Check list for connection addresses
As the multiple use of connection addresses cannot be avoided by technical measures, this
must be achieved using organisational measures, implemented by the user.
Proceed as follows:
1. Calculate the total number of block calls
For each individual device in the overall network, calculate the number of block calls with
Safe Ethernet connection. We recommend using a table as shown in the following exam-
ple:
Number of device Number of block calls
1 2
2 1
3 1
4 -
Total number of block calls 4
2. Calculate connection addresses
Calculate the connection addresses for all point-to-point connections. You should also cal-
culate how often a connection address has been configured. We recommend using a table
as shown in the following example:
Connection address
Configuration as lo-
cal address
Configuration as re-
mote address
1 I I
2 I I
3 I I
4 I I
5 … 255 Not used
Total number of configured connection
addresses
8
3. Complete check list
The following check list must be completed and the results documented:
Question Yes No
Have all devices in the network been recorded?
Have all the block calls on all devices in the network been recorded?
Does each configured connection address occur 1x only as a "local
address"?
Does each configured connection address occur 1x only as a "remote
address"?
