Significance
65 The parameter "receiving CPU" (SEND, SEND TEST)
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.
66 The parameter "transmitting CPU" (RECEIVE, RECEIVE
TEST) 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
(SEND, RECEIVE, SEND TEST, RECEIVE TEST). 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 these functions INITIALIZE, SEND,
SEND TEST, RECEIVE or RECEIVE TEST has
already been called in this CPU in a lower
processing level (i.e. cyclic program execution).
- 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.
