Parameter Declaration Data type Memory block Description
STATUS OUTPUT WORD I, Q, M, D, L Status parameter STATUS, returns detailed infor-
mation about the type of error.
ADDR_1 IN_OUT ANY e.g. I, Q, M, D Pointer indicating the buffers in the partner CPU
that must be read
ADDR_2 IN_OUT ANY e.g. I, Q, M, D Pointer indicating the buffers in the partner CPU
that must be read
ADDR_3 IN_OUT ANY e.g. I, Q, M, D Pointer indicating the buffers in the partner CPU
that must be read
ADDR_4 IN_OUT ANY e.g. I, Q, M, D Pointer indicating the buffers in the partner CPU
that must be read
RD_i,1≤ I ≤4 IN_OUT ANY I, Q, M, D, T, C Pointers to the area of the local CPU in which the
read data are entered. Only data type BOOL is
valid (bit field not permitted), BYTE, CHAR,
WORD, INT, DWORD, DINT, REAL, DATE, TOD,
TIME, S5TIME, DATE_AND_TIME, COUNTER,
TIMER.
n The remote CPU returns the data and the answer is checked for access problems
during the read process for the data. The data type is checked in addition.
n When a data transfer error is detected the received data are copied into the config-
ured receive data buffer (RD_i) with the next call to FB/SFB 14 and parameter NDR is
set to 1.
n It is only possible to activate a new read process when the previous read process has
been completed. You must ensure that the defined parameters on the ADDR_i and
RD_i areas and the number that fit in quantity, length and data type of data to each
other.
ERROR STATUS
(decimal)
Description
0 11 Warning: the new task is not active since the previous task
has not completed.
0 25 The communication process was initiated.
The task is being processed.
1 1 Communication failures, e.g.
n Connection parameters not loaded
(local or remote)
n Connection interrupted
(e.g.: cable, CPU turned off, CP in STOP)
1 2 Negative acknowledgment from partner device.
The function cannot be executed.
1 4 Error in receive data buffer pointer RD_i with respect to the
length or the data type.
1 8 Partner CPU access error
1 10 Access to local application memory not possible
(e.g. access to deleted DB).
