The Points tab is structured as a table and is the primary user interface for the VGE tool.
Green columns indicate Metasys system parameters and blue columns indicate Modbus protocol parameters.
|Vendor Configuration Data (VCD)
|VCD is the reference used inside of a Metasys object.
|General Parameters (Green Header)
|This point object class can be AI, AO, BI, BO, MI, or MO. Depending on the object type selected, the other columns are activated.
|Unique ID 1
|The unique identifier of the object in Metasys. The maximum length of this field is 32 characters and it cannot contain special characters.
|The description of the object in Metasys. The maximum length of this field is 40 characters.
|The engineering units for the analog objects (AI and AO). This value can be selected from the list of available units into Metasys.
|The text used for the binary (BI and BO) and multi-state (MI and MO) objects. This value can be selected from the list of available states text into Metasys.
|The display precision for analog objects (AI and AO). This value can be selected from the list of available display precision in Metasys.
|Modbus Parameters (Blue Header)
Modbus function related to the point. This value can be:
Additional “dummy” function codes for internal use are available:
|The Modbus address of the Register. This value is zero-based.
|The complete Modbus reference in the Modicon format. This value is one-based. This field is read-only and calculated from the Function and Address fields.
|A format that must be applied to the data coming from Modbus. Example: SIGN16 means value express on 16 bits with sign (from -32768 to 32767).
A formula that must be applied to the value coming from Modbus. For some formulas, Slope (m) and Intercept (q) fields are required.
|The multiplication or division factor (according to the formula used) applied to the value coming from Modbus.
|The offset value (according to the formula used) applied to the value coming from Modbus.
|The list of values that convert the value coming from the field into the value that is available into the NIEx9 user's interface. It is typically used to convert an integer into Metasys Multi-state (MI, MO) or Binary (BI, BO).
|Miscellaneous (Orange Header)
|Used to add additional information related to the specific row.
