You should match the data type of the Plant SCADA variable tag with the data type of the mapped ControlLogix system PLC tag as per the following table:
|
ControlLogix Data Description |
Plant SCADA Address Format |
Access rights |
Plant SCADA Data Type |
|
BOOL |
<TagName>{<IndexNumber>} |
R/W |
DIGITAL |
|
SINT |
<TagName>{<IndexNumber>} |
R/W |
BYTE |
|
INT |
<TagName>{<IndexNumber>} |
R/W |
INTEGER |
|
DINT |
<TagName>{<IndexNumber>} |
R/W |
LONG |
|
REAL |
<TagName>{<IndexNumber>} |
R/W |
REAL |
|
String structure (see below) or STRING (supplied by RSLinx) |
<TagName>{<IndexNumber>} |
R/W |
STRING |
The string structure must follow the format:
{
DINT LEN
SINT[ ] DATA
}
