MCP-4 Compatibility

The MCP-4 has a dual-channel (four-wire) E-Stop circuit where the switch contacts are in parallel. This is different from the MCP III where the switch contacts are in series. This difference affects how the MCP-4 is used in various Adept systems. Table C-1covers the compatibility status for the MCP-4.

	Table C-1. MCP-4 Compatibility Guidelines

In Adept systems rated for Category 1 Safety

In MV Controller-based		MCP-4 is compatible, no issues
systems with CIP2, CIP1, or
VFP

In SmartController-based		In systems that are shipped from the factory with an MCP-4, there are
systems		no compatibility issues.
		If you are installing an MCP-4 in a system that originally used an MCP
		III, then Adept recommends removing 10356-10370, CIM TO MCPIII
		Adapter for reliability, but not for compliance reasons.

In Adept systems rated for Category 3 Safety (CE: Redundant Channel, RIA: Control Reliable)

In MV Controller-based		To maintain a dual contact enable in CE Category 3 Emergency Stop
systems with CIP2 or CIP1		systems, remove jumper JP3 inside CIP.

In MV Controller-based		MCP-4 not compatible. Cannot maintain a dual contact enable with the
systems with VFP3		MCP-4, must use MCP III.

In SmartController-based		In systems that are shipped from the factory with an MCP-4, there are
systems		no compatibility issues.
		If you are installing an MCP-4 in a system that originally used an MCP
		III, then you must remove 10356-10370, CIM TO MCPIII Adapter. This
		must be done for compliance reasons in order to maintain a dual
		contact enable in CE Category 3 Emergency Stop systems.

127 RS-422/485, XSYS, XUSR, RS-232/TERM specifications

Nortech Systems offers a comprehensive suite of serial communication solutions, including RS-232/TERM, XUSR, XSYS, and RS-422/485 interfaces. These products are designed to facilitate reliable and high-speed data transmission in various industrial applications, making them essential for connecting devices in automation, telecommunications, and data acquisition systems.

The RS-232/TERM interface is a widely adopted standard for serial communication, known for its simplicity and robustness. It supports point-to-point communication over relatively short distances, typically up to 50 feet. Key features include a maximum baud rate of up to 115.2 kbps, error-checking capabilities, and a straightforward connection process, making it ideal for connecting peripheral devices like printers, modems, and barcode scanners.

Building on the RS-232 standard, the XUSR and XSYS devices offer enhanced functionalities and flexibility. XUSR, for instance, supports not just traditional RS-232 connections, but also protocol conversion for various serial interfaces, facilitating seamless integration of legacy systems with modern networking technologies. It is particularly useful in environments where multiple protocols need to be managed simultaneously.

XSYS is designed for more complex applications and supports advanced communication features such as multi-drop configurations, enabling it to connect multiple devices on a single bus. This makes it suitable for extensive industrial networks where space and wiring complexity need to be minimized. Synchronous and asynchronous data transfer modes ensure that the XSYS is adaptable for both real-time data collection and standard command-response applications.

On the other hand, RS-422/485 interfaces excel in long-distance communication, allowing for data transmission over distances up to 4,000 feet. They are designed for multi-point connections, supporting up to 32 devices on a single bus through differential signaling, which enhances noise immunity. These characteristics make RS-422/485 particularly well-suited for environments with electromagnetic interference, such as factories or subways.

Nortech Systems’ serial communication solutions emphasize reliability, ease of use, and versatility. With their commitment to high performance and user satisfaction, these interfaces provide critical connectivity in today’s increasingly automated and interconnected world. Whether in data centers, manufacturing setups, or remote sensor networks, Nortech's offerings stand out for their reliability, efficiency, and adaptability, ensuring effective data communication across diverse applications.
