I am looking to communicate to a Omron CQM1 for the purpose of changing counters. We usually do this with the Data Access Console. I have purchased a CQM1-C1FO2 com cable with the intentions of developing a VB program to change the counters. Are there free programs already out there for this purpose? Where can I find documentation on Sysmac Way for this application? Any help would be greatly appreciated.
 
Here is a beginners code

This small VB app was supplyed to me by

That was 6 years ago but I found it very usefull to at least begin to dev. some more elaborate code.

Here is his comments on it :

Brief instructions:

1. Select the serial port and click Set.
2. Type in a command, not including FCS and *CR.
3. Click Go. FCS will be calculated and command will be sent. Response will
be shown below.

NOTE: The default text in the Command box is the PLC model read command. If
you just click Go, the response should show the model code (11 for CPM1A):
The entire text will be: @00MM001140* .

Hope this is helpful. Let me know if you have any more questions.

Note: This is given to you with no guarantees, as a friendly gesture. No
support is implied. This is not an official Omron release. No liability
will be assumed. Please don't sue me!
This is meant as a starting point; not an application unto itself.

As you can see he was a thrue gentleman and help me when I needed it.

Hope this can help you tooooo!!!
 
For some reason I cannot get on but if you go to www.mrplc.com - select downloads - select Omron there is a wealth of information there including a VB Host Link example.
 
Dear Sir,

I m using omron CP1H plc with vb6.0 through rs232 communication
I m getting response from plc but i want read perticuller memory area , like D100 .... Now I m using "@00RD00000100" + fcs + * and chr(13)
and i m getting from plc result is more than 30 words but i want read a single word??? So please tell me that how i can do it???
thank you!!!!!
 
Unfortunately that ActiveX is for CV Mode Host Link (FINS) only, and does not work for CQM1, which uses C Mode Host Link only.
There is lots of code available on MrPLC for C Mode Host Link commands.
If you can provide more specifics, I can help with the VB code.

PMCR, the original post (back in 2005!!) was for CQM1, this latest one was for CP1H, so all should work, providing that pankajs1985 has a serial port...
 
Ooooops

Sorry about that. You are absolutely correct.
I need to stop reading from a Blackberry. I miss the important details.

That ActiveX control is perfect for CP1H / CP1L.
