End Codes If an end code of 00 was returned in the response, the command was executed
normally. If the end code is not 00, the desired data will not have been read. Re-
fer to
Section 4-1-2 End Codes for a description of the other possible end codes
and their meanings.
4-2-22 Output Variable Read: RO (RX)
This command is used to read the percentage of output for the specified control
point.
Command Format The format for this command is as shown below. Either a header code of RO with
a data code of 00 or a header code of RX with a data code of 01 can be used. The
unit number and control point must be specified.

Response Format The response returned for this command is shown below. The same header
code as the one used in the command is returned. This response assumes that
the header code in the command block was transmitted and read normally and
that the end code is 00. If the end code is not 00, the output percentage will not
have been read and the end code will be followed immediately by the FCS. If the
header code in the command block was not recognizable, a header code of IC
will be returned without an end code (see
Section 4-1-2 End Codes for the IC
header code response format).
The output value is returned as a four-digit percentage with an accuracy of one-
tenth of a percent.
