Collaboration diagram for Server version since 1.26.0.0 (MLC-FW: 14V22):

Note: Since firmware version 14V22 (MLPI-Server-Version: 1.26.0.0) a centralized permission management has been implemented in target controls XM2, L75 and VPx. Some permissions have been summarized in order to improve their usability. Additional information regarding the usage of older manifest files (i.e. accounts.xml) with newer server versions can be found in Manifest since server version 1.26.0.0.; Users of other CML controls (i.e. L25, L45, L65) have to use the old permissions as defined in Server versions before 1.26.0.0

List of valid permissions for mlpiLogicLib. These permissions shall be assigned to the groups (i.e. in the group manifest file groups.xml) rather than the users.

Permission-Ident	Description
LOGIC_CONFIG	Load PLC application - Allows to load PLC applications.
LOGIC_CONTROL	Start, stop, reset and debug PLC application - Allows to start, stop, reset and debug PLC application.
LOGIC_INFO	View PLC application status - Allows to view PLC application status.
LOGIC_READ	Read variables and memory areas an get address of symbols - Allows read variables and memory areas an get address of symbols.
LOGIC_WRITE	Write variables and memory areas - Allows to write variables and memory areas.
