Without mapping, data written into these addresses will have no effect on program execution. On the other hand, Logo memory areas VM 0-849 are mutable from outside the controller, but they need to be mapped into the Logo program. Note: These memory areas seem to be read-only from outside the controller, as they are directly used by the function blocks listed in "Logo Block" of the table Logo BlockĭB1,BYTE1024 or DB1,X1024.5 or DB1,WORD1024 The following table shows memory areas accessible without additional settings in the controller program: On the newest Logo! 8.FS4 (and possibly 0BA8) Logic modules there is no need to set the Mode to TSAP any more, instead the default Rack/Slot value of 0/2 works just fine.
