4-5-4 Exit Setup Mode
To exit from Setup Mode, set the Mode Control Bit (IR m.01) to 0, while the
MOD switch remains OFF. The Master will return to Configuration Mode. It is
not possible to switch from Setup Mode to Protected Mode by setting the
MOD switch from OFF to ON while the Mode Control Bit is ON. This is to
avoid conflicts when the PLC is programmed from a remote location, while the
switches can be operated locally.
If the MOD switch is set from OFF to ON while in Setup Mode, the ERR LED
will light to indicate that the requested mode change could not be made.
The user is to make sure that when the AS-Interface master leaves Setup
Mode, the appropriate output data for slaves 1~7 is available in IR m bits
04~15 and IR m+1 bits 00~15.
The output data for slaves 1~7 should be set to IR m and IR m+1 in the same
PLC cycle in which the Mode Control Bit is reset to 0.
When the Mode Flag (IR n.00) is OFF, the updating of input data from slaves
1~3, in IR n bits 04~15, has resumed.
