Standard Mode
The options available primarily depend on the individual project. How-
ever, at the very least, times greater than 100 ms should be prese-
lected. For further information, please contact our support hotline.
5.15.6 Size of the Polling Area
Depending on the data type and operating device, the polling area has
a length of up to 23 bytes. The entry allows adjustment to suit the area
actually used, if you can avoid using the image of the status LED or
part of this. The basic setting for all operating devices is a length of 12
bytes.
5.16 Control Codes
You can use hexadecimal control codes to control special functions on
the operating device. The control codes are transferred to the operat-
ing device using the polling area. The operating device interprets the
control code and subsequently triggers the corresponding function.
The following functions can be requested by the controller:
