Errors When the SEND function is called, the following error numbers
(evaluation of the condition code byte) can occur:
Condition
code byte
Significance
65 The parameter "receiving CPU" is illegal.
The following errors are possible:
- The number of the receiving CPU is greater than 4,
- The number of the receiving CPU is less than 1,
- The number of the receiving 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.
69 The parameter "block ID" is illegal.
The following errors are possible:
- The block ID is less than 1,
- the block ID is greater than 2.
70 The parameter "block number" is illegal, since it is a data
block with a special significance.
The following errors are possible:
- If the block ID = 1 : DB 0, DB 1
- If the block ID = 2 : DX 0
71 The parameter "block number" is incorrect.
The specified data block does not exist.
72 The parameter "field number" is incorrect. The data
block is too short or the field number too high.
