Chapter 8. Communication Functions
8-41
8.2 User Defined Protocol Communication
8.2.1 Introduction
User Defined Protocol Communication allows users who do communication between GM7U main unit and other kind of device
to define the other company’s protocol at GM7U 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, GM7U main unit
executes the communication with the other kind of device through the defined protocol.
For this, protocol frame must be defined in GMWIN. And exact knowledge about the contents of the protocol defined by the
user is vital in making the communication possible. GMWIN can download a user defined protocol frame into GM7U main unit
and it is saved. it is not erased by power’s off/on. For using user-defined mode, he/she should program with instruction
controlling sending of PLC as well as edit frames. This section explains User Defined Protocol Communication setting & usage.
8.2.2 Parameter setting
1) Setting Communications Parameter
(1)
Open a new project file from GMWIN and select GM7U as PLC type
(2)
After setting communication parameter at GMWIN. Double click it to activate this window.
