Weigh scale with RS-232 Protocol

[Pradeep Mane]

Hello,

I am trying to connect Shimadzu TX423L load-cell weigh system to V350 plc through RS-232 Protocol

Communication is done and i am getting ASCII string into serial Monitor RX------ refer attachment of monitor screen

But i tried to read into scan protocol but there is know value into ASCII element linked MI/ML,tried with different length as well

I have simple initialize com port, configure protocol, Scan FB,and buf fer reset in my code...tried by creating  variable with stream as well as numeric 

I have attached Weigh system manual snap with data format  for  reference

Using PLC comp port 1 set to RS-232 Protocol as well

But not able to read the values in plc scan protocol

Please help ....Thanks😊

hello Kratmel

Data is receiving into Monitor window of plc but not able to read by protocol into PLC even after using stream with different length

What else i need to try

Thanks 😊

Please post your protocol project.

You can use Stream Protocol configuration embedded to Prot FB project in above topic.

For online testing i use addon com port  or ethernet card.  It is really hard to configure protocol with only one PORT.

Hello,

Unfortunately we have only one com port ...

Stream protocol used and according to data from RX monitor window of V350 data frame structure is 13 byte 

So i have configured 7 MI in stream configuration

Attached code for your reference..

Thanks😊...........

Message go to MI500-vector and then copy to MI50 buffer.

MI50 buffer placed on screen. Refresh button only for test.
