_EC_SlavErrTbl Slave Error Table This system-defined variable gives the error
status for each EtherCAT slave. The error sta-
tus is given for each slave in the actual system
configuration. This variable array indicates
slaves in which there are errors. Status is pro-
vided for each EtherCAT slave node address
(1 to 192). Refer to information on the mean-
ings of the error status bits at the end of this
appendix for details.
