9.7.8.1 Definition in the SM_EtherCAT.lib library
9.7.8.2 The data type ECAT_STATE
The data type ECAT_STATE describes all possible states of the EtherCAT bus system:
9.7.8.3 Variables
The variables of the EtherCAT master structure ECAT_MASTER provide additional
information besides the state of the EtherCAT bus system:

Note!
Only one EtherCAT master instance can be executed on an IPC. (The global
variable g_ecatMaster[1] contains the master state for the ECAT1 interface.)
