Serial I/O: MPC860P Serial Interface

General Purpose Timers

The general purpose timers can be configured as four 16-bit or two 32-bit identical timers.

The best resolution of the time is one clock cycle, which translates to 25 nanoseconds at 40

MHz. The maximum period is 268,435,456 cycles, translating to 6.7 seconds at 40 MHz.

Independent DMA (IDMA) Channels

The MPC860P has two IDMA channels which may be programmed by the user to transfer data between any combination of memory and I/O. The IDMA supports 32-bit data and addressing, dual or single address modes, and three buffer modes (single, auto, and buffer chaining). The theoretical maximum data rate of the IDMA with a local bus speed of 25 MHz is 50 MB/second.

Serial DMA (SDMA) Channels

The MPC860P has fourteen SDMA channels dedicated to the transmit/receive channels of the serial controllers. Data from the serial controllers may be routed either to external RAM or to internal dual-port RAM. When transfers use the internal dual-port RAM, other opera- tions may occur simultaneously on the PmT1 and PmE1 local bus.

MPC860P SERIAL INTERFACE

Several types of popular serial protocols are available on the PmT1 and PmE1. Please refer to the MPC860 PowerQUICC™ User's Manual for more detail on these supported protocols.

UART: The universal asynchronous receiver transmitter protocol is the defacto standard for com- municating low-speed data between equipment. The most popular of these is the EIA-232 standard. EIA-232 specifies standard baud rates, handshaking protocols, and mechani- cal/electrical details. Other popular standards include EIA-422 and EIA-485, which offer fea- tures such as longer line lengths and multidrop support.

The UART also supports synchronous mode, where a clock is provided with each bit. Syn- chronous UART mode can provide faster data transfers, because there is no need to over- sample the data bits.

HDLC: HDLC is one of the most common layer 2 protocols (of the seven-layer OSI model). HDLC protocol consists of a framing structure which is synchronously transferred. Therefore, HDLC relies on the physical layer (i.e., SI with TSA) to provide a method of clocking and syn- chronizing the transmitter/receiver. Each of the four SCCs can function as an HDLC control- ler. The SCC outputs can then be routed directly to the external pins, or connected to one of two TDM channels via the TSA.

PMT1, PME1 specifications

The Emerson PME1 and PMT1 are advanced solutions in the realm of process management and automation, designed to enhance the efficiency and effectiveness of industrial operations. These devices play a crucial role in improving process control and providing comprehensive data analysis, which can lead to increased productivity and reduced operational costs.

The PME1 is characterized by its robust design and highly flexible architecture, allowing it to adapt to a variety of industrial environments. It integrates seamlessly with existing systems and offers advanced connectivity options to ensure that data flow is uninterrupted across different platforms. This feature is particularly important in modern industrial settings where data silos can inhibit operational efficiency.

The PMT1, on the other hand, focuses on real-time monitoring and telemetry. Its streamlined interface allows for quick access to key metrics, enabling operators to make informed decisions promptly. This is crucial in processes where timing is essential and minor delays can lead to significant financial losses. The PMT1 supports both wired and wireless communication protocols, ensuring that data is transmitted reliably irrespective of operational conditions.

One of the main features of both the PME1 and PMT1 is their integration of cutting-edge predictive analytics. With machine learning capabilities, these devices can analyze patterns and trends within the data, providing insights that can preemptively address potential issues before they escalate into significant problems. This predictive capability contributes to minimizing downtime and optimizing maintenance schedules, thus enhancing the overall lifecycle of equipment.

Another significant characteristic of the PME1 and PMT1 is their user-friendly interface. The intuitive design allows operators of all skill levels to navigate the systems with ease, minimizing training time and increasing overall productivity. With customizable dashboards, users can tailor their views to highlight the most relevant data for their specific operational needs.

In terms of security, both devices utilize advanced cybersecurity measures to protect sensitive data from unauthorized access. This is becoming increasingly important as industries rely more on digital solutions, and the potential risks associated with data breaches grow.

In summary, the Emerson PME1 and PMT1 are sophisticated tools designed for modern industrial applications, combining powerful features, advanced technologies, and essential characteristics. Their ability to provide real-time data analysis, ensure connectivity, and enhance predictive maintenance makes them invaluable for optimizing process management in various sectors. With a focus on user experience and data security, these devices are set to redefine efficiency and productivity in industrial operations.
