In addition to the standard properties (Status, Enabled, Fault Cause, Health, Alarm Source Info, Monitor, Tuning Policies and Poll Scheduler), these properties configure this component:
| Property | Value | Description |
|---|---|---|
| Retry Count | number | Configures how many times to repeat a network read request, if no response is received before the response timeout interval elapses. |
| Response Timeout | hours minutes seconds (defaults to .500 seconds) | Configures the length of time before the system times out when interrogating a device on the network. Start by setting this
value to a large number, such as 40 seconds. Then, reduce it depending on the number of devices and on the discovery performance.
NOTE: Baud rate also impacts performance especially if each device has a different baud rate.
|
| Port Name | COM2, COM3 | Defines the communication port to use: none, COM2 or COM3.
|
| Trunk | number | Specifies which trunk the port is connected to.
Each RS-485 connection is called a trunk. If your network has multiple RS-485 trunks, a separate network and remote I/O module are required to support each. |
| Baud Rate | read-only | Defines communication speed in bits per second. |
| Sdi Value Config | additional properties | Sdi (Sensor Digital Interface) configures input from the sensor.
Refer to Sdi Value Config. |
| Push To Points | true (default) or false |
Enables (true) and disables (false) the sending of data to points.
|
| Output Failsafe Config | read-only seconds (defaults to 8) | Configures timeout values. Refer to Output Failsafe Config. |
| Unsolicited Msg Count | read-only | Reports the number of unexpected messages. |
| Unsolicited Process Time | read-only | Reports the amount of unexpected process time. |
| Unsolicited Message Rate | read-only | Reports the rate at which unexpected messages are being received. |
| Pushed Unsolicited Message Rate | read-only | Reports the rate at which unexpected messages are being sent. |
| Keypad Entry Time | hours minutes seconds (defaults to 10 seconds) | Configures an amount of time. |
| Show Results Time | hours minutes seconds (defaults to 2 seconds) | Configures an amount of time. |
| Validation Timeout | hours minutes seconds (defaults to 10 seconds) | Configures an amount of time. |
| Base Board Avail Version | read-only | Reports a version number. |
| Remote Reader Avail Version | read-only | Reports a version number. |
| Remote Io Avail Version | read-only | Reports a version number. |
| Network version | read-only | Reports a version number. |
Sdi Value Config
Figure 76. Sdi Value Config properties
| Property | Value | Description |
|---|---|---|
| Cut Value | number (defaults to 3412) | Defines a value for the cut voltage parameter on the network. |
| Open Value | number (defaults to 2047) | Defines a value for the open voltage parameter on the network. |
| Closed Value | number (defaults to 682) | Defines a value for the close voltage parameter on the network. |
Output Failsafe Config
Figure 77. Output Failsafe Config properties
| Property | Value | Description |
|---|---|---|
| Comm Loss TImeout | seconds (defaults to 8 seconds) | Defines a number of seconds after which the station stops sending data, thereby indicating a loss of communication signal. |
| Startup Timeout | seconds (defaults to 180 seconds) | Defines a number of seconds after which the startup times out. |
