Operator Control and Monitoring DevicesSystem interfaces: Text panelsSIMATIC S5■ OverviewDifferent interfaces can be used for linking SIMATIC OP (notOP3) to SIMATIC S5 (not S5-150U) which differ in terms of typeand performance.From the viewpoint of the connected OP, all of them are logicalpoint-to-point connections i.e. an OP is always permanently assignedto a specific PLC. The PLC requires a standard functionblock which must be called for each connected OP (the standardfunction block must be ordered separately).AS511 interface (not OP3)S5-90 to 135U (except CPU 945 and CPU 922 < Version 9,except CPU 928 [6ES5 928-3UA11])The AS511 interface uses the PG interface of the SIMATIC S5and utilizes the corresponding CPU resources i.e. the performanceof the OP depends upon the performance of the SIMATICCPU used.FAP interface (not OP3)S5-115, -135U over second CPU interface(CPU 943B, CPU 944A/B, CPU 945, CPU 928B)S5-95U, -100U over CP 521 (except CPU 100 and CPU 102)S5-115U, -135U, -155U over CP 523 (except CPU 945 and CPU922 < Version 9, except CPU 928 [6ES5 928-3UA11])The FAP interface either uses the free ASCII interface of a correspondingSIMATIC CPU or the interface modulesCP 521/CP 523. The OP must not be connected over the CP 521in the ET 200!Communication between the OP and SIMATIC S5 is based on aspecial FAP protocol which is processed by the standard functionblock of the PLC.Several OPs can be connected to a PLC. The performancedepends on the cycle time of the SIMATIC.PROFIBUS DP interface (not OP3)S5-115U, -135U, -155U over IM 308C or CP 5431 FMS/DP(except CPU 922 < Version 9, except CPU 928[6ES5 928-3UA11], except CPU 946/947[6ES5 94•-3UA11], except CPU 946/947[6ES5 94•-3UA21], except CPU 946/947[6ES5 94•-3UA22] < Version 5)A PROFIBUS DP interface allows• up to 2 OPs to be connected as SLAVES to a SIMATIC S5-95Uwith an integrated PROFIBUS DP/master interface [6ES5 095-8ME01] over a PROFIBUS network.• up to 30 OPs to be connected as SLAVES to a SIMATIC S5with a separate PROFIBUS DP/master interface IM 308C, orCP 5431 FMS/DP.The communication between the OP (DP/slave) and SIMATIC S5(DP/master) is implemented with the help of PROFIBUS DPmessages acc. to EN 50170 with a higher-level FAP protocol,which is processed by the corresponding standard functionblock in the PLC.2Siemens ST 80 · 2006 2/163
