Indramat SERCANS SCS-P
The SERCANS SCS-P is a SERCOS master card for up to eight axes. It is supported as both an ISA and a PCI type.
The DPRAM of the SERCANS SCS-P is 4 Kbytes. An interrupt is used, which actuates the card and is also used for synchronising functions in the TwinCAT system.

Address: ISA: Enter the DPRAM card address here. This address is jumped on the card and can assume the following values: from 0xC0000 to 0xEF000 in steps of 0x1000
PCI: Shows the PCI slot number, the PCI interrupt and the DPRAM address.
Search: Used to search the computer for SERCANS cards of the corresponding type (ISA / PCI).
Cyclic IRQ: Enter the cyclical interrupt used. It must coincide with the card setting (jumper, ISA only). The non-cyclical card interrupt is not required and may not be jumped on the card (ISA only).
Sync Master: See ”Synchronizing Several SERCANS Cards”.
Phase 4: Used to specify whether the card should StartUp in phase 4 at the TwinCAT system StartUp. It will otherwise remain in phase 2 and can be switched to phase 4 at a later point via ADS.
Synchronising Several SERCANS Cards
If you require more than eight axes, you will need to use 2 or more SERCANS cards. These cards must be synchronized with one another since only one card can control the TwinCAT system. The card which synchronizes the TwinCAT system is described a ”Sync Master” and the corresponding check box for this card should be ticked (none of the others). The synchronizing process is different depending on whether you are using ISA or PCI cards. You cannot mix ISA and PCI cards in one installation!
Synchronizing ISA cards
In the case of the ”slave” cards, you should set the same cyclical interrupt as for the ”master” card. Otherwise, break the J100 connection on the back of the card (including the track)! J100 is to be found on the back, next to the inserted interrupt jumpers. If the card is to be used as a master at a later point, re-solder J100.
Synchronizing PCI cards
In the case of PCI cards, synchronisation is carried out via a 10-pin ribbon cable (angled ribbon cable socket on the top), which is used to connect all SERCANS cards in parallel. On the ”master” card you also need to connect a jumper on J108 between PIN 1 PIN 2. This jumper is not required on the ”slave” cards.
