Bits
Note Command Code 30–Control Remote Bits
This code controls the remote bits. This command code has two parameters:
Parameter 1 determines the bit operation.
Parameter 2 determines which bit to control. It is bitmasked for future expansion, but only one bit can
be controlled at a time. The highest numbered bit will be controlled if more than one bit occurs in the
parameter.

Error Codes

In addition to the error codes returned for function codes 06h or 10h, the following error codes
are returned for command codes.
•
If the relay is disabled or if the breaker jumper is not installed while the commands 1–4 and
7–26 are issued, the relay will return error code 04 (device error).
•
If the relay is disabled while Reset Targets command (05) is issued, the relay will return
error code 04h (device error).
