A bus termination is imperative as soon as the connected gateway is the final user in a Profibus
segment. Make sure that only the first and the last user in the Profibus segment provide a bus
termination.
The bus termination in the arriving D-Sub connector must not be used since it is not actively
terminating the Bus to 0 V and + 5 V.
4.4.4. Gateway projecting in Profibus project
For gateway projecting in the Profibus project there is a GSD file attached that first is to be imported
into the projecting software. Proceed as usual with all other DP slaves and place the bus Node ID set
in the gateway.
For parameterization you have the following options:
Auto Scan SPA
Default: ON
During operation the gateway is automatically and continuously scanning all SPAs connected,
checking whether they are „in position“. If required, this information can be compiled by special
command for read in by Profibus. AutoScan spares the DP master cyclic polling of each SPA itself.
However, there are situations where this feature is not welcome. In this case please refer to the
gateway command “SPA AutoScan ON or OFF“ that has an impact on this function also during
operation.
Auto message SPA position
Default: OFF
If active, in the following situations the gateway will automatically transmit a message without prior
DP master request.
• After all SPAs having been „in position“ before, now at least one SPA is no longer. If further
SPAs are no more „in position“ either, no supplementary message will be transmitted. A
message is also transmitted upon one SPA signalising “error” status.
• After at least one SPA having been not „in position“ before, now all are „in position“ again.
This option is only available with Auto Scan SPA =ON. The message transmitted is identical to the
response on the command „Batched information Check Position“ of block number 20h.
Auto message SPA error
Default: OFF
If active, in the following situations the gateway will automatically transmit a message without prior
DP master request.
• After all SPAs having transmitted „no error“ („in position“ or „not in position), now at least one
SPA is in „error“ status. If further SPAs join, no supplementary message will be transmitted.
• After at least one SPA having been in „error“ status, now all SPAs are „in position“ or „not in
position“.
This option is only available with Auto Scan SPA =ON. The message transmitted is identical to the
response on the command “Batched information Device Status” of block number 20h.
