Functional Description
IC693CPU341 is a CPU Module developed by GE. It is part of the Mark I and II control system. The module is a central element in the GE Fanuc 90-30 Series of programmable logic controllers (PLCs). Known for its compact design and versatile functionality, this single-slot Central Processing Unit (CPU) module is equipped with five baseplates—one CPU baseplate and four additional baseplates that facilitate remote or expansion operations. This design allows for greater flexibility in system configuration and expansion, making it suitable for a variety of industrial automation applications. Powered by an 80C188XL processor, delivers reliable processing capabilities essential for controlling complex industrial processes.
Power Specifications
- The module is designed to operate efficiently under standard industrial power conditions. It runs at a frequency of 20 MHz, requiring a power load of 490 milliamps from a +5 VDC rated power supply. This low power consumption helps minimize operational costs while maintaining high performance.
- The module is capable of functioning in a diverse range of environmental conditions, with an operational ambient temperature range of 0 to 60 degrees Celsius (or 32 to 140 degrees Fahrenheit). This temperature range ensures the module remains reliable in various industrial settings, from climate-controlled environments to more extreme conditions.
Memory Configuration
Memory plays a crucial role in the functionality. With a typical scan rate of 0.3 milliseconds per 1K of logic—often referred to as Boolean contacts—the module is capable of processing data quickly and efficiently. It boasts a maximum user program memory of 80K bytes, providing ample space for complex programming needs.
The distribution of memory is as follows:
- Register Memory (%R): 9999 words, allowing for a significant number of data variables.
- Discrete Global Memory (%G): 1280 bits, facilitating a broad range of discrete I/O operations.
- Internal Coils (%M): 1024 bits, providing memory for internal processing and state tracking.
- Output (Temporary) Coils (%T): 256 bits, which are used for temporary storage of output states.
- System Status References (%S): 128 bits, split among various references (%S, %SA, %SB, %SC) to monitor system health and status.
I/O Capabilities
The module is equipped with extensive input/output (I/O) capabilities, allowing it to interface with a wide variety of field devices. These I/O specifications include:
- Analog Inputs (%AI): 1024 words, enabling the processing of numerous analog signals from sensors and other devices.
- Analog Outputs (%AQ): 256 words, which can send signals to actuators and other output devices.
- Discrete Inputs (%I): 512, allowing the module to read a large number of digital signals.
- Discrete Outputs (%Q): 512, enabling control over numerous digital devices.
- System Registers (%SR): 16 words, dedicated to reference table viewing and not referenced in user logic programs, ensuring clarity in data management.
- This robust I/O configuration not only supports traditional automation needs but also enhances the module’s adaptability for specialized applications, making it suitable for diverse industries such as manufacturing, energy, and transportation.
Product Attributes
- One of the standout features of the module is its built-in serial port, which facilitates seamless communication with external devices and systems. This port requires a connector to the PLC power supply used within the overall system and supports SNP/SNP-X slave protocols.
- This enables effective data exchange and control commands between the module and other components.
- Offers PCM/CCM compatibility, which enhances its connectivity with other modules and allows for flexible system configurations. However, it is important to note that to enable SNP/SNP-X master support, as well as CCM or RTU slave capabilities, a CMM module is required.
- For those needing RTU master functions, a PCM module must be integrated as well. This modular approach allows users to tailor their systems according to specific application requirements, enhancing overall functionality.
Local Area Network (LAN) Support
- In today’s industrial environments, connectivity is essential, and excels in this area with its Local Area Network (LAN) feature. This capability allows the module to support a wide array of option modules, including FIP (Fieldbus Interface Protocol), Profibus, multidrop configurations, Ethernet, and various controllers such as GBC (General Bus Controller) and GMC (General Motor Controller).
- The inclusion of LAN support not only enhances communication but also facilitates integration with advanced automation systems. This is particularly valuable in complex industrial setups where multiple devices must communicate efficiently and reliably. The ability to connect to multiple option modules enhances the flexibility, allowing it to be easily adapted to meet the specific needs of different applications.
Memory Storage Options
- Earlier iterations of the module included both RAM and optional EPROM or EEPROM for memory storage, which provided users with options for data retention and program storage. However, newer versions, beginning with hardware version 341-J and firmware Release 4.61, have streamlined their memory capabilities to focus on RAM with optional Flash memory for additional storage needs.
- This evolution reflects advancements in technology and the increasing demand for efficient, high-capacity memory solutions in modern automation applications. The shift to RAM and Flash allows for faster data access and improved overall system performance.
