Frequently Ask Questions
Q: How do you prevent Modbus RTU timeout errors when polling over a high-latency cellular network?
A: This is a common pitfall. Traditional Modbus RTU is highly sensitive to timing delays, and polling a remote serial device directly from a cloud SCADA over a 4G network often results in communication timeouts. Our gateways solve this by acting as an “Edge Modbus Master.” They poll your RS485 devices locally at high speed (where latency is zero), package the data, and transmit it to the cloud via MQTT or HTTP. This completely eliminates latency-induced timeout errors.
Q: Can I connect multiple legacy RS485 devices (like VFDs and meters) to a single cellular gateway?
A: Yes. You don’t need a separate modem for each machine. Our gateway allows multiple Modbus RTU slave devices to be daisy chained on a single RS485 bus. You can configure the device to poll the specific registers of each slave ID on the network and aggregate all the metrics into one single very efficient data stream which is sent to your centralized dashboard.
Q: Can I use this gateway to remotely program my older serial PLCs?
A: Absolutely. The cellular gateway creates a transparent pass-through connection through Virtual Serial Port (VCOM) software on your local PC. This allows your legacy programming software (such as RSLogix for older controllers) to communicate with the remote PLC over the cellular network exactly as if you were plugged directly into its serial port on-site, saving countless travel hours.
Q: Is it secure to transmit unencrypted legacy serial data over public 4G networks?
A: Native Modbus RTU and RS232 have zero built-in security. To protect your OT (Operational Technology) data, our gateways never send raw serial packets over the open web. They locally convert the serial data and they use SSL/TLS encryption on all MQTT payloads keeping your legacy equipment completely safe from public internet scanning. For applications requiring complete network-level isolation, you can also explore our Industrial Cellular VPN Routers for hardware-level IPsec and OpenVPN tunnels.
