Table 1. DP MASTER DIGITAL I/O CONFIG SCREEN ITEMS
ITEM | DESCRIPTION |
---|---|
Adr | The slave station address. |
IN-BYTE | This data is the number of data bye |
OUT-BYTE | This data is the number of data bytes output to the slave. |
IN-OFS | This data is the offset in bytes from the beginning of the master input data area (DI data area). The number of input data area (DI data area) bytes is set to the value obtained by INPUT BYTES on DP MASTER SETUP Screen. |
OUT-OFS | This data is the offset in bytes from the beginning of the master output data area (DO data area). The number of output data area (DO data area) bytes is set to the value obtained by OUTPUT BYTES on DP MASTER SETUP Screen. |
Procedure 1. Displaying the DP MASTER DIGITAL I/O CONFIG Screen
Press MENU.
Select I/O.
Press F1, [TYPE].
Select PROFIBUS.
If the DP MASTER DIGITAL I/O CONFIG screen is not displayed, press F3, [OTHER], and select DIGITAL I/O. If F3, [OTHER], is not displayed, press NEXT, >. You can see the following screen.

To change the setting, set the cursor to the item to be set, and enter a value by using the numeric keys.
To clear the I/O assignment,
Press NEXT,>.
Press F1,CLR_ASG, then the following message is displayed. "Clear all assignments ?"
Press F4,YES to clear all I/O assignment.
To save all the PROFIBUS-DP setup data to a file,
Press FCTN.
Select SAVE. This will save all the PROFIBUS-DP setup data to the file, PROFIBUS.SV file, on the default device.
Table 2. DP MASTER ANALOG I/O CONFIG SCREEN (1)
ITEM | DESCRIPTION |
---|---|
Number of Device | This data specifies how many slave devices (referred to as analog devices) are involved in the transmission of a set of arc welding input/output signals, the arc welding stick detection signal, and arc welding or sealing analog signals (together referred to as analog input/output data) via the PROFIBUS-DP interface. In other words, it specifies the number of arc welding or sealing equipments that can be connected to the controller over a PROFIBUS-DP network. A maximum of three equipments can be connected. After changing this data, clear the I/O assignment data, and switch the power off then on again. |
Arc Weld Signal | This data specifies whether arc welding input/output and arc welding stick detection signals are to be output. If DISABLE (default), the arc welding signals are not transmitted. Instead, only analog data is transmitted. If ENABLE, the arc welding signals are transmitted. After changing this data, clear the I/O assignment data, and switch the power off then on again. |
Table 3. DP MASTER ANALOG I/O CONFIG SCREEN (2)
ITEM | DESCRIPTION |
---|---|
AI SLAVE ADDRESS | This data specifies the slave address for an analog input device.* |
AO SLAVE ADDRESS | This data specifies the slave address for an analog output device.* |
NUMBER OF AI | This data specifies the number of analog input channels.** |
NUMBER OF AO | This data specifies the number of analog output channels.** |
AI START BIT | An analog input consists of one word per channel. This data specifies the first bit in the word data to become effective. |
AO START BIT | An analog output consists of one word per channel. This data specifies the first bit in the word data to become effective. |
AI VALID/NOVALID BITS | This data specifies the number of valid/no
valid bits on analog input word data. The no valid bits start from bit0. The
valid bits start after the no valid bits. If 13, 3, the valid bits are 13
and the no valid bits are 3. This setting is indicated as follows:
bit15, bit14, bit13, bit12, bit11, bit10, bit9, bit8 all are valid bits bit7, bit6, bit5, bit4, and bit3 are valid bits bit2, bit1, and bit0 are no valid bits (These bits are always 0) |
AO VALID/NOVALID BITS | This data specifies the number of valid/no valid bits on a analog output word data. The representation of this data is the same as AI VALID / NOVALID BITS. |
AI OFFSET ADDRESS | This data specifies the first effective analog input data byte in an area dedicated to data received from a unit having the slave address specified in AI SLAVE ADDRESS. |
AO OFFSET ADDRESS | This data specifies the first effective analog output data byte in an area dedicated to data received from a unit having the slave address specified in AO SLAVE ADDRESS. |
*For an analog device having both analog input and output functions, both of the above data must be set to the same value. For an input-only analog device, set AO SLAVE ADDRESS to 0. For an output-only analog device, set AI SLAVE ADDRESS to 0.
**Analog data is represented as a two's complement. Both of the above data are default settings to two channels. They can, however, be set up to 6 channels. An attempt to specify more than six channels will result in only six channels being specified. After changing these data, clear the I/O assignment data, and switch the power off then on again.
Word = 2 bytes.
