9.1 Enhanced PLC Security Mode
 Limitations on functions
Inform end users of the limitations on functions for the E/U project.
For example, add a phrase like this to the manual.
Connecting to a project other than the E/U project is not possible. Formatting from PLC on-board and GX Developer/GX
Works2 is not possible. It is also impossible to modify multi-project parameters from PLC on-board.
 Maximum number of steps for E/U project
Inform end users of the limit for the total number of steps of an E/U program that can be stored in the E/U project.
The maximum number of steps depends on the project ratio of multi-project parameter.
For example, when the NC is M80VW, E/U project No is 3, and the project ratio is like the following figure, the maximum
number of steps is calculated to be "13107" by the formula below.
64K (steps) × 0.20 = 13107.2 (steps)
 Common devices for E/U open interface and the meaning of the signals to be assigned
Inform end users of the input side devices (M, D devices), output side devices (X, Y, R, ZR devices), and the signals assigned
to output side devices of the E/U open interface created by MTB program.
For example, if M1024 to M2047 and D128 to D511 are set as E/U open devices and the E/U open interface is set like the
following figure, provide end users with information in the table below.
