4.1.8.11 FB22 (SEND-ALL), requested data output for 3964(R) with RK512
This data handling block is used for transmitting telegrams to the interface building blocks BG41,
BG42 and BG43, when using the procedure 3964(R) with the RK512 protocol.
The building block transfers the requested data in a telegram on the interface building blocks. The
area, in which the data to be sent is, is described in the request telegram. A request can be triggered
by the data handling block FETCH.
The data handling block SEND-ALL must be cyclically polled (in OB1).
The data handling block posseses formal operands. Several working parameters are to be set
through these formal operands. They can only be directly parametrized.
The following parameters are to be transmitted with the loading of FB22 :
Des. Format Explanation
ADRE KH Address set with DIL switches
SSNR KF Interface number 1,2 (3)
PAFE MB Error messages in relation to parametrizing are filed in this
byte.
NEUS M New start bit
Tab. 4-21:List of parameters for the loading of FB22
The following details are necessary for the abovementioned parameters:
ADRE
Input of the physical start address, under which the building block can be
accessed by the PLC. This start address can be set with the DIL switches S1 and
S2 (see chapter 5).
SSNR
The interface number 1 or 2 is to be given. By the firmware 4017 the number 3
can also be given.
PAFE
Contains a byte for issuing an error number. PAFE provides the value 0, the
parameter details are therefore correct. A value unequal to 0 represents an error.
PAFE Error codes
0 No error
11 Invalid address ADRE
12 Invalid interface number SSNR
16 Undefined answer received by interface building block
NEUS
As long as the bit is at the signal stand is at 1, the processing of the function
block is discontinued.
