Sending and receiving of information
Send
Each device sends exactly one item of status information with a length of up to 26 bits of
data (C4000 and M4000 senders do not provide any information, this is provided by the
C4000 or M4000 receivers).
The status information is not addressed to a specific user on the EFI string, i.e. all users on
the EFI string can receive the status information.
Receive
The product families differ in the number of items of status information received.
The maximum number of items of status information received and their addresses are
listed in the following table by product family. The table shows the items of status
information received per EFI string.

•
The maximum number of items of status information received defines the number of
devices from which a device can receive information (e.g. C4000 Host from the two
guests and a safety controller).
•
The devices addresses in column 4 define the devices to which a device can be
connected. The C4000 Host receives, e.g., only the addresses 2 and 3 (C4000 Guests)
and 14 (safety controllers or EFI gateways). The connection of an M4000 (1) or an
S3000 (7) is not possible.
•
Also pay attention to the information given in section 4.2 “Firmware compatibility of the
EFI devices” on page 17.
