6.8 Service and Programming Aids

6.8.1 CAN-Assist, Art. no. 502 800-880

PC based tool that in Passive Mode allows listening to the CAN-bus traffic in the

Weld system during the current process.

In Master Mode, with the connection to the robot master disconnected, the I/O-

function in the different units in the system can be activated, parameters loaded or

changed.

CAN-Assist is supplied as a package with hardware and a CD containing software

and documentation.

6.9 Diagnostics – Error Handling

The PIB is fitted with two light-emitting diodes according to the DeviceNet speci-

fication, see Figure 19 on page 35.

One of the diodes has the designation NS (Network Status) and indicates the func-

tion of the CAN bus. The other one has the designation MS (Module Status) and

indicates the PIB function.

Correct function is indicated by a green light coming on and incorrect function by a

red light. During the initiation phase, which can take a few seconds, the light of the

diodes changes.

Exception: On ARCITEC LRA/S4C (jumper TB9 made) does not indicate NS

while MS indicates the status as set out above.

During software execution on the robot (start, stop and current execution) the con-

tinuous transfer from PIB of the function status from the PIB as well as from the

weld process takes place via the sensors connected to the PIB.

In the event of an error on PIB an error message is given to the robot programming

unit as a warning to call action, see the table below. The weld process is not inter-

rupted.

If the error concerns process supervision (shield gas, weld current) the weld proc-

ess is interrupted with the error message "Arc Supervision".

Error messages are acknowledged by pressing OK.

When the error is corrected a message appears to confirm the this. If a two errors

occur at the same time and the first error is not corrected this is shown during the

next restart. If the second error is corrected the previous error returns during the

next start. If both errors are eliminated at the same time only the last one is con-

firmed.
