Embodiment Construction

[0024] figure 1 Shown is an EtherCAT fieldbus system 1 with an EtherCAT master 2, a plurality (in the present case exemplarily three) EtherCAT slaves 3 and a diagnostic and / or commissioning device (EtherCAT Configuration Tool (EtherCAT Configuration Tool)) 10, wherein the EtherCAT master 2 and a plurality of EtherCAT slaves 3 are coupled to each other by means of the EtherCAT field bus 4 of the EtherCAT field bus system 1 for data exchange.

[0025] The following steps are involved in starting, starting or starting up the EtherCAT fieldbus system 1 .

[0026] The EtherCAT master 2 determines the active EtherCAT slave 3 and then queries the corresponding product code 6 of the active EtherCAT slave 3, see figure 2 .

[0027] EtherCAT host 2 in case of product code mask 9 (see figure 2 ) to determine the corresponding device identifier 7 of the active EtherCAT slave 3 in sequence according to the corresponding product code 6 (see figure 2 ), and if the corresponding device...

Abstract

A method for operating an EtherCAT fieldbus system (1), wherein the EtherCAT fieldbus system (1) has an EtherCAT master (2) and a plurality of EtherCAT slaves (3), wherein the EtherCAT master (2) and The plurality of EtherCAT slaves (3) are coupled to each other by means of the EtherCAT fieldbus (4) for data exchange, wherein the method has the following steps: - Determining the active EtherCAT slave by means of the EtherCAT master (2) (3); - by means of said master (2) interrogate the corresponding product code (6) of the active EtherCAT slave (3); - by means of said EtherCAT master (2), according to said corresponding product code (6) ) to determine the corresponding device identifier (7) of the active EtherCAT slave (3); and - if the corresponding device identifier (7) of the active EtherCAT slave (3) matches the predetermined If the device identifiers (8) are consistent, the state of the EtherCAT fieldbus system (1) is switched to an operational state by means of the EtherCAT host (2).

Description

technical field [0001] The invention relates to a method for operating an EtherCAT field bus system and an EtherCAT field bus system. Background technique [0002] For EtherCAT (ETC) bus communication, the EtherCAT master requires a predetermined configuration, a so-called ENI file, in which the bus topology with the corresponding slaves and their identification features and ETC properties is mentioned. [0003] Conventionally, the EtherCAT master identifies the EtherCAT slaves on the bus and compares the identified characteristics with the corresponding specifications in the ENI file, so that other characteristics of the identified EtherCAT slaves can be used to compare These identified EtherCAT slaves are parameterized. In this case, the identification characteristics of the EtherCAT slave are: Vendor ID (VendorID), Product Code (ProductCode) and Revision (Revision). If the bus configuration found with respect to the identified EtherCAT slave does not match the bus confi...
