PHM-7740 Imojuli yokufaka ye-analog yamatjhaneli amane
Ukuhlolisisa umkhiqizo
Ingatjhugulula amatshwayo we-4-channel RTD/TC/Resistor/mV avela emkhakheni wezebubulo ukuya kumatshwayo wedijithali, begodu ngokuya kwephrothokholi ye-MODBUS, ngokusebenzisa i-RS 485 yokuthintana inikela amatshwayo wedijithali ku-PHM-7100, i-PLC nofana iinlawuli zekhomphyutha nofana iinhlelo zokuthola idatha. Nawuqathanisa nendlela yokuphuma yesiginali ye-PLC+, yehlise amaphutha ngokuguqulwa kabili, ingakhuphula khulu ukunemba kokuguqulwa ngesikhathi esifanako ikhulise ukuzinza nekghono lokulwisana nokuphazamiseka.

Ubunjalo bomkhiqizo
- Idizayini yokusetjenziswa kwamandla aphasi, ukutjhuguluka kwezinga lokutjhisa eliphasi, ukulinganisa okuzenzakalelako.
- Ihlukaniswe ngokupheleleko hlangana namatshwayo wokufaka amatjhaneli amane/ukuthintana/ukuphakelwa kwamandla
- Sekela iplagi etjhisako
- Iphrothokholi yokukhulumisana ye-MODBUS RTU iyasekelwa, begodu izinga lokukhulumisana liphezulu ukuya ku-115200bps.
- Sekela ukuphakelwa kwamandla nokukhulumisana ngeendlela ezimbili: isitimela sokufaka ngemuva kanye netheminali.
- Ihlanganiswe isetjenziswa ne-PHM-7100 ukusekela i-MODBUS TCP/IP, ukwenzela bona kube lula ukufakwa nokugcinwa, begodu nokwenza ngcono ukusebenza kokudluliswa kwedatha.
- Isiginali ngayinye yokufaka ingasethwa ngokusebenzisa ihlelo: amasignali we-RTD/TC/Resistor/mV
