Hi there, I am new to Ignition but very excited to work.

I am unable to read barcode data from Siemens 317 CPU programmed using S7 and trying to read directly in Ignition OPC server.

The PLC has data type as pointer #pDB701.DBX 196.0 which has ASCII values for the barcode in byte 198, 199, 200 and so on.

The data type selected in ignition as String and path as below.

ns=1;s=[CC09]DB701,STRING196.30

The data quality is good but value is blank.

What is the reason?

Can you try the following and post the result?
ns=1;s=[CC09]DB701,STRING196
ns=1;s=[CC09]DB701,I196.0
ns=1;s=[CC09]DB701,I196.1
