8.2 User Defined Protocol Communication
8.2.1 Introduction
User Defined Protocol Communication allows users who do communication between K7 Basic Unit and other kind of device to
define the other company’ s protocol at Kseries PLC. There’ re a number of kinds of protocols made by many companies, that it’ s
difficult to have all protocols in it. So if a user defines a protocol that can be applied to his/her purpose, K7 Basic Unit executes the
communication with the other kind of device through the defined protocol. For this, protocol frame must be defined in KGLWIN (Version
2.0 or higher). And exact knowledge about the contents of the protocol defined by the user is vital in making the communication
possible. KGLWIN (Version 2.0. or higher) can download a user defined protocol frame into K7 Basic Unit and it is saved(it is not
erased by power’ s off/on). But protocol frames are damaged to download with changes of parameter, or to fail to back up the data,
caused by lower back-up battery voltage than the standard. For using user-defined mode, he/she should program with instruction
controlling sending of PLC as well as edit frames. This section explains UDPC setting & usage.
