Red Lion Controls has introduced a GSM cellular modem card for its G3 line of human-machine interfaces (HMIs).

The G3GSM allows G3 operator interface products to communicate with operators via cellular technology, providing connectivity for remote and mobile applications.

The expansion card is configured with Red Lion’s free Crimson software and uses a SIM card, allowing customers to choose their own cellular provider.

According to the company, upon establishing a cellular connection to a G3 with G3GSM installed, users can take advantage of the G3 series’ remote capabilities.

These include a built-in web server, which allows viewing of the same screens that are displayed on the G3 or viewing of data-only or logged files, and the ability to upload/download G3 databases without being on site.

The G3 will auto-dial to send out alarm or event information via text message to a mobile phone or an email account or to send scheduled back-up of logged data to an FTP site or an email account.

The G3 series also features a port-sharing feature that enables many PLCs and other attached devices to be remotely reprogrammed through the G3, again eliminating the need to be on site.

Jesse Benefiel, Red Lion’s product manager, said: ‘While wireless connectivity is not new to the G3 series, the wireless connection was previously only possible through external third-party modems.

‘Red Lion’s G3GSM allows for the ultimate functionality in remote system management.’ With the G3GSM and required SIM card, users can choose the cellular provider and plan that best meets their level of desired connectivity – either on demand or permanent.

The on-demand connection is established only when the G3 needs to perform a function of sending or receiving data and is usually less expensive than the permanent connection, which is continually established and requires a fixed URL and/or an IP address.
