String to number conversion and checking the reachability in RAPID

pion3k

Hello,

I need some help with the following problems:

1) Is it possible to somehow convert a string (in my case received through a socket) to the equivalent data but in a number type in RAPID? I have tried with StrToByte but the problem is that I'm significantly limited by the range of the byte type (0 - 255 without negative values). What I need is to send by the socket the position of the robotic arm and, as you know, the position of the effector can quite a bit exceed the limit (255). I thought about multiplying the values but in this case I would lose a possibility of reaching intermediate points. And still, what about negative values?

2) How can I check a reachability of a specified point by a RAPID code? Generally, my program crashes now when the coordinates of the demanded point are exceeding the robot's workspace limit.

hello,

1. you can use strtoval  for converting string to numbers

2. you can use CalcJointT for checking reach, if it gives an error ERR_ROBLIMIT then you know the robot cannot reach the position

i have found the error it was in the format of using StrToVal

Hello, 

i have the same problem , i have this variable 

VAR string Fx_S1:=0.784184821186377; 

i have imported from C# addin , and when i use the command 

VAR strtoval Fx_S1; 

it gives me the following error :

 IRB4400_60kg_1.96m_245/RAPID/T_ROB1/MainModule(3,2): Name error(49): Variable name x_S1 ambiguous. 10/14/2013 8:40:28 PM General

Checked: IRB4400_60kg_1.96m_245/RAPID/T_ROB1: 1 semantic errors. 10/14/2013 8:40:28 PM RAPID

any help is really appreciated
