Product Description
With its powerful architecture and industrial-grade hardware, PG5901B provides seamless protocol conversion for devices in industrial network operations. With its rugged construction, PG5901B is designed to perform in the most demanding of industries – including power distribution, oil and gas, manufacturing, and agriculture. As a highly reliable and fault-tolerant Industrial Protocol Gateway, also features integrated 3G/4G connectivity, making it ideal for any industry looking to implement devices at remote locations for smart grid operations. Serial reach can also be extended with the Gateway’s redundant Ethernet.

Performance
Its rugged, reliable hardware features high EMC protection, wide temperature operation, and programming and installation flexibility in one device, while its advanced performance protects your data over the Internet with secure IPsec VPN or OpenVPN tunnels, with its powerful CPU providing up to 37.9Mbps* software-assisted AES encryption.

Configuration
The device can be easily configured using eNode Designer, a user-friendly Windows utility based on Java. The tool allows users to assign various protocols to different ports, define serial port settings, and define protocol-specific parameters, such as data point mapping. eNode uses a project file to represent the system as a whole, with eNode modules representing individual network devices and protocol applications for individual configuration – such as defining where data point information enters and leaves the eNode Designer system.

Application

The protocol gateway’s embedded protocol stacks allow:
– Seamless conversion
– Exception/error Management
– Unsolicited event management for the protocols requiring them (such as DNP3)
– High performance
– Low cost

In this example, a Modbus Serial HMI is easily connected to a DNP3 IED through Atop’s Protocol Gateway. The host HMI’s role is a Modbus Serial Master while the end-device to be accessed is a DNP3.0 Ethernet Server Slave. To the host HMI, Atop’s Protocol Gateway acts seamlessly as a Modbus Serial Slave, answering the polling commands and write commands that come from the by using a virtual Modbus ID. Simultaneously, Atop’s Protocol Gateway acts as a DNP3 Ethernet Client to any end-device whose DNP3 address is mapped to the virtual Modbus ID that the HMI is accessing.

WARNING

All gateway functions listed in the datasheet refer to the “Gateway” role, and not which “host” or “slave” the gateway is connected to. The SKU shown in this example is “MBSS-DNEC” (Modbus Serial Slave to DNP3.0 Ethernet Client).
