Xinje XD Series User Manual

11
XD/XL series PLC support “Stop PLC when reboot” function. When there is a serious
problem during PLC running, this method can stop all output immediately. Besides, if the
COM port parameters are changed by mistake, this function can help PLC connect to the PC.
XD/XL series PLC has many communication modes, such as Modbus-RTU, Modbus-ASCII.
When the COM port parameters are changed, the new parameters will be valid immediately
without restarting the PLC.
Wait time can be added before Modbus instructions.
1-2 Programming Language
1-2-1 Type
XD/XL series PLC support two types of programming language:
Make the program with instructions directly, such as “LD”, “AND”, “OUT” etc. This is the
basic input form of the programs, but it’s hard to read and understand;
E.g.: step instruction operand
Make sequential control graph with sequential control signal and soft components. This
method is called “Ladder chart”. This method uses coils and contactors to represent sequential
circuit. The ladder chart is easy to understand and can be used to monitor the PLCstatus
online.
E.g.:
X0 X2
Y5
Y5

The two kinds of programming language can be transformed to each other.
