Ccn-CcnObject
Figure 7. CcnObject or point’s properties
To access these properties, expand , expand the Boolean point and double-click Proxy Ext.
| Property | Value | Description |
|---|---|---|
| Field Name | text | Defines this point’s name (8 ASCIIcharacters).
Fid IO_Points Tables have up to 64 points. To modify each point name, change it from the Property Sheet and invoke the Fetch action. |
| Point Data Type | read-only | Configures the point’s data type (00 – 33H). |
| Data Type Enum | read-only | Configures a point’s data type enumeration.
|
| Display Type | read-only | Configures the type of display for each point from the device.
The database stores all device data values in imperial. The driver does not use this property, but instead uses the global
property on the CcnNetwork Config tab named |
| Display Digits | read-only | Configures the point’s display digit requirements. The upper nibble is the number of digits to the left of the decimal, and
the lower nibble is the number of digits to the right of the decimal.
For dataType 0 (eightBitFlags), the upper nibble specifies the number of usable bits in the byte (right to left). The driver displays this value in decimal and must be converted to hexadecimal to be interpreted (for instance a 97 decimal is a 61 hex). Thus, up to six digits display to the left of the decimal and one digit to the right. |
| Field Byte Count | read-only | Reports the point’s byte count in the table value block. |
| Discrete Text Offset | read-only | Reports the point’s discrete text offset if its discrete flag is set. |
| Config Flags | read-only | Reports the point’s config flags. Valid values are:
bit 0 – this point has a low limit bit 1 – this point has a high limit bit 7 – this point is a discrete point The driver displays this value in decimal, which must be converted to hexadecimal to be interpreted. For instance, a 128 decimal is an 80 hex and, thus, is a discrete point that does not have a low or high limit. Another common value, a 125 decimal is an 83 hex and, thus, is a discrete point that does have a low and high limit. |
| Units | read-only | Reports the point’s value in integer units. |
| Units Enum | read-only | Reports the point’s enumeration value in integer units. |
| Value Block | read-only | Reports the point’s value block assignment. |
| Value Block Offset | read-only | Reports the point’s value block offset assignment. |
| Lo Limit | read-only | Reports the point’s lo limit value. |
| Lo Limit | read-only | Reports the point’s lo limit block assignment. |
| Lo Limit Block Offset | read-only | Reports the point’s lo limit block offset assignment. |
| Hi Limit | read-only | Reports the point’s hi limit value. |
| Hi Limit Block | read-only | Reports the point’s hi limit block assignment. |
| Hi Limit Block Offset | read-only | Reports the point’s hi limit block offset assignment. |
| Variable No | read-only | Reports the point’s variable number (only applies to points under 11H, 12H, and 501H tables). |
| Description | read-only | Reports the point’s 24-character description. |
| Forceable Flag | read-only | Reports the point’s flags that can be forced.
This value is This value is Force and Auto commands can set this value to This value is The Set command can write a Ccn Output value with a Forceable Flag set to |
| Device Type | number | Assigns a numeric value to represent the device.
NOTE: This property is not used. It is meant for the FID device.
|
| Ctrl Sens Type | number | Assigns a numeric value.
NOTE: This property is not used. It is meant for the FID device.
