[?]: Controller with data logger

[reymond_craig]

Dear Colleagues,

Good day I just want to ask if there is controller or device that we can use for pumping stations to control and log certain variables, alarms and events preferably siemens, or if siemens don't have this other brand is also welcome.
Thank you

Best regards,

There are SIEMENS SIREC Family:

Also, I strongly reccomend ENDRESS+HAUSER.

Thank you for your reply, but I need a logger that can be read by standard office application like excell. This is exactly the scenario, I need to program 5 pumping stations without remote access on central scada. The operator need to get every week the data recorded or alarms using laptop or any hand held device. Thank you in advance

Hi

Maybe if you use a small PLC (S7-200/1200) with OPC connectivity and take the data from the OPC to an xls file (or csv/pdf/etc.)?

IMO this is the best approach, but it involves PC programming.

It can be done with CoDeSys-based PLC (WAGO, OWEN etc.) and special library - SysLibFile. You can create CSV file on PLC flash, and it will be possible to access it from PC. Of course, this CSV can be opened and viewed with Excel.

See this application note.

Also these smart modems look good:

(didn't try them yet).

You can read PLC's variables via Excel if you are using S7-200 and PC Access software.
Or, use Omron CJ1 PLC, capable to store values in CSV format on local MMC, then you transfer files to PC .

Is Siemens logo have capability to log data on its memory card then retrieve it in pc? Thanks, Im more comfortable working in siemens

[Homeroid_BL]

S7-200 only, in recipe form only (No standard formats CSV XLS etc.).

Then you have to wait a new version of S7-1200...

with new version a data logging functionality will be available. Then you can store different values into a CSV-File at PLC. You can download this file via Webserver

If you want to store data from S7 (1200,200,300,400) to csv file, you can use SW S7-Easylog.
