FILE Command
The FIL command (see Table 7.17 ) is intended to be a safe and efficient

external support software (ESS). The FIL command ignores the hide rules and
transfers visible as well as hidden settings, except the settings hidden by a part
number.

Use the GOOSE command to display transmit and receive GOOSE
messaging information, which can be used for troubleshooting. The GOOSE
command variants and options are shown in Table 7.18.
