FORM
Transmission format: The command is a two-byte-command.
High-Byte 0 = Operation with a procedure 3964
1 = Operation with a procedure 3964(R)
Low-Byte Transmission format of the serial interface.
PRIO
Priority: Controls the telegram procedure by initialization conflict
0 = low priority
1 = high priority
BLOC
The block size indicates how many bytes are to be exchanged between the PLC
and the interface building block every time the data handling blocks SEND and
RECEIVE are loaded. The greater the number of bytes to be exchanged, the
higher the cycle time load.
The block size has no influence on the data transmission! The building block only
begins with the output of telegrams, when all data to be output has been
transferred from the PLC to the building block.
The standard setting is a block size of 128 bytes. Only for "slow" PLCs e.g. CPU
941/942, can it be necessary to set the block size at a smaller value, so that the
cycle time load is not too large.
