Job number (ANR)
A job number must be allocated to each connection that should be used by Siemens handler
modules. This number is used to access the connection from the PLC program. The job
number together with the frame offset number determines the connection. This precludes
multiple assignments. The job number and the respective frame offset number must be
supplied in the control program.
Range: 1 to 199
Priority
The parameter specifies the priority of the message for the CP143 H1 / TCP/IP. UDP
connections support priorities 1 and 2. Priority 1 is the highest priority.
When establishing a connection, priority 1 and 2 connections are so-called static
connections. This means that the connection will be re-established, if possible, should it
have been terminated (e.g. by the reset handler module).
Jobs with a priority of 1 differ from those with priority 2 in that the job is processed
internally. The size of the user data for priority 1 jobs is limited to the pre-set block size.
Data can not be blocked by means of ALL handler modules.
Range:1to2
Job type
Here you specify the type of job. The following job types are available:
• Send transmission of unstructured data.
• Receive reception of unstructured data.
Type
Here you can specify who should receive the information
• Multicast are connections that are not directed at all participants but only
those that have the same multicast circuit number. You specify the
target group by means of the IP address.
When you select multicast the multicast ID is transferred to the
IP-address.
• Broadcast transmits a single message to all the participants that have been
allocated the pre-set broadcast address or reception of single
messages from participants that transmit via the preset broadcast
address.
The H1 broadcast address is 255.255.255.255.
