Possible alarm responses are:
S PLC Stop : The user program is no longer executed, the NC Ready relay drops out, and
the hardware outputs are disabled ( OUTDS ).
S EMERGENCY STOP: The PLC provides the EMERGENCY STOP signal to the NCK in
the user interface after the user program has been executed.
S Feed disable: The PLC provides the Feed Disable signal to the NCK in the user interface
after the user program has been executed.
S Read–in disable: The NCK provides the Read–in Disable signal to the NCK in the user
interface after the user program has been executed.
S NC Start inhibited: The PLC provides the NC Start Inhibited signal to the NCK after the
user program has been executed.
S SHOWALARM : This alarm has no alarm response (bit0 – bit5 =0).
Priority of cancel conditions

User alarms
The user interface “1600xxxx” provides the user with two sub–ranges for setting a user alarm.
S Sub–range 0: 4 x 8 bits to set user alarms (0 –> 1 edge)
Byte 0 : Bit0 => 1st user alarm ‘’ 700000 ‘’
Byte 3 : Bit7 => 32nd user alarm ‘’ 700031 ’’
S Sub–range 1: User alarm variables
The respective bit (sub–range 0) with a 0/1 edge change will activate a new user alarm. Sub–
range 1 is intended for additional user information.
