The user program sends this structure to the Web-IO to reset
the counter state of a certain input counter to 0. Which input is
intended is sent in the variable counter_index
ClearCounter
(PC -> Web-IO)
IO-Structure ReadDiagnosis
If the Web-IO determines that there is a communications or
system error, the latter is listed on the HTML page diag and can
be read using the browser. Since error management via browser
for program-controlled applications is not always available, the
error status of the Web-IO can be queried using the structure
ReadDiagnosis
ReadDiagnosis
(PC -> Web-IO)
The Web-IO replies with a Diagnosis type structure.
IO-Structure Diagnosis

gnosis type structure.
Diagnosis
(PC <- Web-IO)
The variable diag_error_count returns how many various errors
are currently in the error memory. The Web-IO distinguishes a
total of up to 64 different error states, whereby each set bit of
the two variables diag_errrorbits0 and diag_errorbits1 stands
for an error type.
