Product Exclusive: Secure industrial cellular modem

OnCell G3100 industrial RS-232 or RS-232/422/485 GSM/GPRS/EDEG IP modems from Moxa Technologies Inc. are designed to transmit data and short messages (SMS) over GSM/GPRS/EDEG cellular networks, allowing communication with remote serial devices.


Moxa is introducing the OnCell G3100 series industrial modems, capable of transmitting messages over cellular networks.

OnCell G3100 industrial RS-232 or RS-232/422/485 GSM/GPRS/EDEG IP modems from Moxa Technologies Inc. are designed to transmit data and short messages (SMS) over GSM/GPRS/EDEG cellular networks. The Real COM operation mode automatically generates a virtual COM port to match serial ports supported by the OnCell G3100, allowing communication with remote serial devices. The unit’s CPU comes pre-installed with the TCP/IP protocol suite to transmit data between the serial device and cellular TCP/IP network and back.

It also comes with a built-in relay output that can be configured to indicate the priority of events when notifying or warning engineers in the field, and two digital inputs allow connection to basic I/O devices, such as sensors, to the cellular network. It can be mounted on a DIN-rail, and the 12 to 48 V dc power input has 2 kV EFT/surge protection to allow the use of different field power sources; 15 kV ESD line protection for serial ports keeps the system safe from unexpected electrical discharges.

It also supports universal quad-band 850/900/1800/1900 MHz GSM/GPRS and choice of operation modes, including TCP Server, TCP Client, UDP, Real COM driver, and RFC2217. The industrial modem also has secure modes for TCP Server, TCP Client, and Real COM; versatile GSM/GPRS connection modes; redundant DC power input; and LED indicators for status and signal level. Configuration methods include Web console, serial console, and Telnet.

Annual Salary Survey

After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.

The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
