 (dust tight, protection against water jets, and immersion) and NEMA ratings 4, 5, and 6 (watertight, dust tight, and immersible). Options for mounting include pipe or panel.

When utilizing the SPS and UPS with an SPM.U (universal BMI power module), wiring can be done to allow the ability of taking either the SPS or UPS offline for maintenance purposes without affecting the BMI and its’ modules. The UPS does not require battery maintenance and the life expectancy of the UPS is 25+ years.

Yes, the SPS and or UPS can complement any PLC or DCS and provide a reliable cybersecure power solution.

Configuration parameters for the both the SPS and UPS are accessed via the Device Management Tool in the Bedrock IDE software. The Device Management Tool is also where the SPS and UPS network configuration is located.

Any HMI or SCADA software that supports OPC UA will be able to monitor any and all diagnostic values from the SPS and UPS.

Yes. Both units ship with a default configuration.

Bedrock has an embedded web server for visualizations and works with any HMI that supports the OPC UA, MQTT, Modbus, or EtherNet/IP protocols.

The IEC 61131-3 programming languages are five standard programming languages for both process and discrete controllers. The following languages are all supported in the Bedrock IDE:

• Ladder Diagram (LD)
• Sequential Function Chart (SFC)
• Structured Text (ST)
• Function Block Diagram (FBD)
• Continuous Function Chart (CFC)

Modbus TCP, Modbus RTU, EtherNet/IP, and HART

Data Sources Manager allows communication to be established to remote devices

Bedrock does maintain a library of useful tools, which gets released and updated with the IDE or included in a service pack update. Custom libraries can be created and maintained with the Bedrock IDE

Yes, libraries from the Codesys Store, such as the OSCAT Basic Library can be added and used in program in the Bedrock IDE.

Each I/O Module has different parameters/options that can be configured via the Bedrock IDE. These options are dependent on the module type. In general, the input/output type, failsafe mode, etc. can be configured per I/O point with the Bedrock IDE. There are no hardware defining physical switches on any of the modules or controllers, everything is defined within the application.

.X Certificates are Transport Layer Security (TLS) X.509 certificates and can be used to further limit unauthorized access to the Bedrock Control System. The .X security option enables an organization to manage a family of certificates for its users and devices based on its own unique root of trust.  Access to and operation of OSA system devices then requires these custom certificates.  All other access is denied.

Public Key Infrastructure (PKI) is a technology for authenticating users and devices in the digital world. It also provides the mechanisms for managing secure encrypted communications. It is the technology that enables secure Internet commerce. The basic idea is to have one or more trusted parties digitally sign documents certifying that a particular cryptographic key belongs to a particular user or device.

Bedrock keys and certificates are managed by a special high security computer called a DLM.  Users of .X certificates manage their certificates using a cloud-based interface.  The DLM is FIPS 140-2 Level 3 certified.

Secure boot is the process that ensures that a device is running the correct software.  It requires microprocessor with special features.  Execution starts with software on the processor chip.  The rest of the software is encrypted and signed.  The decryption keys are stored in special hidden registers.  Software updates are also encrypted and signed to ensure they can come only from Bedrock.

No. The Bedrock system is a high performance control system and security is designed in to ensure that it does not affect system speed and performance.

Physical tamper protection that is designed for compliance with FIPS 140-2 Level 2 (SPMs, SIO modules, and Controllers)
