Table 3b: Constants for calculating the slot time at DP/FMS (”universal“)
and DP with S5 95U (redundant optical ring)
The calculation of the slot time only takes into consideration the optical network and the connection of bus sub-
scribers to the OLM via an RS 485 bus segment with a respctive length of max. 20 m. Longer RS 485 bus segments
must be allowed for by adding them to the Length
OF
.
Note:
When the slot time is configured with a too small value the OLM will, through it’s fault function and fault indications,
indicate such. The System-LED will blink red/green.
1)
Using the OLM/G11-1300 and OLM/G12-1300 at data rates of 12 MBit/s, 6 MBit/s, 3 MBit/s and 1.5 MBit/s the
minimum slot times according to the following table must be met.

Table 4: Minimum slot time on OLM/G11-1300 and

Use the values from Table 4 if the calculated slot time is smaller than the minimum slot time indicated in the table.
