Figure 1-6. Typical Parameters for a Two-Channel SINEC L1 LAN
Explanations of Figure 1-6
• DB number for programmer operation in safety mode ( Figure 1-5)
• Own slave number
Both subunits always have the same number
• Number of elements in SINEC L1 polling list
Enter the number of data paths here.
The SINEC L1 polling list must contain the following elements:
- The numbers of a slave that are sources of data transfers (source slave)
- The numbers of a slave that are destinations of data transfers from the master and have
not already been defined as source slaves.
If several data transfers originate in one slave, it is necessary and advisable to specify the slave
more than once. The same slave numbers should not appear next to each other in the polling
list so that enough time remains for internal slave data processing.
Example: Determining the number of elements in the SINEC L1 polling list
The following data transfers are desired in a network consisting of slave 1, slave 2, slave 3,
slave 4, slave 5 and the master:
- from the master to slave 1
- from slave 1 to the master
- from slave 2 to slave 1
- from slave 2 to slave 3
- from slave 3 to slave 4
- from the master to slave 5
