Ignition SCADA RV50 with a data and SMS cellular plan (not included in the module). The Mobile Module allows the full "Vision" module to run on devices that do not support the Java Runtime Environment. This is accomplished by the mobile client viewing a remote session on the Ignition Gateway. The mobile module requires a javascript compliant browser that supports the canvas element. Compatible examples include: iPad, iPhone, Android 2.2+, and VNC clients. The mobile module allows operators and managers to respond from anywhere to critical data, such as system status, controls system alerts and provides the ability to make notations. The
