ReqDiagnostics GVL
The "ReqDiagnostics" GVL declares the diagnostic variables of the MODBUS Master/Client and
DNP3 Client requests. It is not mandatory, but it is recommended to use the automatic generation of
these variables, which is done by clicking on the button "Generate Diagnostic Variables" in the
device requisitions tab. The declaration of such variables follows the subsequent structure:
Variable declaration of request diagnostic:
[Device name]_REQDG_[Request number]: [Variable type];
Where:
Device name:
Name displayed in the TreeView for the device.
Request number:
Request number declared in the request device table, ordered from top to bottom,
starting in 0001.
Variable type:
"T_DIAG_MODBUS_RTU_MAPPING_1" for MODBUS Master,
"T_DIAG_MODBUS_ETH_MAPPING_1" for MODBUS Client and
"T_DIAG_DNP_CLIENT_REQUEST_1" for DNP3 Client.
