Machine Tool →PLC Address (X)The X addresses of CNC are divided into two types: The 1st type is mainly distributed togeneral-purpose I/O interface of CNC, which includes the fixed addresses and definable addresses; the 2nd

type is distributed to input button of the machine tool panel. The mapping address of X input signal, it isbetter to refer to the User Manual of each system (Installation Connection).

PLC→Machine Tool Address (Y)The output signals of the CNC are divided into two types: The 1st type address is mainly distributed togeneral-purpose I/O interface of CNC of which its functions of these signals can be customized by user.The 2nd address is assorted to indicator of the machine tool operational panel. As the Y output signalmapping address, refer to the User Manual (Installation & Connection) of each system.

PLC→NC Address (G)G signal is the one from PLC to CNC; generally, it is sent the required signal or state signal to CNC.These signals are set by PLC program, which are read periodically and it is defined by CNC system.

NC→PLC Address (F)

F signal is the one from PLC to CNC; commonly, it is sent the state signal or indication to PLC. These signals can be replaced or cleared by CNC instead of the PLC program, which are defined by CNC system.

Internal Relay Address (R)R register is regarded as intermediate logic coil, which is used to save the imtermediate calculation state instead of the external electric input/output. R address is treated as single byte one, its data length is 8-bit. The R register is cleared when the CNC is turned on.

Information Display Requirement Address (A)A signal is the one issuing to CNC from PLC, which is used for the requirement display information, forexample, its PLC alarm, PLC caution, etc., as well it can be set and reset by PLC program. An address issignle byte one, its data length is 8-digit. The address A is cleared when the CNC is turned on.

Hold Relay Address (K)This address is used for holding the relay and setting the PLC parameter, its data will be memorizedwhen the power is turned off. Usually, the K register is used for the PLC parameter and power-down savingstate in the PLC; these registered can be not only modified (other than K0~K9) manually, but also replaceor reset by PLC program. K address is single one; its data length is 8-bit.

Counter Address (C)This address area is usded for storing the current counting value of the counter, the data holds whenthe power is turned off. C address is 4-byte address and its data length is 32-bit.

Counter Presetting Value Address (DC)This address area is usded for storing the presetting value of the counter, the data holds when thepower is turned off. DC address is 4-byte address and its data length is 32-bit.

Timer Address (T)This address area is usded for storing the current numerical value of the timer. T address is 4-byteaddress and its data length is 32-bit.

Timer Presetting Value Address (DT)This address area is usded for storing the presetting value of the timer, data holds when the power isturned off. T address is 4-byte address and its data length is 32-bit.

Data Table Address (D)

D0000～D029 address are cleared when the CNC is turned on. D0300～D0999 area data arememorized when the data is turned off. The D address space is slightly different depending on the systemtype; D address of GSK980TDb or GSK980MDa is single type one and its data length is 8-bit. If it regardsas 4-byte address, its data length may 32-bit.

Label Addresses (L)It is used to specify the label of jump destination in JMPB instruction and the label of LBL instruction.Address range: L0～L9999

Subprogram Numbers (P)Subprogram numbers are used to specify destination subprogram numbers in the CALL and SPinstructions. Address range: P0～P9999
