Area of application for PiEl64/256
The block is used for the following applications:
● Reading a parameter of the basic data type by means of acyclic data in combination with
driver block PiDr64/256
How it works
The block initiates reading of the data record via driver block PiDr64/256 on request. A
parameter of the elementary data type that is addressed via the block inputs is read from the
data record and made available at the block output.
Note
The PiDr64/256block is capable of simultaneous processing of several read jobs in successive
order only. If read jobs are started by several blocks, the blocks are executed based on the call
sequence. It is advisable to configure the program so that simultaneous initiation of multiple
jobs is safely prevented.
