Configuration via Strings |
This Driver allows configuring Tags via Strings, using the same formats used on OPC Drivers. Configuring via Strings is performed using the Device and Item properties of Elipse E3, Elipse Power, or Elipse Water Tags.
NOTE |
Configuring via Strings was not available for Elipse SCADA by the time this version was released. |
The Device property can be used to define a PLC address, using the <net>.plc: format, in which net is an optional parameter specifying a network number, and plc specifies a PLC address. If the Device property is left empty, the address must be informed in the Item property using the same format, followed by a colon. If the network address is not present, consider it as 0 (zero). If the address is defined in the Device property, then the final colon can be dismissed. The Item property defines operand's data to access. The next table contains mnemonics that can be used by this Driver.

In which:
•Bold characters represent fixed mnemonics identifying commands, while regular characters represent values that must be replaced
•The y character represents the initial position on a table
•The b character represents a bit number, ranging from 0 (zero, the least significant bit) to 31 (the most significant bit), but the actual maximum number depends on the number of bits on a data type
The next table presents usage examples of mnemonics and their respective conversion into N or B parameters, according to the internal conversion performed by this Driver.

NOTE |
E and S mnemonics are both mapped to PLC Tags with the N2 parameter equal to 6 (six). The difference is only on the operation itself, because only readings in E operands and writings in S operands are allowed. |
