3.2 Processing Time of Communication Data
The following explains the processing time of the welding power source concerning the changeof I/O data in Fieldbus communication.
When an external device changes a single function by the I/O data, it takes approximately 20
ms until the change is reflected to the welding power source after the data reception is completed
in the welding power source. When changes are made to two or more functions, it takes
approximately 50 ms at maximum until all changes are reflected. (*1, *2）
When the welding power source sends I/O data, the status of the welding power source at thetime before [Communication cycle waiting time (*3)]+approx. 20 ms against the sending starttiming is reflected to the data. (*1)
*1
*2
*3

Delay may increase temporarily according to the CPU loaded conditions of the welding
power source.
When hardware operation is conducted by "Welding startup" and "Gas discharge", etc. ,additional delay will occur by the time the hardware starts working.
For instance, 0-10 ms communication cycle waiting time will occur when thecommunication interval of the I/O data is set to 10 ms.

P. 5/17

4. Application Specifications
This describes the functions allocated for the sending and receiving of I/O data using Fieldbus
communication.
The following is a description of the OUT data sent from external devices (master side) to thewelding machine (slave side), and the IN data sent from the welding machine (slave side) toexternal devices (master side).
"*TA" is put to the functions available only for WB-T500P/A350P/A500P, "*A" is put to thefunctions available only for WB-A350P/A500P, "*F" is put to the functions available only for

Perform a gas check.

Setting offset 0 / bit 3 to “1” starts gas purge.
Setting offset 0 / bit 3 to “0” stops gas purge.

Perform inching feeding of wire.

Setting offset 0 / bit 1 to “1” starts inching.
Setting offset 0 / bit 1 to “0” stops inching.

Perform welding.

Setting offset 0 / bit 0 to “1” starts welding.
Setting offset 0 / bit 0 to “0” stops welding.

Stop operation

Setting offset 0 / bit 7 to “1” stops operation.
Setting offset 0 / bit 7 to “0” releases the operation stop.

The following operations can be changed only when the setting change from an external device
is permitted. Setting change is permitted by setting offset 3 / bit 7 to “1” and prohibited by
setting offset 3 / bit 7 to “0”.
Set the welding method.

When setting the welding method to "DC TIG", set offset
4/bit 2-4 to "0".

Set the pulse control.

When setting the pulse control to "valid", set offset 5/bit 0 to
"1".

Set the welding current.

When setting the welding current to "150A", set offset 9-10
to "1500(=0x05DC)".
(offset 9: 0xDC, offset 10: 0x05)

Set the pulse peakcurrent.

When setting the pulse peak current to "350A", set offset
13-14 to "3500(=0x0DAC)".
(offset 13: 0xAC, offset 14: 0x0D)

Operation stop/
reset error

When 1, the welding power source stops operating, and theerror code is reset with E-000. When 1 is returned to 0, errors andwarnings are cleared, and the welding power source resumes
operation. However, as shown in appendix 1, welding powersource system errors and control power errors cannot be reset. In
such cases, the power to the welding power source must be shut off
and then restored.

2-

Welding condition
memory no.

Set when using the memory function of welding conditions(refer to the Owner's Manual, 6.5 "Memory Function of Welding
Conditions"). When this function will not be used, set the value to0.
Setting a welding condition memory number 1 through 100 will
set that number's corresponding saved welding condition to IN
data offset 4-29 (the saved welding condition can be checked, but
this operation by itself does not load the saved welding condition).
Setting the welding condition memory number to 0 will returnoffset 4-29 of the IN data to the currently enabled setting.

Used as the watchdog signal. This bit must alternate writing
between 0 and 1 every 0.5 seconds. When the watchdog signal is
not operating, data other than for stopping operation will not be
accepted.
If this bit does not change for more than 1 second, the welding
machine will have an error stop. However, if the watchdog signal
is not operating when the welding machine is started or recovers
from an error stop, the welding machine will output a warning,
and the error stop will not re-occur. The warning will be canceledwhen the watchdog signal begins operating.
Operates as drainage being ON when 1 is set.

Setting the welding condition memory load to 1 will load thewelding condition of the number set to the welding condition
memory number.
However, note that if the setting change permission of offset
3/bit 7 is set to 1, immediately after the welding condition isloaded, the setting values for offset 4 and greater will be applied
as the currently enabled settings. When using to load welding
condition memory, normally set the setting change permission to0.
When both welding condition memory load and welding
condition memory write are set to 1, both operations are disabled.

Setting change
permission

When this bit is 1, the setting values of offset 4 and greater are
applied to the welding machine. When this bit is 0, the setting
values of offset 4 and greater are ignored by the welding machine.
However, function numbers of offsets 18, 21, 24, and 27 are notparameters that are changes for the welding machine, and so they
are always recognized. For example, when the setting change
permission is 0, and offset 18 (function (port 1) no.) is set, thevalues of offsets 19 and 20 (function (port 1) setting value) will not
be applied to the welding machine, but the function values alreadyset to the welding machine will be output to the IN data offsets 19
