ModbusTCP Protocols
The IP address of ModbusTCP is the same as that designated by the controller with
a fixed port numbered 502. Function is mainly divided into two sections: the
read-write section, and the read-only&write-only section. Furthermore, the
read-only&write-only section can also be divided into the robot receiving end and
the robot sending end.
Read-only, Write-only variable
By protocol content, the read-only and write-only section are classified into system
protocols and the user protocols.
The system protocols, configured and maintained by developer, mainly to read and
setup the motion parameters or status of robot. Users can only read or write the
fixed variables stored in a designated fixed address.
The user protocols are configured and maintained by users, but only for using
robotic language programming.
Both the receiving end and the sending end have 64 pieces of bool types, 6 pieces of
int type and 24 pieces of float types data interface. Users can read and write the
PLC data from the master station by teaching pendant programming. The mapping
relation between the physical addresses and variables are described in tables 7-2 and
7-3 as below.
