Response Monitor Area (Offset: +0)
This area contains the results of communications when communicating with
the component to write variables.
1. End Code = 00
When the function's end code is 00, the "response monitor area" contains
the response code.

2. End Code ≠ 00
When an error occurs and the function's end code is a value other than 00,
the "response monitor area" contains the end code (error code). The value
of FF in the first two digits indicates that an error occurred during transmis-
sion of the CompoWay/F command.

Note A Not Defined Error can occur when using SYSWAY communica-
tions with a general-purpose communications component. An exam-
ple of a Not Defined Error would be when a Temperature Controller
was connected via SYSWAY and the Temperature Controller was set
for ON/OFF control, yet a command was sent to read the proportion-
al band, integral time, and derivative time. A Not Defined Error would
occur in this case.
