KND CNC

The KND CNC driver accesses KND K2000, K1000 C/Ci/F/Fi, and K1000TTCi series CNC systems via HTTP protocol, enabling real-time collection of various device operation data, including program name, spindle override, operating status, PLC points, etc.

For the generic steps, see Create a Southbound Driver and Groups and Tags.

PLC Data

Address Format

AREA ADDRESS[.BIT][.LEN]

Identifier	Description	Type	Permission
X	DI Input	all	Read
Y	DO Output	all	Read
F	NC -> PLC	all	Read
G	PLC -> NC	all	Read
R	PLC Internal Control Relay	all	Read/Write
S	PLC Internal Special Flag	all	Read
K	PLC Internal Power-On Relay	all	Read
D	Data Table	all	Read
TL	Label Sequence Number	all	Read

TIP

Currently, only part of the R area can be set, i.e., R17000-R17099, and it requires explicit permission in the ladder diagram. The ladder diagram must set G138 to 181 to allow remote modification of the above R area.

AREA ADDRESS[.cur/conf]

Identifier	Description	Type	Permission
T	Timer	int32/uint32	Read
C	Counter	int32/uint32	Read

TIP

When reading timers and counters, you need to specify whether it is the set value or the current value.
