I am still having trouble understanding the scope of EMC/Classic Ladder. It would be nice to have an introduction presenting why someone that knows nothing about EMC/CL might want to learn more about it. So far, my understanding is that CL provides a ladder programming language with HAL links such that procedures can be expressed in ladder language form and linked to EMC IO. So CL has two roles. One as a scripting language, the other, as a software PLC. It seems the Mazak tool changer is an example is of this. One element of confusion, is the role of the Modbus feature. I get the impression that Modbus is usually used to communicate with hardware PLC's. What is the nature of that communication? Would it be more appropriate to separate the scripting language from the PLC? -- Kirk Wallace (California, USA http://www.wallacecompany.com/machine_shop/ Hardinge HNC lathe, Bridgeport mill conversion, doing XY now, Zubal lathe conversion pending) ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
