Xycom XVME-201 is a digital input/output module based on the VMEbus architecture. Its core function is to provide 48 bit digital I/O channels, suitable for data acquisition and equipment control in industrial automation. However, it is not a traditional PLC module, but a dedicated controller based on VMEbus.

Core functions and technical parameters

Digital I/O channel

Integrate 2 68230 PI/T chips, provide 48 bit digital I/O (specific allocation needs to refer to the manual), support TTL level signals, suitable for connecting switches, sensors, actuators and other devices.

User programmable timer: The PI/T chip has a built-in timer function that can be used to generate precise time delays or periodic signals.

VMEbus interface

Supports VMEbus short I/O space addressing and can be seamlessly integrated with other VMEbus modules such as processors and communication modules.

The module address is configured through the X201Base parameter and needs to be consistent with the system backplane settings.

Limitations and Precautions

Non interrupt function: XVME-201 cannot actively trigger interrupts and needs to read I/O status through polling.

Parameter matching requirements: The parameters in the driver program (such as chip number, register address) must be strictly consistent with the hardware definition, otherwise it may cause abnormal operation.

Typical application scenarios

Industrial Automation

As an extended I/O module of PLC, it connects field devices (such as limit switches and solenoid valves) to achieve logical control.

Example: In the assembly line, XVME-201 is used to read sensor signals and control cylinder movements.

test and measurement

Used for data acquisition systems to synchronously read multiple digital signals (such as speed pulses, fault flags).

Example: In vibration testing, the pulse interval is accurately measured through the timer function.

Energy and Transportation

Collecting the status of circuit breakers in power monitoring or for signal control in rail transit.

technical advantage

High reliability design

The VMEbus architecture has anti electromagnetic interference and redundant communication capabilities, making it suitable for long-term operation in industrial environments.

TTL buffer circuit protects I/O ports from overvoltage damage.

Flexible configuration options

Set the port direction (input/output) through software to adapt to different application requirements.

Support multi module cascading and expand the number of I/O channels.

Market positioning and competitive analysis

Brand background: Xycom (now Emerson) is a leader in VMEbus technology, known for its high performance and reliability in its products.

Competitive advantage:

Compared to general-purpose I/O modules, XVME-201 has more advantages in terms of VMEbus compatibility and real-time performance.

Modular design facilitates system upgrades and maintenance.
