- Cooling and Installation: To ensure optimal performance and reliability, mounted horizontally and installed within a protective enclosure with an IP54 rating or higher. It is considered open equipment, and a minimum space of 4 inches is required around all sides for proper heat dissipation.
- Terminal Strip: Located on the left side, the terminal strip is used for connecting isolated +24 Volts DC input voltage, facilitating power connections to the backplane.
- Slot Identification: Slot numbers are printed on the backplane for easy identification, simplifying module installation and configuration.
Slot Configuration
- Slot 0: Reserved for the backplane connector of the power supplies.
- Slots 1 through 11: Can accommodate PCI and serial bus compatible modules.
- Slot 12: Designed for connecting RX3i serial expansion modules.
RX3i Universal Backplane Installation Guidelines
The installation of the RX3i system and its components must adhere to specific safety and performance standards due to their classification as open equipment, which means they contain live electrical parts that may be accessible to users. Below are key installation requirements and considerations:
Protective Enclosure Requirements
To ensure user safety, the RX3i system must be housed within a protective enclosure or incorporated into assemblies designed to provide adequate safety measures. The enclosure or assemblies must, at a minimum, meet the following protection standards:
- NEMA/UL Type 1 Enclosure: This standard ensures basic protection against limited access to electrical parts.
- IP20 Rating (IEC60529): This rating indicates protection against solid objects greater than 12mm and no protection against water.
- These enclosures must effectively protect users from potential electrical hazards while allowing the system to function optimally.
Heat Dissipation Considerations
Heat management is critical for the longevity and performance of the RX3i components. The enclosure must be designed to facilitate adequate heat dissipation from all mounted components to prevent overheating. Key guidelines for heat management include:
- Minimum Clearance: Ensure a minimum space of at least 102mm (4 inches) is maintained on all sides of the RX3i backplane. This clearance is essential for proper airflow and cooling.
- Additional Space: Depending on the specific heat output of the equipment during operation, additional space may be necessary to enhance cooling efficiency.
Backplane Orientation
Proper mounting orientation of the RX3i backplane is essential for optimal system performance and reliability. It is strongly recommended that backplanes be installed in a horizontal position. This orientation:
- Ensures Adequate Airflow: A horizontal mounting setup promotes effective airflow around the modules, which is vital for cooling.
- Prevents Performance Issues: Alternative mounting orientations may disrupt airflow and lead to potential overheating, adversely affecting system reliability and performance.
- By adhering to these installation guidelines, users can ensure the RX3i system operates safely and efficiently while minimizing the risk of component failure due to overheating or inadequate protection.
Module Locations in a Universal Backplane
- When configuring a Universal Backplane for the RX3i system, understanding the appropriate placement of various modules is crucial for optimal operation and functionality. Below are detailed guidelines regarding module locations within the backplane.
- The Universal Backplane accommodates various power supply modules with specific placement rules. IC695 power supply modules can be installed in any slot within the backplane. Specifically, DC power supplies (IC695PSDx40) occupy one slot each, while AC power supplies (IC695PSAx40) require two slots. It's important to note that IC694 and IC693 power supplies are not compatible with Universal Backplanes and therefore cannot be installed.
- The installation of I/O and option modules follows certain guidelines to ensure proper functionality. I/O and option modules can be installed in any available slot, with the exception of slot 0, which is exclusively reserved for IC695 power supplies, and the designated Expansion slot. Each I/O slot features two connectors, allowing for the installation of either an RX3i PCI-based module or a serial module.
- The rightmost slot in the backplane is designated as the Expansion slot, reserved solely for the optional serial expansion module (IC695LRE001). This module allows for enhanced connectivity and communication capabilities.
- The RX3i CPU is versatile in terms of installation location, but there are important considerations. An RX3i CPU can be installed in any slot except the Expansion slot, and it occupies two slots in total. If the CPU is installed in slot 1, only a single-width power supply can be utilized in slot 0. It is permissible to use either DC power supply in this configuration. If the application necessitates maintaining a CPU in slot 1 while also using an AC power supply, the AC power supply must be positioned in a slot to the right of the RX3i CPU in slot 1.
- When deciding on the placement of the CPU in a slot other than slot 1, several important factors must be taken into account. The configured slot location of the CPU must accurately reflect its true physical location within the backplane to ensure proper system operation. For Service Request #15 (Read Last-Logged Fault Table Entry) and Service Request #20 (Read Fault Tables), the location of any CPU faults is determined by the slot the CPU occupies. This may necessitate updates to any logic that decodes fault table entries retrieved through these service requests.
- When using COMMREQs directed at the CPU itself, it is essential to utilize the correct CPU slot reference to ensure successful communication. Additionally, any external devices connected to the RX3i system should be checked for compatibility with CPU slot locations other than slot 1 to prevent operational issues. For Remote Series 90 PLCs utilizing SRTP Channels, it is crucial that COMMREQs expect the CPU to be located in slot 1 or slot 2 for seamless communication and functionality.
