This allows OPC UA servers and SCADA systems to be separated in different machines, providing greater reliability and security to the infrastructure.<span class=\"Apple-converted-space\">\u00a0<\/span><\/span><\/p>\n<h4 class=\"p4\"><span class=\"ez-toc-section\" id=\"Increased_performance\"><\/span><span class=\"s1\">Increased performance<\/span><span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p class=\"p1\"><span class=\"s1\">OPC UA with SCADA integration also brings greater interoperability. OPC UA has become the communications standard for Industry 4.0, so all control systems and software applications tend to incorporate it into their stack. This means higher performance in all systems, especially in SCADA, where much more data can now be integrated and more valuable information can be obtained for decision making.<\/span><\/p>\n<h4 class=\"p4\"><span class=\"ez-toc-section\" id=\"Increased_efficiency\"><\/span><span class=\"s1\">Increased efficiency<\/span><span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p class=\"p1\"><span class=\"s1\">Being an increasingly integrated standard and accepted by all manufacturers, system integration is practically straightforward. Beyond the security provided by this protocol, today it is much faster and more efficient to integrate systems with each other through OPC UA than through classic OPC or other protocols. Therefore, OPC UA directly implies a saving of time and costs in integration.<\/span><\/p>\n<h4 class=\"p4\"><span class=\"ez-toc-section\" id=\"Greater_flexibility\"><\/span><span class=\"s1\">Greater flexibility<\/span><span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p class=\"p1\"><span class=\"s1\">Trends towards standardization of industrial communications through OPC UA also implies flexibility. Many machinery manufacturers, instrumentation, PLCs and other devices are integrating OPC UA as a standard communications protocol. This means that they can be integrated &#8220;plug and play&#8221; with SCADA systems, especially with those whose native protocol is OPC UA, as is the case with atvise\u00ae software.<\/span><\/p>\n<h4 class=\"p4\"><span class=\"ez-toc-section\" id=\"Greater_interoperability\"><\/span><span class=\"s1\">Greater interoperability<\/span><span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p class=\"p1\"><span class=\"s1\">And in addition to industrial field devices, control systems and PLCs, also higher level software applications are incorporating OPC UA as a communications protocol: MES\/MOM systems, ERP platforms, CMMS systems, alarm management and notification software, and more. OPC UA stands for full interoperability in industrial communications.<\/span><\/p>\n<h4 class=\"p4\"><span class=\"ez-toc-section\" id=\"Greater_scalability\"><\/span><span class=\"s1\">Greater scalability<\/span><span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p class=\"p1\"><span class=\"s1\">All of the above also implies greater scalability. As communications over any network are feasible and secure, and as they are increasingly available on more systems and devices, OPC UA communications infrastructures can be scaled as production grows without any limitation.<\/span><\/p>\n[\/vc_column_text][\/vc_column][\/vc_row][vc_row type=&#8221;in_container&#8221;

Summarizing it a lot and leaving information pending to be extended, it could be said that OPC UA is oriented to &#8220;heavy&#8221; industrial communications (data with alarms, metadata, historization, formats, structures, instances and others) while MQTT is oriented to light communications, justifying itself very well when networks between the systems to be connected are very weak, very remote or when there is charge for traffic. In any case, there are platforms such as vNode Automation that facilitate hybrid OPC UA and MQTT systems.[\/vc_column_text][\/vc_column][\/vc_row][vc_row type=&#8221;in_container&#8221; full_screen_row_position=&#8221;middle&#8221; column_margin=&#8221;default&#8221; column_direction=&#8221;default&#8221; column_direction_tablet=&#8221;default&#8221; column_direction_phone=&#8221;default&#8221; scene_position=&#8221;center&#8221; text_color=&#8221;dark&#8221; text_align=&#8221;left&#8221; row_border_radius=&#8221;none&#8221; row_border_radius_applies=&#8221;bg&#8221; overlay_strength=&#8221;0.3&#8243; gradient_direction=&#8221;left_to_right&#8221; shape_divider_position=&#8221;bottom&#8221; bg_image_animation=&#8221;none&#8221;][vc_column column_padding=&#8221;no-extra-padding&#8221; column_padding_tablet=&#8221;inherit&#8221; column_padding_phone=&#8221;inherit&#8221; column_padding_position=&#8221;all&#8221; background_color_opacity=&#8221;1&#8243; background_hover_color_opacity=&#8221;1&#8243; column_shadow=&#8221;none&#8221; column_border_radius=&#8221;none&#8221; column_link_target=&#8221;_self&#8221; gradient_direction=&#8221;left_to_right&#8221; overlay_strength=&#8221;0.3&#8243; width=&#8221;1\/1&#8243; tablet_width_inherit=&#8221;default&#8221; tablet_text_alignment=&#8221;default&#8221; phone_text_alignment=&#8221;default&#8221; column_border_width=&#8221;none&#8221; column_border_style=&#8221;solid&#8221; bg_image_animation=&#8221;none&#8221;][vc_column_text]\n<h3><span class=\"ez-toc-section\" id=\"How_and_when_should_we_change_the_M2M_communication_protocol\"><\/span>How and when should we change the M2M communication protocol?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>To make any software change, you must be very clear about the target you intend to achieve.
