Saving and loading circuit diagrams
The logic relay provides you with two ways of saving circuit 
diagrams externally:
• Saving with the memory module 
• Saving to a PC running CL-SOFT. 
Once they have been saved, programs can be reloaded into 
the logic relay, edited and run.
All circuit diagram data is saved in the logic relay. In the 
event of a power failure the data will be retained until the 
next time it is overwritten or deleted.
Memory module
Each CL-LAS.MD003 memory module contains one circuit 
diagram and is inserted in the interface of the logic relay. The 
program is stored retentively on the memory module.
The way the memory module works and a description of how 
to transfer a program to the module is given in on section 
“Memory module”, Page 239.
CL SOFT
CL-SOFT is a PC program with which you can create, store, 
test and manage CL circuit diagrams.

The circuit diagram display performs two functions:
• In STOP mode it is used to edit the circuit diagram.
• In RUN mode it is used to check the circuit diagram 
using the power flow display.

MD001 memory modules of the AC010 devices can be 
read in CL-LSR/CL-LST. Memory modules MD001 and 
MD002 of AC010 devices can be read in the CL-LMR/
CL-LMT.
Only the CL-LAS.MD003 memory module can be write 
accessed by CL-LSR/CL-LST and CL-LMR/CL-LMT.
