FAQs
Frequently Asked Questions
What does the J1939 Gateway™ do?
The J1939 Gateway™ is a pre-configured device that reads SAE J1939 data over a CAN bus network and translates it into one of 80+ industrial protocols. It’s designed to make it easy to integrate J1939 engine data into SCADA, PLC, or remote monitoring systems.
What types of equipment use J1939?
J1939 is commonly used in mobile and industrial diesel engines — including equipment from Cummins, John Deere, Perkins, Deutz, Detroit Diesel, and others. It’s also the standard protocol for non-Caterpillar® gensets and many off-highway or transport assets.
How is Monico’s J1939 Gateway™ different from others on the market?
Unlike most converters, the J1939 Gateway™ balances pre-configured simplicity with deep protocol flexibility. It supports both standard and proprietary PGNs and translates them into major protocols like Modbus, BACnet, SNMP, and Allen Bradley — with minimal setup required.
Can I convert proprietary PGNs, or just standard ones?
Yes, you can do both. The Gateway supports conversion of any standard or proprietary PGN, allowing it to work with custom engine implementations or manufacturer-specific extensions.
What data can I monitor using this gateway?
You can access key engine parameters such as RPM, coolant temp, fuel rate, engine hours, fault codes, and more — depending on what your engine supports over J1939. The Gateway includes hundreds of pre-mapped registers out of the box.
How many communication protocols are supported?
Over 80 output protocols are supported, including industry standards like Modbus RTU/TCP, BACnet/IP, Ethernet/IP, Allen Bradley (SLC and ControlLogix), GE Fanuc, Siemens, and SNMP. The Gateway can communicate on up to four ports simultaneously (serial and Ethernet).
Is it compatible with Caterpillar® engines?
Yes — specifically EMCP 3 and 4 series gensets, which use J1939 instead of Cat Data Link (CDL). For other CAT equipment using CDL, Monico’s CDL Gateway™ would be the better fit.
Is the Gateway easy to install and configure?
Yes. The J1939 Gateway™ is C-UL listed for Class I, Div II Groups A-D, meaning it’s safe for use in hazardous or industrial areas like oil & gas or marine applications.
Can I add more than engine data to my system?
Yes. Optional I/O modules allow you to integrate additional signals like fuel level, bearing temperature, analog inputs, and digital controls — giving you a more complete monitoring system around the engine.
How fast does the Gateway collect data?
It polls data at speeds of 20–60 parameters per second, depending on network traffic and engine configuration — enabling real-time visibility into engine performance.
