Explanation
0421H DByyH Data block not loaded
yy = number of the data block that is not
loaded
0422H FByyH Function block not loaded
yy = number of the function block that is not
loaded
0423H FByyH Function block not recognized
yy = number of the unrecognized function
block
0424H FByyH Function block loaded with wrong PG
software
yy =number of the function block
0425H DByyH Wrong controller data block length
yy = number of the data block
0426H — There is not enough memory space in the
DB-RAM to shift the controller DBs from the
user EPROM to the DB-RAM
