Table 57: 0x800F (32783) Language Selection
Size | Description |
| |
|
|
| |
|
|
| |
1 byte | Holds the currently selected language from the list in parameter 800E. |

Table 58: 0x8010 (32784) Device Semaphore |
| ||
|
|
| |
Size | Description |
| |
|
| ||
|
| ||
4 bytes | The purpose of this parameter is to provide a method for tools to access a QCPort node in a | ||
| manner. |
| |
| This parameter consists of a field of 2 UNITs organized as follows: |
| |
| Byte |
| |
| Node ID Low byte |
| |
| Node ID High byte |
| |
| Lockout Time in tenths of seconds Low byte |
| |
| Lockout Time in tenths of seconds High byte |
| |
| If the above 4 bytes are 0, anyone can write to this parameter. This parameter is cleared by the Clear Semaphore | ||
| command that can be sent by anyone. If all 4 bytes are not 0 and a write (other than a clear) to this parameter is | ||
| attempted, an error message will be returned. The parameter will be cleared when the timer counts down to 0. | ||
| If the node ID field is 0, all set parameters to the node will be accepted. If the node ID field is not 0, set parameter | ||
| commands to the node will only be accepted from the device having the same node ID as that contained in this | ||
| parameter. Note that if the node ID is set to zero at the same time that a | ||
| timer will not decrement. |

Table 59: 0x8023 (32803) Output Comm Loss Action |
| ||
|
|
| |
Size | Description |
| |
|
| ||
|
| ||
The n bytes | Used in discrete output modules. Each bit of this parameter is associated with an output bit and defines the | ||
| behavior of that output upon detection of communications loss. |
| |
| If a bit in this parameter is 1, the output bit holds the last state. |
| |
| If a bit is 0, the output bit is determined by the initial value. |

Table 60: 0x8024 (32804) Input Debounce |
| ||
|
|
| |
Size | Description |
| |
|
| ||
|
| ||
The n bytes | Used with discrete input devices. This parameter consists of a series of UNITs, two bytes for each discrete input | ||
| and holds the debounce time for that input. |
| |
|

| ||
|
|
| |
Size | Description |
| |
|
| ||
|
|
|
|
2 bytes | This parameter may be used with modules having a hardware node ID switch and represents the actual setting | ||
| of that switch. |

| ||
Size | Description |
| |
|
|
| |
|
|
| |
n Bytes | Determines the communication loss behavior of the output module. |
| |
| 0 | = Hold last state |
|
| 1 | = Use Communication Loss Value |
|
| 2 | = Use Initial Value |
