If you want to set the number of the chosen assembly, you have to set the attrib-
utes 14 and 16 in the corresponding instance of the connection object.
To set this value, the connection has to be allocated, but the EPR attribute
has not to be set to any value.
• Read a configured assembly (addresses as specified above):
Get single request:
ID Message Body
414 00 0E 05 02 0E get produced connection path (Request
for input assembly by master).
Get single response:
ID Message Body
413 00 8E 20 04 24 05 30 03 response from slave
The addressing format of the attribute values differs from the normal mode. A
connection path attribute that specifies class 4, Instance 5, and attribute ID 3 is
illustrated below:
Class #4 Instance #5 Attribute #3
20 04 24 05 30 03
The instance defines the assembly you want to use. This format has to be used
by the master in the request and is used by the slave in the response.
• Set the input assembly 04 for a Poll Connection (addresses as specified
above):
Set single request:
ID Message Body
414 80 00 10 05 02 10 20 04 first fragment
414 80 81 24 04 30 03 second fragment
Because the message body is longer than 8 bytes, the fragmented protocol has
to be used.
Set single response:
ID Message Body
413 80 C0 00 response on first fragment
413 80 C1 00 response on second fragment
