Priority
This parameter specifies the priority of the message for the CP143plus. The priority may
range from 0 (highest priority) to 4 (lowest priority).
When establishing a connection, priority 0,1 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).
When establishing a connection, priority 3 and 4 connections are so-called dynamic
connections. In this case the connection is established by means of a job that initiates the
application for the respective connection. Once a connection with priority 3 is established it
exists until it is terminated. The CP will not attempt to re-establish the connection. Priority 4
connections are terminated automatically when the respective message has been transferred.
Range:0to4
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.
• Fetch Aktiv read requested data from another controller.
• Fetch Passiv used for the passive side of the fetch.
• Write Aktiv write the requested data into another controller.
• Write Passiv used on the passive side for a write.
Ethernet address (Adr)
The ethernet address identifies a station. The ethernet address of the station must be unique
within the network. The ethernet address consists of 6 bytes. The first three bytes are specific
to the manufacturer. These bytes are allocated by the IEEE-committee. The remaining three
bytes are supplied by the end-user. The allocation of ethernet addresses are the responsibility
of the systems network administrator.
Transport Service Access Point (TSAP)
Under H1 the TSAPs are used to establish communication channels for a connection. The
length of a TSAP is 8 bytes. TSAP assignments may consist of hex or ASCII entries.
Local TSAP
This is the TSAP of your own (local) station.
External TSAP
This is the TSAP of the destination station (external station).
