The combination of the User Programming and SYPTLite mean that Commander SK can replace nano and some micro PLCs in many applications. A Commander SK ladder logic program can contain up to 50 ladder logic rungs, up to 7 function blocks and 10 contacts per rung. The ladder logic program will be stored on the LogicStick.
Page 14
See the SYPTLite help file for more information regarding using SYPTLite, creating ladder diagrams and the function blocks available. For the associated User Program parameters, see parameter Pr 11.47, Pr 11.48 and Pr 11.50 in the Commander SK Advanced User Guide.

On the larger Commander SK frame sizes, the ratio between maximum continuous current and maximum overload is less than on the smaller drives.
