• The safety partner is created in slot x (primary slot + 1) when changing
from a 1768 Compact GuardLogix to a GuardLogix 5570 controller.
• When changing to a 1768 Compact GuardLogix controller, the safety
partner is removed because it is internal to the Compact GuardLogix
controller..
Floating-point instructions, such as FAL, FLL, FSC, SIZE, CMP, SWPB, and
CPT are supported in GuardLogix 5570 controllers, but not in GuardLogix
5560 and 1768 Compact GuardLogix controllers. If your safety program
contains these instructions, verification errors will occur when changing
from a GuardLogix 5570 controller to a GuardLogix 5560 or
1768 Compact GuardLogix controller.
