Murrelektronik's Modlink MSDD programming ports provide convenient and safe access to the controls when diagnostic or service work is necessary, without having to open the cabinet doors. A variety of country-specific sockets and data connectors provide high flexibility, and comprehensive approvals provide for worldwide applications. Modlink MSDD programming ports can be specified on new control panels or retrofitted to existing panels.
Software for control units often has to be updated during operation, which requires laptops or diagnostic devices to be connected. This is often only possible with the cabinet door open, which costs time and money, particularly if operation has to be suspended while the door is open. If diagnostic data has to be read or software changes made during operation, service technicians sometimes come up with a makeshift means of accessing the control unit. Such temporary wiring can be prone to errors and is less than ideal.
However, this problem can be avoided by using the Modlink MSDD front panel interface. The modular Modlink MSDD consists of standardised single or double frame made of metal or plastic that is installed into the control cabinet. More than 170 different inserts with country-specific sockets and data interfaces (for example, SUB-D, RJ45 or USB) can be snapped into place. Whether the machine is destined for use in China, Canada, France or in almost any other country, Murrelektronik can provide the necessary inserts.
For industrial applications, standards require sockets to be protected up to 20A using residual current devices (RCDs). A commercially available two-pole safety switch can therefore be integrated within the Modlink MSDD. After an error, the safety switch can be reset.
For data communication, the insert can be equipped with a USB-A or RJ45 connection, depending on the application requirements. The result is a complete programming interface including a secured electrical connection. According to Murrelektronik, this is unique on the market.
Modlink MSDD front panel interfaces feature sealed covers with double-bit locks as are commonly used on control cabinets, and the interfaces are certified by UL according to cURus. The approval for the inserts is a design approval, so newly configured inserts are as of now approved according to cURus.
