6. Then enter the AS-i parameter bits at Slave 1:
P1 (bit 1): Extended process image
The extended process image contains important parameters (see the table titled
Parameter overview (Page 116)). Transfer can be activated or deactivated using P1.
P2 (bit 2): In addition to the extended process image, parameters can be transferred
acyclically via data sets (see the table titled Parameter overview). You use P2 to
determine whether the M200D AS-i Standard waits for the parameter assignment data
set on startup. (Default: Motor starter starts up without startup data sets.)
Note
If parameter bit P1 (bit 1) is activated and, therefore, the extended process image is
deactivated, the analog addresses (extended process image) are not visible in the
controller. In this case, settings in the analog data field (7) have no significance.
7. Entering analog addresses
The extended process image uses the AS-i mechanism for transferring analog data (for
details, refer to the manual for the AS-i master). This data can be exchanged between the
PLC and AS-i master either cyclically or acyclically. If you are using the cyclic transfer
method, place a checkmark in the "Cyclic analog data" box. In the "Inputs" and "Outputs"
entry fields, specify the address range for the analog data in the PLC address space.
- Cyclic transfer of I/O data
Select cyclic analog data.
Enter the required analog address, e.g. 256. You can use the "Cyclic analog data" check
box to activate or deactivate access to analog data via I/O commands.
In the program, you access the analog input value of the first channel (IN1) using
command L PIW256 and an analog output value (OUT1) using command T PQW256.
The other channels of the module are located at the subsequent addresses, e.g. 258,
260, etc.
- Acyclic transfer of I/O data
If the "Cyclic analog data" check box is deselected, then the analog values are accessed
via data sets. Therefore, the "Cyclic analog data" check box should not be selected if the
analog outputs of an AS-i slave are written via acyclic services.
Slave 1 has now been configured.

Field Value
P bit 0 —
P bit 1 0: Extended process image activated
1: Extended process image deactivated (default setting)
P bit 2 Wait for "Parameter" startup data set
0: Yes, starter waits for parameter data set
1: No, starter starts up and uses the most recently valid parameter data set (default
setting)
