Handling with VIPA data handling blocks Manual BG41/BG42/BG43
4-26 Rev. 99/49
4.1.7.4 FB30 (SYNCHRON) up to firmware 4.1 for 3964(R)
This data handling block prepares the interface building block for operation of the procedure
3964(R).
The data handling block must be loaded in all start branches (OB20,21,22) for each interface to be
used. If two channels are used with the procedure 3964(R), this data handling block must be loaded
twice.
The data handling block possesses formal operands.
Several working parameters are to be set through these formal operands. They are only directly
addressable.
The following parameters are to be transmitted when loading FB30:
Des. Format Explanation
ADRE KH Building block’s address set by DIL switches
SSNR KF Interface number 1,2,3
BAUD KF Baud rate code 1...11 (10 = 9600baud)
FORM KM Transmission format:8bit,even parity,2 stop
PRIO KF 0=low, 1=high priority
BLOC KF Block size in bytes (always even-numbered!)
PAFE MB Byte for the output of a wrong number
Tab. 4-11:List of parameters for the loading of FB30
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, 2 or 3 is to be given.
BAUD
Different baud rates can be set by inputting the respective codes. With the plug
connector J11 on the building block, optional baud rates from 150 to 38400 baud
can be set. In order to achieve this, J11 which has a baud rate of 75 to 19200 baud
in its delivery state, must be replugged.
