PAL Controller Settings

Topic: PAL006

 

When first launched, the PAL Configuration Software will open with the PAL Controller tab active. Here, the user will configure the various parameters for the PAL Controller.

 

Using the image and table below for reference, set the PAL Controller settings.

 

Setting

Description

IP Address

The IP address for the target PAL EtherNet/IP controller.

Mapping Version

At this time, the value of 4 should be fixed for this setting. In the future, the version may change and require a different value.

Fail Safe Byte

The valid options for this setting are:

  • Reset(default): In the case of communications loss, all outputs will turn off.
  • Hold Last State: In the case of communications loss, all outputs will remain in the state they were when the communications were lost.
  • Fault Mode: In the case of communications loss, all outputs will behave according to the individual setting for each solenoid valve and Output modules (see each module’s configuration settings for more information).

System Start

The options for this setting are:

  • External: Requires that the configuration settings be sent every time the unit has been powered up. This is typically accomplished by using the Configuration path with an I/O messaging connection.
  • Store Parameters(default): Allows that you only need to send the settings one time and they will be retained through power cycles. This is the recommended option when utilizing the NITRA Pneumatic Automation Configuration Tool.

Endianness
  • “Motorola”/Big Endian: The data will be transmitted high byte followed by low byte of the data.
  • “Intel”/Little Endian (default): The data will be transmitted low byte followed by high byte of the data. If you are not sure which format your device expects, try the default first and if the data doesn’t match what is expected, try the other setting.

Valves Data Refresh Time (ms)

The update time between the controller and the solenoid valves. A longer time gives the controller more time for other functions, such as updating the actuators (I/O modules). Default: 10ms.

IO Modules Data Refresh Time (ms)

The update time between the controller and the I/O modules. A longer time gives the controller more time for other functions, such as updating the solenoid valves. Default: 10ms.
