=                Assign a 32-bit local TML variable with data got from another axis

Syntax                        

Operands        VAR32x: long variable VAR32x

               Axis: an integer 1 to 255 representing the Axis ID of the source axis

DM: data memory operand

TypeMem: memory operand. One of dm (0x1), pm (0x0) or spi (0x2) values

(VAR16x): contents of variable VAR16x, representing a 16-bit address of a variable

Binary code

Remark: If the TML variables from the remote axis are user variables, these must be declared in the local axis too. Moreover, for correct operation, these variables must have the same address in both axes, which means that they must be declared on each axis on the same position. Typically, when working with data transfers between axes, it is advisable to establish a block of user variables that may be the source, destination or pointer of data transfers, and to declare these data on all the axes as the first user variables. This way you can be sure that these variables have the same address on all the axes.

The memory location can be of 3 types: RAM for data (dm), RAM for TML programs (pm), EEPROM SPI-connected for TML programs (spi).

One instruction uses a 9-bit short address for the source variable. Bit value X specifies the destination address range:

All predefined or user-defined TML data are inside these address ranges, hence these instructions can be used without checking the variables addresses. However, considering future developments, the TML also includes assignment instructions using a full address where the destination address can be any 16-bit value. In this case destination variable is followed by “,dm”.  

Execution        Copies a 32-bit value from the remote source to the local destination

Example1        

long VarLoc, VarExt;

…

VarLoc = [15]VarExt;

Example2        

long VarLoc, VarExt;

...

VarLoc = [15]VarExt, dm;

Example3        

long VarLoc;

int pVarExt;

...

VarLoc = [15](pVarExt), dm;

Example4        long VarLoc;

int pVarExt;

...

VarLoc = [15](pVarExt+), dm;
