4-5 Setup Mode
In Setup Mode, as opposed to the standard Configuration / Protected Modes,
the AS-Interface master will:
-
continue to exchange I/O data with all detected slaves.
- stop transferring output data for slaves 1~7 and input data from slaves
1~3 between the AS-Interface master and the host PLC.
- allow the user to send configuration commands from the PLC to the AS-
Interface master.
This effectively means that the output data that the master sends to slaves
1~7 is static, and equal to the last data received form the PLC before
changing to Setup Mode. Input data from slaves 1~3 is still collected by the
master, and stored internally, to be transferred to the PLC when leaving
Setup Mode.
It is recommended to use Setup mode only during installation, commissioning
and maintenance activities, while the controlled machinery is not in operation.
Setup Mode allows the user to configure an AS-Interface system without the
necessity of additional configuration tools. Functions accessible to the user
only in Setup Mode are:
•
Reading and writing of the ’permanent’ configuration data in the master.
Each projected slave’s ID Code and I/O Configuration are stored in non-
volatile memory in the master. This permanent data defines the projected
slave configuration, which the master will use to check against for errors
in the actual, detected configuration.
Additionally, each slave’s projected parameter values can be read and
written.
•
Reading of configuration and parameter data, and writing of address and
parameters of any slave actually connected to the AS-Interface network.
Setup Mode can only be entered if the CQM1-ARM21 is set to Configuration
Mode with the MOD switch (switch 5).
4-5-1 Command Area
In Setup Mode, the first two output words allocated in the CPU are used to
transfer a specific command to the master unit.
