System Upgrade Procedure
3.1
Upgrading FA-M3
■
Evolution of FA-M3
●
The evolution of FA-M3 since its debut in 1992 has always considered
upward compatibility so an existing FA-M3 system can be easily
migrated to the latest FA-M3V.
■
Upgrade procedure
●
STEP 1: Select replacement module
Select a replacement module by referring to replacement product
table.
●
STEP 2: Convert ladder programs
Ladder programs are upward compatible so existing programs
developed using earlier programming tools can be converted for new
programming environment.
●
STEP 3: Other changes
・Adjust for higher processing speed
The faster processor in the latest sequence CPU module allows a much shorter
scan time. Timing adjustment might be necessary for scan-time dependent
processing.
・Modify ladder program after upgrading special module
Some special module models are software incompatible with replacement
products. Replacement guides are available for these.
