When the Gateway Communication Driver receives data from a DDE/SuiteLink source and sends it to an OPC client, it converts DDE/SuiteLink types to OPC types as follows:
|
DDE/SuiteLink Type |
OPC Variant Canonical Mapping |
|
Discrete |
VT_BOOL |
|
Float |
VT_R4 |
|
Integer |
VT_I4 |
|
String |
VT_BSTR |
Note: In case of conversion failures, Gateway Communication Driver returns Bad quality to the OPC client.
