ABB (Germany) has added the PM595 to its AC500 series of PLCs. It comes with a range of communication possibilities including CAN and CANopen.
AT THE SPS IPC DRIVES 2014 IN NUREMBERG, ABB is extending the capability of one of its PLC series - the AC500 - with a high performance version called PM595. The unit features a multi-processor system with the performance to handle demanding machinery and motion automation control and communication tasks. According to the company the machinery controller is suitable for robust, high performance industrial control, and is built around a 1,3 GHz processor with four 32-bit RISC processors plus an embedded double-precision floating point processor, 16 MiB of user program memory and a range of communications interfaces.
The computational capability allows the controller to handle control tasks, involving complexities such as precision coordinated motion with several axes, and mathematics-intensive computation such as real-time trigonometric calculations for robotics or other advanced kinematic applications. The controller also has a built-in interface to allow the PLC to be connected for high risk applications.
Versatile connectivity is central to the machinery controller's design. This allows it to be used with both legacy systems and today's favored networks - as well as providing a soft architecture that can handle future demands. Four Ethernet interfaces and an integrated network switch are built in. Two of these interfaces are programmable, supporting Ethercat and Profinet - allowing the PLC to be connected to control two different types of network simultaneously. CAN and CANopen, TCP/IP, UDP, and two EiA-232/485 serial interfaces complete the on-board connectivity. Further networking and fieldbus interfaces may be added via the PLC's dual expansion ports.
This variety of communication possibilities gives users the means to evolve control networks, to add machinery or equipment into control system networks for example, even if located on another process line or location. The PLC is compatible with the range of AC500 expansion modules. Users can also build systems with integrated functional safety, connecting company's PLC directly onto a second expansion port. This provides flexibility for implementing safety-critical applications.
"Machinery and motion control applications are becoming much more complex as machinery becomes more capable, smarter and safer, and as demands for more sophisticated human interfaces and communications grows," said ABB's product marketing manager, Wangelis Porikis. "The sheer computational capability of the AC500 PM595, with its rich feature set and versatile communications capability, provides enormous flexibility for automation builders. It provides a controller that can handle virtually any application, but also one that is highly software-configurable - giving OEMs a single control platform for a very broad range of applications."
The PLC uses non-volatile MRAM memory, and operates without fan cooling. An alternative variant of the AC500 PM595 is additionally available for controlling equipment operating in harsh conditions and extreme climates. The XC or “Extreme Conditions” version of the PLC adds further protection against a variety of threats to reliability including high and low temperatures, high humidity, low air pressure, salt mist and hazardous gases, and vibration and shock. This can reduce industrial control system building costs by eliminating the need for sophisticated protective enclosures with special seals, HVAC, shock absorbers, EMC protection, etc.
The PLC is compatible with ABB's Automation Builder programming capability. This engineering development environment provides an integrated tool-suite for control and motion systems based on PLCs, safety PLCs, motion control, and related automation components - reducing software complexity. All tools required for configuring, programming, debugging, and maintaining automation projects are provided via an interface.
"PM595 offers control engineers a single platform for today's and tomorrow's applications," added Porikis. "The associated Automation Builder engineering tool completes the solution for developers and owners - providing the means to simplify control engineering and standardize on one development platform for all projects - regardless of scale."
The PM595 is capable of controlling over 64 motion axes within a 1-millisecond cycle. The communication and security capabilities of the PM595 also suit “telecontrol” or SCADA supervisory control and data acquisition applications - as required in areas such as power system monitoring and control. The controller is also suitable for applications such as wind turbines or remote SCADA nodes in deserts or Arctic conditions, safety-critical applications in equipment such as cranes, mining hoists or automatic guided vehicles.
