Remote node 5 on the CONET network has digital information in DIT registers 5000 to 5007.
The Central Node 2 needs to monitor these digital inputs. A regular update time of every 10s
is quite satisfactory to determine that the remote system is still connected and functioning if
nothing changes, but the data should be sent immediately if any of the digital inputs changes
state.
Node 2 is the Destination node (it sets up the subscription and receives the data). Node 5 is
the sending node, and requires no user configuration to participate in the subscription
process.
Fill in the following data into one of the eight subscription blocks in the Subscription Table in
the P3 CPU of Node 2 to configure this function:
NAME
VALUE
DESCRIPTION
Change of State Required
Yes
The data will also be sent whenever any bit the DIT
registers in the range 620-627 changes.
Update Time
10
The regular updates can be 10 seconds apart.
Local Port Number
0
The CONET network is Port 0 on the CPU
Destination DIT Start Address
6000
This is the DIT Address where we want to start writing
the received data.
Source Node Address
5
The local CONET Node Address on the Conet network
Source DIT Start Address
5000
The Source Data start at DIT address 620
Data Range
8
We require 8 DIT registers to be sent
Table 8.2 Subscription Block Data Example
When configured, Node 2 automatically requests a subscription with the following data from
Node 5 on the Conet network connected to the CPU:
Node 5 undertakes to send the contents of its own DIT registers 5000 to 5007 over the
network to node 2 whenever any of the registers changes or every 10s if no change occurs in
that time. The information will be placed in node 2's DIT registers 6000 to 6007.
Node 2 can monitor the status of the subscription by monitoring the relevant bit in the
Subscription Status DIT register. If this bit is clear then the subscription is operating
successfully. If this bit is set, then the subscription has failed and received data is not valid,
or the subscription has not been correctly set.
