| Field Name | Description |
|---|---|
| type | Specifies the protocol type. Currently two types are
supported:
0 = Standard 1 = Extended |
| bit | This specifies the "bit" to set/clear from the table value. The least significant "bit" is zero, while the most significant bit is fifteen. This will cause the scan task to first read the table value from the PLC and then set/clear this bit before writing it back to the PLC. This value must be set to minus one if the whole table value is to be used. Note that there is the potential for the value in the PLC to change before the value is written to it. |
| element count | This field specifies the number of elements for the write. |
| table number | This field specifies the data table number. |
| data | This field specifies the upper case ASCII character that represents the table letter. |
