The LS_ParReadWrite_1 ... LS_ParReadWrite_6 system blocks are used for reading and writing local

• If several system blocks are activated at the same time, the blocks will be processed one at a
time every time the main program is executed.
• The SB supports one-time and cyclic reading/writing in an adjustable time interval.
