Profinet / EtherNet/IP Deterministic Networks & Firmware Flash Compatibility
The IC693CPU374-GS leverages a dual-processor architecture where an integrated 200 MHz Ethernet processor offloads industrial network traffic from the core 133 MHz logic execution engine. While native to Series 90-30 architectures, this embedded switch design facilitates interface conversion routines for connection to modern Profinet / EtherNet/IP deterministic networks via external gateways or network interfaces.
Maintaining stable cycle times during periodic data exchange requires verification of firmware flash compatibility across all backplane elements. Mismatched firmware revisions between the CPU runtime environment and legacy Option Modules can degrade the backplane bus communication velocity, resulting in configuration synchronization errors or timed-out diagnostic polling sequences.
Frequently Asked Questions
Q: Does the IC693CPU374-GS support hot-swapping or run-time module extraction?
A: No. The Series 90-30 backplane design does not incorporate the electrical isolation circuitry necessary for hot insertion or removal. The main rack power supply must be completely de-energized before removing or seating the CPU module to prevent memory corruption and potential electronic damage.
Q: How is data loss prevented in the user logic area during an unpowered state?
A: The module relies on a front-accessible lithium battery to maintain the volatile SRAM contents. When the battery voltage drops below the safe operating limit, the CPU logs a specific diagnostic fault code, indicating that the program logic and retentive data registers will be erased upon the next power cycle if the cell is not replaced.
Q: What is the physical behavior of the two integrated RJ45 network ports?
A: The two ports are linked via an embedded Ethernet switch layer. They share a single IP address and MAC address, functioning as a regular pass-through hub to allow linear daisy-chain wiring layouts without necessitating an external standalone switch module.
Field Installation Guidelines
- Chassis Engagement: Ensure main supply power to the baseplate is disconnected. Align the module housing with the specific processor slot guides on the far left of the Series 90-30 rack, swing the unit down until the rear hooks seat completely, and verify the mechanical retention latch clicks into position.
- Shielding Ground Base: Use only shielded twisted-pair (STP) cables for all Ethernet connections. Ensure the outer foil shield of the cable makes direct, unbroken physical connection with the metal shroud of the RJ45 port to route high-frequency noise to the frame ground.
- Serial Comm Separations: Route the RS-232 and RS-485 lines through low-voltage cable ducts segregated from high-power AC distribution cabling and motor drive lines to minimize electromagnetic cross-talk.
- Thermal Convection: Mount the rack assembly horizontally inside an IP20 or better enclosure, maintaining at least 50 mm of free air space above, below, and around the module housing to allow passive thermal dissipation.
