jplc

Thank you very much for the information, but if I want to send these FINS commands to PLC, I'll need a program like an ActiveX control that includes e.g. rawFINS command, won't I?. For example, I could use Cx Server Lite. would it be possible to communicate with PLC only using Comport Delphi Component or through AT commands?

Thanks for the information, but I think these commands are used with CX-Programmer, aren't they? what I am looking for, if it's possible, is the way of access to data stored in memory card, with an application built in delphi or Visual Basic. I connect to PLC via modem. The configuration is: Network type: SYSMAC WAY, CPU Type: CJ1M. Thanks in advance.

I'd like to know if it's possible to read Historical Data from Memory Card to allow us to access with an external application via OPC. Thanks in advance.
