Parameters for an H1 Transport-connection
Connection name
You may specify a name for the connection. The name may consist of a maximum of 32
characters.
Frame offset
The frame offset (SSNR-offset) determines the frame from the start address that is used as
communication job by the current job. Frame offsets are normally only used in multi-
processor systems with values larger than zero.
Please use the following values when assigning frame offsets:
• Frame offset 0 for CPU 1
• Frame offset 1 for CPU 2
• Frame offset 2 for CPU 3
• Frame offset 3 for CPU 4
Range:0to3
Job number
A job number must be allocated to each connection that should be used by 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
