 Alternatively,​ you can download the free software [[https://​www.elmomc.com/​product/​easii/​ | EASII]] (Elmo Application Studio 2) from Elmo.  In this case you need a hardware EtherCAT master from Elmo, e.g. the [[https://​www.elmomc.com/​product/​gold-maestro/​ | Gold Maestro]] from Elmo. Alternatively,​ you can download the free software [[https://​www.elmomc.com/​product/​easii/​ | EASII]] (Elmo Application Studio 2) from Elmo.  In this case you need a hardware EtherCAT master from Elmo, e.g. the [[https://​www.elmomc.com/​product/​gold-maestro/​ | Gold Maestro]] from Elmo.
  
 +===== Create ENI file ======
 +The exact procedure depends on the software used. However, the following procedure can always be used:
 +
 +  - Select a slave
 +  - The EASII already has all ESI files for the Elmo Drives. If the required ESI file is not yet available:
 +    - Get the ESI file from the manufacturer
 +    - Import the ESI file 
 +  - Attach a slave to the EC master (If EC-Engineer is used by Acontis, attach the slave to the PC)
 +  - The slave must be supplied with power.
 +  - Scan the network
 +  - The slave should be detected
 +  - Test if you can read an encoder value
 +  - Connect the complete EC network and scan again
 +  - Define the period duration for PDOs (typically 1msec)
 +  - Define all variables which are to be sent or received with the PDOs from the slaves.
 +  - Export the ENI file
 +
 +If one of the following points changes, then the ENI file must be rebuild:
 +  * Topology
 +  * Period duration
 +  * Exchanged variables via PDO
