Connect Multiple PLCs from Different Manufacturers to One Gateway
Stop managing separate protocols for Mitsubishi, Omron, Panasonic, KEYENCE, and JTEKT PLCs. M2M Gateways collect data from up to 128 PLCs through a single controller with built-in multi-vendor PLC Master function. Transmit standardized data to cloud services, local HMI, or SCADA systems—without custom programming for each PLC brand.
Why Multi-Vendor PLC Integration Creates Data Collection Bottlenecks
Your factory has Mitsubishi PLCs on Line A, Omron on Line B, and Panasonic on Line C. Each brand uses different protocols, different software tools, and different connection methods. Collecting data from all three? That's where integration becomes expensive and complex.
"Every Manufacturer Uses Different Protocols"
Mitsubishi uses MC Protocol, Omron uses FINS, Panasonic uses MEWTOCOL. Your team needs specialized expertise for each brand. Training takes months. Documentation is scattered across different vendor websites in different languages.
"Need Gateway Hardware for Every Brand"
Traditional approach: Buy Mitsubishi's gateway for Mitsubishi PLCs, Omron's gateway for Omron PLCs, Panasonic's gateway for Panasonic PLCs. Each gateway costs separately. Each has different configuration software. Cable management becomes a nightmare.
"Data Comes in Different Formats"
Mitsubishi PLCs output data in format X, Omron in format Y, Panasonic in format Z. Your cloud service or SCADA system expects one standardized format. You need custom middleware to convert everything—more development time, more points of failure.
"Adding New PLCs Means Starting Over"
Line expansion requires adding more PLCs. If you chose different brand for cost reasons, your existing gateway setup won't support it. You either buy another brand-specific gateway or redo entire integration architecture. Both options waste time and budget.
"Per-PLC or Per-Tag Licensing Costs"
Some industrial gateway vendors charge per PLC connection or per data tag collected. Start with 5 PLCs, seems affordable. Scale to 50 PLCs across multiple production lines—monthly fees multiply. Annual license renewal adds recurring operational expense.
"Separate Tools for Each PLC Brand"
Mitsubishi PLCs monitored via GX Works, Omron via CX-One, Panasonic via Control FPWIN Pro. Your operators juggle multiple software windows. No single view of entire production line. Troubleshooting across different PLC brands requires switching between tools constantly.
Factories with mixed PLC brands face these integration challenges daily. But what if one gateway could communicate with all major PLC manufacturers—using their native protocols—without separate converters or expensive per-device licenses?

| Form Factor | Single all-in-one device | Controller + I/O modules |
| I/O Expandability | Fixed (cannot add I/O) | Up to 16 modules per controller |
| PLC Master | All models | All models |
| OPC UA Server | Selected (-931) | All models |
| 4G LTE | Model -G5 available | Model -G5 available |
| Installation Time | Faster (plug-and-play) | Slightly longer (module assembly) |
