Errors
When calling the RECEIVE TEST function, the following error
numbers (evaluation of the condition code byte) can occur:
Condition
code byte
Significance
66 The parameter "transmitting CPU" is illegal.
The following errors are possible:
- The number of the transmitting CPU is greater
than 4,
- The number of the transmitting CPU is less than 1,
- The number of the transmitting CPU is the same as
the CPU’s own number.
67 The special function organization block call is wrong.
The following errors are possible:
- Secondary error, since the INITIALIZE function
could not be called or was terminated by an
initialization conflict.
- Double call: the call for this function, SEND, SEND
TEST, RECEIVE or RECEIVE TEST is illegal,
since one of the functions INITIALIZE, SEND,
SEND TEST, RECEIVE or RECEIVE TEST has
already been called in this CPU in a lower processing
level (e.g. cyclic program processing).
- The CPU’s own number is incorrect (system data
corrupted);
following power down/power up the CPU number
is generated again by the system program.
68 The management data (queue management) of the
selected links are incorrect; set up the buffer in
the coordinator 923C again using the INITIALIZE
function.
Warning
The "warning" number group cannot occur with the RECEIVE TEST
function.
Receiving capacity
The "receiving capacity" parameter indicates how many data fields can be
received and buffered.
