        <deif:teaser><![CDATA[<p>User-friendly, free PC software utility for DEIF controllers. PICUS lets you configure, commission, and supervise controllers and includes several advanced features for customizing your application or controller setup. Now, with the integration of iE 250 and iE 350 products, PICUS offers an extended range of capabilities, ensuring seamless compatibility and enhanced functionality for a broader spectrum of applications.</p>]]></deif:teaser>
        <deif:description><![CDATA[<p>PICUS is a free DEIF utility software designed for configuring, commissioning, and supervising controllers and includes advanced features for customizing your application or controller setup. It allows you to carry out complex plant designs from a user-friendly PC interface, for example applications with multiple ring connections.</p>
<p><strong>Fully featured and easy to use</strong></p>
<p>PICUS comes with all the features you need, for example, creation and maintenance of application single-line diagrams, supervision (read-out) of data and information, alarm handling, and system emulation. It can also be used to apply firmware updates for controllers.</p>
<p>Getting started with PICUS is easy: <a href="/software/?product=17615" title="Software" data-anchor="?product=17615">Download the utility from deif.com by clicking this link</a>, install it on your PC, connect to your controller using an Ethernet cable, and launch PICUS. The software offers easy and effective group-based user management.</p>
<p><strong>Customised logic and Flexible Modbus</strong></p>
<p>In addition to standard control features, PICUS offers several advanced but user-friendly features that allow extensive customisation of your application or controller set-up:</p>
<ul>
<li>With the CustomLogic tool, you can create logic functions using drag and drop editing. Based on the well-known ladder logic approach, CustomLogic allows you to customise your controller to your specific requirements without programming experience, and you can develop custom logic that allows you to avoid equipment purchases. For more information, <a href="/blog/customisation/customlogic-makes-controller-customisation-easy/" title="CustomLogic makes controller customisation easy">see this blog post.</a></li>
<li>If you need to add new controllers, including iE 250 and iE 350, to an existing Modbus-based control system, you can use the built-in Flexible Modbus functionality in PICUS to customise the Modbus addresses used in your new controllers so they match your master controller configuration, saving you the trouble of reprogramming your master controller and greatly speeding up system upgrades. For more information on Flexible Modbus, <a href="/blog/customisation/speed-up-system-upgrades-with-flexible-modbus/" title="Speed up system upgrades with Flexible Modbus">see this blog post.</a></li>
<li>Exclusive for iE 250 and iE 350: Introducing the Dashboard Designer feature, a powerful tool that enables you to personalize your user experience and extend the flexibility to accommodate different project needs. With the Dashboard Designer, you can tailor the interface to display key parameters and information specific to iE 250 and iE 350 controllers, providing a unique and efficient monitoring experience. This feature enhances the overall usability of PICUS for these controllers, offering a more tailored and streamlined experience for your projects.</li>

                    <content:encoded><![CDATA[<h3>New features</h3>
<ul>
<li>Improved user confidence and reduced commissioning errors by ensuring that graphs immediately reflect parameter changes, enabling visual validation before committing the configuration to the controller.</li>
<li>Enhanced operational flexibility and system clarity by allowing users to define which controllers are actively controlled and which are feedback-only, supporting safer and more transparent system setups.</li>
<li>Increased data readability and analysis accuracy by optimising grid scaling on ROCOF graphs, enabling better interpretation of system behaviour.</li>
</ul>
<h3>Corrections</h3>
<ul>
<li>Restored expected workflow behaviour by fixing an issue where “continue without saving” had no effect.</li>
<li>Improved configuration usability by re-enabling feedback buttons in the application configuration.</li>
<li>Enhanced workflow stability by preventing automatic switching to “view all” when saving parameter changes.</li>
<li>Ensured accurate system status visibility by fixing delayed controller-ready updates during application creation.</li>
<li>Improved navigation consistency by preventing unexpected jumps to the top menu during adjustments.</li>
<li>Strengthened configuration reliability by resolving an issue related to the Plant ID.</li>
<li>Improved consistency of configuration workflows by fixing a copy-paste-related feedback configuration error.&nbsp;</li>
<li>Ensured accurate system representation by correcting the display of active local sources.</li>
<li>Increased functional flexibility by enabling proper differentiation between GOV and AVR outputs (PWM/AO).</li>
<li>Restored expected configuration behaviour by enabling component label renaming.</li>
<li>Improved parameter accuracy by correcting misleading boolean parameter information.</li>
<li>Strengthened system monitoring by restoring visibility of application supervision alarms.</li>
<li>Improved application stability by resolving start-up issues on new PCs and laptops.</li>
