Since release 1.2 the 4DIAC initiative now also supports the Industrial Ethernet protocol Ethernet POWERLINK – EPL – (www.ethernet-powerlink...). For this purpose the open source implementation openPOWERLINK (openpowerlink.sourcefo...) has been integrated into the 4DIAC environment. Currently, the FORTE runtime serves as master node for accessing distributed I/Os (i.e., client nodes). Therefore, special EPL Services Interface Function Blocks have been implemented for the master and client node functionality.
A first application using this new I/O bus system was implemented by AIT. In order to control a research test bed for testing Smart Grids solutions the 4DIAC/EPL approach is used. Some more details are provided in Industrial Ethernet Book Issue 71 / 43 (www.iebmedia.com/index...).
