Mō te whakawhānui whānui i te I/O

Mō te whirihora i ngā hanganga I/O tohatoha

Aratau Isochronous i runga i te PROFIBUS

E hiahiatia ana he Kāri Mahara Iti SIMATIC mō te whakahaere i te PTM.

Tono

Ko te CPU 315-2 DP he CPU me te mahara hōtaka rahi-waenga ki te nui me te atanga matua/pononga PROFIBUS DP. E whakamahia ana i roto i ngā tipu kei roto ngā hanganga aunoa tohatoha me te I/O pokapū.

He maha ngā wā ka whakamahia hei matua paerewa-PROFIBUS DP i roto i te SIMATIC S7-300. Ka taea hoki te whakamahi i te CPU hei matauranga tohatoha (pononga DP).

Nā ō rātou hanganga rahinga, he tino pai mō te whakamahi i ngā taputapu hangarau SIMATIC, hei tauira:

Te hōtaka me te SCL

Te whakarite i ngā taahiraa mīhini me te S7-GRAPH

Hei tāpiritanga, he tūāpapa tino pai te CPU mō ngā mahi hangarau māmā e whakatinanahia ana e te pūmanawa, hei tauira:

Whakahaere nekehanga mā te Whakahaere Nekehanga Māmā

Te whakaoti rapanga whakahaere porowhita-kati mā te whakamahi i ngā poraka STEP 7, i te pūmanawa whakahaere PID paerewa/whakarerekē rānei

Ka taea te whakatutuki i ngā tātaritanga tukanga whakarei ake mā te whakamahi i te SIMATIC S7-PDIAG.

Hoahoa

Kei te CPU 315-2 DP ngā mea e whai ake nei:

Pūtukatuka iti;

Ka tutuki i te tukatuka te wā tukatuka tata ki te 50 ns mō ia tohutohu rua me te 0.45 µs mō ia mahi pūwāhi-mānu.

256 KB te mahara mahi (e rite ana ki te 85 K ngā tohutohu);

Ko te nui o te mahara mahi mō ngā wāhanga hōtaka e tika ana mō te whakahaere ka whakarato i te wāhi nui mō ngā hōtaka kaiwhakamahi. Mā ngā Kāri Mahara Iti SIMATIC (8 MB te mōrahi) hei mahara kawenga mō te hōtaka ka taea te penapena i te kaupapa ki te CPU (me ngā tohu me ngā kōrero) ā, ka taea hoki te whakamahi mō te pupuri raraunga me te whakahaere tunu kai.

Te kaha whakawhānui ngāwari;

mōrahi 32 ngā kōwae (whiringa taumata-4)

Atanga maha-ira MPI;

Ka taea e te atanga MPI whakauru te whakatū i te 16 hononga i te wā kotahi ki te S7-300/400, ki ngā hononga rānei ki ngā taputapu hōtaka, ki ngā PC, ki ngā OP. O ēnei hononga, kotahi mō ngā taputapu hōtaka, ko tētahi mō ngā OP. Mā te MPI ka taea te whakatū i tētahi whatunga māmā me te 16 ngā CPU mōrahi mā te "whakawhitiwhiti raraunga ā-ao".

Atanga PROFIBUS DP:

Mā te CPU 315-2 DP me te atanga matua/pononga PROFIBUS DP ka taea te whirihoranga aunoa tohatoha e tuku ana i te tere teitei me te ngāwari o te whakamahi. Mai i te tirohanga a te kaiwhakamahi, ka rite te whakahaere i ngā I/O tohatoha ki ngā I/O pokapū (whiringa rite, wāhitau me te hōtaka).

E tautokona katoatia ana te paerewa PROFIBUS DP V1. Mā tēnei ka whakarei ake i te āheinga tātaritanga me te whakapūtātanga tawhā o ngā pononga paerewa DP V1.

Mahi

Te tiakitanga kupuhipa;

Mā te ariā kupuhipa ka tiakina te hōtaka kaiwhakamahi mai i te urunga kore mana.

Whakamunatanga poraka;

Ka taea te penapena i ngā mahi (FC) me ngā poraka mahi (FB) ki roto i te CPU i roto i te āhua whakamuna mā te S7-Block Privacy hei tiaki i te mōhiotanga o te taupānga.

Pūrere tātaritanga;

Ko ngā takahanga hapa me ngā takahanga taupatupatu whakamutunga e 500 ka rongoatia ki roto i tētahi pūpare hei tātaritanga, ā, ko te 100 o ēnei ka rongoatia kia mau tonu.

Tārua raraunga kore-tiaki;

Ka tiakina aunoatia e te PTM ngā raraunga katoa (tae atu ki te 128 KB) mēnā ka motu te hiko, kia wātea tonu ai ngā raraunga ina hoki mai te hiko.
