Saya sedang mengerjakan project dengan menggunakan Control Expert dan M340, bagaimana cara membaca device luar yang mempunyai komunikasi modbus TCP
PLC address : 192.168.0.10 (internet_1)
device yg akan di baca adalah gateway multi sensor dengan addres 192.168.0.201
slave adress 1 dan addressnya 40005,40013,40021 dengan hasil pembacaan sebelumnya (menggunakan modscan32)
untuk pembacaannya saya menggunakan read_var
dengan
En = Startmb --> internal register bool
adr = addm('0.0.3{192.168.0.201}TCP.MBS')
OBJ = '%MW' --> 40XXX
Num = 40005 --> registry address
NB = 20 --> number of data
Gest =mbuscmd (array 1-4 Int)
berikut table pembacaannya
pembacaan buffernya seperti tidak terbaca walaupun seperti sudah ada aktifitas/transaksi pada mbuscm[1].
apakah karena belum di masukan addres slave nya?
di mana saya bisa memasukan address slave/ device ID nya,ya?
Tolong bantuannya,ya.
