SEW-Eurodrive has revamped its modular encoder system consisting of built-in and mount-on encoders. The IP66-protected EI8C and EI8R encoders are designed to be built into, or retrofitted to, motors and come in sizes 71–180. They have HTL and TTL interfaces and 1,024-increment resolutions. The updated EK8C, EK8R, EK8S, AK8W and AK8H sin/cos encoders mount on a motor behind the fan and offer HTL and TTL, and SSI or Hiperface interfaces. Brake wear can be measured without having to disassemble the encoder. Weidmüller is offering a load-monitoring systemwhich uses IO-Link to provide communications between machines, control cabinets, IT systems and the cloud, thus offering new control, monitoring and analysis options. The topGuard system can also be used to protect 24V systems and has built-in potential distribution which saves space and installation time. COMMUNICATIONS, IoT AND THE CLOUD Controllers from Mitsubishi Electric ’s Melsec FX5, L, QnA and iQ series can now be connected to higher-level systems via an enhanced version of the DIN-rail-mounting IBH Link UA module which acts as an OPC UA server/client modules with a firewall. The module has four Ethernet ports and a 24V power supply and can exchange user- defined OPC UA variables with an MQTT broker, thus linking it to the cloud. It will soon be possible to connect Mitsubishi robots with OPC UA CS as well. Murrelektronik was demonstrating a Profinet/ProfiSafe module that combines digital sensors and actuators, safety digital sensors and actuators, and a pair of IO-Link ports. Configuration can be done using engineering tools in safety control systems, and installation is said to be fast and easy, with fewer fieldbus modules needed. Safety sensor signals are transmitted via three two-channel safe input ports, while the safety output port has two configurable safe outputs. Following its recent acquisition of US-based Comtrol, Pepperl+Fuchs has enhanced its IO- Link range to help users improve dataflows from field devices to controls and the cloud. P+F is also using the acquisition to reinforce its Sensorik 4.0 offerings – in particular, managed and unmanaged switches, and interface converters for connecting existing installations to IoT devices such as IO-Link masters. One example of the enhanced range is a 30mm-wide, multiprotocol IO-Link master with an M12 power connector and a built-in Web server. There is also one IO-Link hub with ten digital inputs, six digital outputs, and another with 16 freely-configurable digital I/O. Finally, there is an IO-Link signal tower that can combine up to five signalling elements. Phoenix Contact has extended its FL Network Manager software to include topology representation (enabling device connections for each network port to be visualised and checked) and SNMP scripting (enabling deeper diagnostics to be performed on network structures). Version 3.0 of the software can check whether the actual network structure corresponds to the planned structure, and can show at a glance the roles of individual ports and devices in a redundancy system. Siemens launched a new version (2.0) of its Sinetplan tool for planning and simulating Profinet networks, which allows configuration data for a planned plant to be imported from ECAD (electronic computer-aided design) systems or its TIA selection tool using the AutomationML data exchange format. Siemens says that the tool provides a transparent, virtual representation of planned networks and offers opportunities for optimising them. Softing was demonstrating a gateway that connects Profibus PA and DP devices with Profinet controls. The pnGate PB allows Modular access control system can be retrofitted Pilz was demonstrating a flexible, modular access permission management systemwhich can be integrated into existing control consoles and can use existing pushbuttons. The PITmode fusion system consists of a reader with integrated RFID technology and aWeb server (the PITreader) and a safe evaluation module (SEU). It is aimed at machines which need to switch between different control sequences and operating modes. Authorised users can perform their tasks using coded RFID transponder keys. There are up to five safe operating modes, including automatic modes, manual intervention under restricted conditions, and service modes. When a key is inserted, the SEU detects the mode, and the PITreader ensures safe switching, thus preventing accidents, misuse and manipulation. The RFID keys are read and taught in the PITreader, which can be company- specific. Group-based permission management is possible. The PITmode fusion system can also be used for other tasks. For example, a simple enable can replace a keywswitch or give permission to access machine sub-functions. Complex, hierarchical permission matrices can be created.
