Hello to all.. i am trying this code… X-Coordinates := a; (From external plc) Y-Coordinates := b; (From external plc) Z-Coordinates := c; (From external plc) VAR Robtarget delta delta.trans.x := a; (From variable a to robtarget trans.x) delta.trans.y := b; (From variable b to robtarget trans.y) delta.trans.z:= c; i am getting an error. I am writing the code in Robot Pendant, and to equate the variable a,b,c with trans.x,trans.y,trans.z values of robtarget , when i use the assign function “:=” and data type Robtarget. I can select robtarget “delta” but how to write trans.x,trans.y,trans.z to move values from a,b,c to robtarget delta. if i select all and write it myself it gives error. If some guidance on how to write and use each value trans.x,trans.y,z.. ---

Are a, b and c declared as num type? After selecting delta, edit, abc. Type .trans.x and such. ---

yes sir.. a,b and c are num type. as the coordinates data from plc is moved into a,b and c. ---

i use the same method as you respectable mentioned, selected delta and edit. when write “.trans.x” etc and equate it with “a”. a:= delta.trans.x it turns the writing “trnas.x” into red colour like wrong syntax or something. ---

delta.trans.x:=a; is correct syntax. Did you make a typo? > [@](#): > > it turns the writing “trnas.x” into red colour like wrong syntax or something. notice in your reply, trnas. Make sure you don’t leave out required . where needed. ---

Sorry for the late reply i was suffering from fever. Sir, that issue is resolved the problem was not with the “trans.x” syntax. In the motion command right after the trans.x, trans.y and trans.z values i have to use “Wobj1” from optional arguments for my job which i was missing. ---

There is a query regarding programming if you kindly give it a check For some numeric value like “4” saved as Input sent from the external plc, if i see the IO tab the value is shown “4” but saving the value in some variable “reg1”, and check the Program data \> “num” reg1 it is 3.999999.. Using this variable in IF command generates an error like " IF reg1 := 4 then" … it always go for the second option “IF reg1 \< 4 then”.. i think Round() function can’t be used in IF condition.. ---

Round it first then.
