PLC Type? How much data? Which format?

[ahsan1820]

PLC Type? I think any of the Micro PLC can be used for the following task. How much data? Load cell data for each dump.water quantity used in single cycle,plant start and stop time.daily usage of material from dump and water used per day. Which format? format can either be 3excel sheet or any other suitable one

And what are your computer programming capabilities? There isn't any easy interface for the micro PLC's that can log data to excel (or others). You say VBScript, but can you use Visual Basic. With visual basic you could use a FX PLC and MX Components (ActiveX control from Mitsubishi)...

I have good programming capabilities in Ladder Logic but bad in scripting ,yes you are right Visual Basic is a good option ,please tell me how can I read data from FX plc to Visual Basic application

Check out MX Sheet...

[ahsan1820]

I have to purchase MX sheet,as according to my knowledge it is licensed software . tell me the way if i can read serial data from PLC on port of PC via Visual Basic

Well, then you'll have to program the MX protocol yourself in VB using serial comport. Not an easy task - you'll spend a lot more hours trying to program the MX protocol instead of just purchasing MX Sheet....
