WHAT IS CPC Gateway?
More Than Just a Custom Protocol Converter
A flexible device supporting about 100 protocols used to collect information from a myriad of devices that use multiple protocols over multiple ports and put all the information in a common format.
Our CPC Gateway™ is a custom protocol converter that works with a long list of protocols and devices to take any standard or proprietary protocol used in industrial communications and translate the data collected into a usable format for communication to maintenance or technical staff or for integration into an overall monitoring system. This genset and engine monitoring gateway can convert data messages, events and commands into the format that fits your needs.

CPC Gateway – Your Engine Monitoring Gateway
With a list of features that includes user configurable port settings and addresses, modular jacks to prevent wiring errors, and the ability to support over 100 protocols, including well known names such as Allen Bradley, GE Fanuc, Siemens, Modbus, BACnet, CANopen, Schneider, Ethernet IP and Honeywell, our custom protocol converter really does much more. It allows for a set-up that is simple and quick for any qualified technician with basic computer skills, and makes our engine monitoring Gateway stand out from its competitors through its flexibility, ease of use and capabilities.
Monico’s Custom Protocol Gateway is an extremely flexible device with four to six physical ports which can communicate in up to nine protocols simultaneously. It supports an average of 100 protocols, with more being added on a regular basis, and can be used to collect information from a myriad of devices which use multiple protocols over multiple ports and then put all the information in a common, pre-configured data map. It can be used to connect Allen Bradley, GE Fanuc, Siemens, and Schnieder PLC’s into one functional network as well as many other devices.

Custom Protocol Converter
We named this product CPC, or Custom Protocol Converter, because of our ability to custom configure it to pull the protocol your equipment uses and convert the pulled data into the protocol you want outputted to your specific monitoring system. Whereas the CDL Gateway and J1939 Gateway communicate through the primary output of CDL or J1939, this Gateway can collect information from an input other than CDL or CAN bus.

FAQs
Frequently Asked Questions
What is the CPC Gateway™ used for?
The CPC Gateway™ (Custom Protocol Converter) is a powerful, multi-protocol device that collects data from a wide variety of industrial equipment using different communication standards and unifies that data into a single, consistent format — ideal for engine and genset monitoring, as well as broader plant-wide integration.
What types of protocols and devices are supported?
The CPC Gateway™ supports a vast list of both standard and proprietary protocols. It can connect to PLCs, drives, sensors, and other industrial devices from manufacturers like GE Fanuc, Schneider, Siemens, Yaskawa, and many more. Protocols include CANopen, Ethernet IP, DeviceNet, ProfiBus, and Caterpillar® Data Link, among others.
Can I monitor engines and generator sets with this device?
Yes. While it’s broader than a single-brand solution like the CDL Gateway™, the CPC Gateway™ excels in multi-equipment environments where engines, gensets, and auxiliary systems must be monitored together using different protocols.
What’s the typical data polling speed?
The device pulls data at a rate of roughly 20–60 parameters per second, depending on the protocol and setup. This high throughput supports real-time monitoring of complex systems.
Can this gateway be used in multi-vendor environments?
Absolutely. It’s ideal for complex environments where different OEM devices need to be brought into a single monitoring or control system. Whether you’re bridging legacy equipment with modern SCADA or unifying data from multiple vendor PLCs, the CPC Gateway™ provides the necessary flexibility.
How is the CPC Gateway™ different from other protocol converters?
Most converters support only a handful of protocols and one-to-one communication. The CPC Gateway™ supports up to nine protocols simultaneously, across four to six physical ports, and works with over 100 industrial protocols — including Allen Bradley, Modbus, Siemens, BACnet, Honeywell, and more.
How does the CPC Gateway™ simplify integration?
By translating various inputs into a common, pre-configured data map, the CPC Gateway™ eliminates the complexity of mapping and formatting data manually. It enables seamless integration between disparate systems without custom coding or complicated middleware.
How customizable is the CPC Gateway™?
Extremely. Monico engineers can configure the Gateway to pull data from non-standard sources and output it in the exact protocol or data structure required by your control or monitoring system. This customization is what makes it a “custom” protocol converter.
Is this device safe for use in hazardous environments?
Yes. The CPC Gateway™ is C-IL approved for Class I, Div II Groups A-D hazardous locations, making it suitable for use in environments like oil and gas, marine, and heavy industrial settings.
How quickly can I get a CPC Gateway™ up and running?
Thanks to Monico’s pre-configured solutions and intuitive USB interface, installation is quick and setup can often be completed by any technician with basic computer skills. There’s no need to manually map registers — the data is already formatted for integration.
