The "cutoff" can be separately set for each slot with the command "SetRe-
motePiSize" (see Appendix 6.3.4.1).
To set up specific devices for slots, use the command "AllowRemoteDevice"
(see Appendix 6.3.5.26) together with the MAC address of the target device. If
no device is to be set up for the slot, use instead of a valid MAC address the
address 0:0:0:0:0:0. Only those slots in which valid MAC addresses are en-
tered can be activated (linked) (see Appendix 6.3.5.28, BindRemoteDevice).
The configuration of the display of a slot in the process image by "cutoff" is
completely independent of this.
The number of bytes before the start of a slot is called its offset. The offset of
a slot in the process image of the master may vary depending on the configu-
ration. The offset for any slot can be calculated with the following formula:
The two additional allowed bytes are the control/status byte and the internally
used byte. All commands that change the slot width or the assignment of de-
vices to slots can only be used in the configuration mode. The position of the
data of a remote device in the local process image is therefore unchanged in
communication mode.
