1. The X address is assorted with the three I/O input terminals, namely, XS40, XS41 and
XS42.
2. The X address is assorted with the input button on the MDI panel of the system.
3.1.1 X Address on I/O Input
The addresses (48 addresses) are defined as INT8U from X0 to X5, which are distributed on
the three I/O input terminals, for example, XS40, XS41 and XS42.
Users can define the signal significance of the X address of the I/O ports based upon the actual
cases, which can be connected the machine tool and compiled the corresponding ladder diagram.
Refer to the appendix one (GSK218MC CNC system PLC I/O address) and the configuration and
definition of the internal software components for the initial definition of the input address.
3.1.2 X Address on MDI Panel
There are 11 types from the addresses X20 ~ X30 of which these addresses are corresponding
with the button input on the MDI panel one by one. User can not modify its signal definition. The
buttons on the MDI panel should be firstly responded by CNC, and then conveys the X signal to
PLC.
The corresponding relationships are shown below:
