With redesigned POWERLINK rotary encoders based on an FPGA design, POSITAL offers users a cost-efficient way to perform migration from CANopen to the Ethernet-based successor standard. The mounting depth of the new generation of encoders has been greatly reduced. All outer dimensions are now identical to those of the field bus models. They allow cycle times as short as 250 Î¼s.
In addition to the classic polling mode, during which the master or managing node polls each Slave or controlled node, the "Poll Response Chaining" and "Multiplexing" modes are also supported. This extension of operation modes makes it more efficient for customers to implement their own time-critical applications and raise system bandwidth using the new interface design.
Rugged M12 connectors certified to protection class IP67 bring another advantage for connectivity. Pre-assembled custom cables reduce installation work while helping to avoid installation errors. The connection hood is equipped with two rotary switches. While it was detachable in previous versions, it is integrated in the new encoders.
Two hex-coded address switches accessible from the outside are also rated IP67 and allow setting of the host ID within the net ID in an easy way. This reduces the effort required by network administrators for maintenance and integration. With an integrated hub and thanks to very short propagation delays, lengthy line structures can be implemented as well. Diagnostic LEDs show traffic intensity and link conditions at each port connection as well as the condition of the device from the network's point of view.
