Safety ! Before installation: Read this manual completely and gather all information on the unit. Make sure that you understand it fully. Check that your application does not exceed the safe operating specifications for this unit. This unit should only be installed by qualified personnel. This unit should be built-in to an apparatus cabinet, or similar, where access is restricted to service personnel only.
Note. Fibre Optic Handling Fibre optic equipment requires careful handling as the fibre components are very sensitive to dust and dirt. If the fibre is disconnected from the modem, the protective plug on the transmitter/receiver must be replaced. The protective plug must be kept on during transportation. The fibre optic cable must also be protected in the same way. If this recommendation is not followed, it can jeopardise the warranty.

Data from the PROFIBUS master is received at the ODW-710-F2 electrical port (as indicated by the DPR LED). The data rate is automatically detected (as indicated by the BA LED) and data bits are retimed according to the determined rate and sent out on the optical fibre at CH 1. The first ODW-710-F2 ring member receives data at optical fibre CH 2 (as indicated by the FR LED). The data rate is automatically detected (as indicated by the BA LED) and data is sent out on the electrical port.
Calculating system processing delay Data exchange between a PROFIBUS DP master and slave via ODW-710-F2 fibre optic link will be delayed due to the length of the optical fibre and the signal processing within the ODW-710-F2. The signal processing delay is dependent on the data rate, and the fibre delay is dependent on the total length of the optical fibre. The additional time resulting from the optical fibre and ODW-710-F2 is the Overall system delay. Delay @ < 1.
Reconfiguration time under faulty condition The reconfiguration time is determined by the time it takes to detect a faulty fibre segment plus the time it takes to transport an error status message through to the ODW710-F2 focal point unit. The time to transport an error status message to the focal point unit is dependent on how many units the error status message has to be repeated through and the total fibre length delay.
About the interfaces Power The power terminal has two independent inputs, +VA and +VB, allowing redundant power input. The ODW-710-F2 power supply is galvanically isolated from all other interfaces. Optical fibre interfaces ODW-710-F2 uses Small Form Factor Pluggable (SFP) transceivers. This means that a wide range of different fibre transceivers and connectors can be used (see page 12–13). PROFIBUS DP interface The PROFIBUS DP interface is a female 9-position D-sub.
About the automatic data rate detection ODW-710-F2 automatically detects the data rate by monitoring incoming PROFIBUS data frames on both the electrical and optical interfaces. When the data rate has been established the BA LED will go active. If no data frames are transmitted for a period of time the automatic data rate detection will restart and the BA LED will go inactive. The idle time before the automatic data rate detection restarts is set using DIP-switches S2:4 and S2:5.
