• A thin underline “_“ indicates a command. A thick underline “_“ indicates data to be read
out.
• Response data do not actually have spaces in between. Spaces are inserted in the
example above to make numbers easy to read.
• For analysis of response data, refer to Appendix, “ASCII Code Table.”
1. Error Status 1
No response is returned when an error is detected in the data link. The detected error is
indicated on Error Status 1. If there is a station that does not return a response within the
expected time, read out the error status immediately to receive the error contents in order to
find out the details of the error.
The contents of the error are saved in Error Status 1, which is updated as an error is
detected in the data link. By setting to 1 the remote reset status or the reset switch of the
UPM100’s main body, Error Status 1 is initialized (in other words, set to &H00, which means
there are no errors).
