1.9.2 Addressing NC variables
Addressing the NC variables starts with the path section nck.
This section is followed by the data address; its structure should be taken from the List Manual
NC Variables and Interface Signals.
Example:
<LET name = "tempStatus"></LET>
<OP> tempStatus ="nck/channel/state/chanstatus" </OP>
1.9.3 Channel-specific addressing
If no channel number is defined in the address token, access is always to Channel 1 of the
operating software.
If it is necessary to read data from a specific channel, the identifier u (Unit) with the desired
channel number is added to the address.
Example:
nck/Channel/MachineAxis/actFeedRate[3]
nck/Channel/MachineAxis/actFeedRate[u1, 3]
1.9.4 Generating NC/PLC addresses during the runtime
It is possible to generate an address identifier during runtime.
In this case, the content of a string variable is used as address in an operation statement as
well as in the nc.cap.read and nc.cap.write functions.
Observe the following for this type of addressing mode:
● Write the variable names in quotation marks.
● Use three ‚$’ characters as prefix for variable names.
Syntax:
"$$$variable name"
Example:
<PRINT name="var_adr" text="DB9000.DBW%d"> 2000</PRINT>
<OP> "$$$var_adr" = 1 </OP>
