Parker ACR9000 Ethernet
Review the following information for setting up and configuring the Parker ACR9000 Ethernet driver. The driver communicates with Parker ACR9000 motion controllers over TCP using the ACR interactive command interpreter (AcroBASIC).
Note: This driver is experimental. Some features might not work as expected.

To set up and configure this device in Litmus Edge (LE), do the following:
- Step 1: Set up and configure the PLC device
- Step 2: Set up the PLC device in Litmus Edge DeviceHub
- Step 3: Configure the list of registers
Step 1: Set up and configure the PLC device
If the device is configured for Ethernet access, find its network parameters. Otherwise, follow the steps below.
To configure your device:
- Note down the following information and refer to it when needed.
- Device: Parker ACR9000 Ethernet
- Communication I/F: Ethernet. Refer to the following figure.
- Launch the ACR View V6.4.2.1014 software and create a project for your device model.
- Click the device in the Navigation pane, set up the device IP address, and then click Connect.
Step 2: Set up the PLC device in Litmus Edge DeviceHub
Configure the following parameters when you Connect a DeviceConnect a Device with this driver. Update default values to the specific setup of your device.
Parameter | Value |
|---|---|
Type | Parker |
Driver | Parker ACR9000 Ethernet |
NetworkAddress | The IP address of the device you defined in Step 1. Default value 192.168.0.1 |
NetworkPort | The TCP port of the device. Enter a value from 0 to 65535. Default value 5006 |
The following parameters are under Advanced Parameters.
Parameter | Value |
|---|---|
KeepAlive | The TCP keep-alive interval, in seconds. Enter a value from 0 to 7200. Enter 0 to disable keep-alive. Default value 5 |
ReadTimeout | How long the driver waits for a response, in milliseconds. Enter a value from 10 to 10000. Default value 3000 |
RetryCount | The number of times the driver retries a failed request. Enter a value from 0 to 5. Default value 0 |
PauseBetweenRetries | The pause between retries, in milliseconds. Enter a value from 0 to 2000. Default value 0 |
For the Meta Data, Status Register, and Optional Settings options, see Connect a DeviceConnect a Device.
Step 3: Configure the list of registers
When you Add a TagAdd a Tag to the connected device, see the following register table and tag parameters. This driver does not support browsing tags.

Register table
For P, the address is the parameter number. For P_Bit, the address is the parameter number followed by a two-digit bit number, from 00 to 31. For example, P_Bit address 1205 is bit 5 of parameter P12.
Name | Value Types | Access Type | Address Format | Min Address | Max Address | Description |
|---|---|---|---|---|---|---|
P | int32, float32 | R/W | DDDDD | 0 | 99999 | Parameter |
P_Bit | bit | R/W | DDDDDDD | 0 | 9999931 | Parameter bit |
Tag parameters
- Name: Select a register name from the drop-down list. The available options depend on the names in the register table.
- Value Type: Select a data type from the drop-down list. The available options depend on the register name selected.
- Address: Enter the register address in decimal format, within the min and max range in the register table. Omit leading zeros. For P_Bit, add the two-digit bit number at the end.
- PollingInterval: Enter how often the tag polls for data, in seconds. Enter 0 to disable polling. Default value 1
- Tag Name: Enter a name for the tag.
- Description (Optional): Enter a description for the tag.
- Tag Formula: Enter a formula for the tag to process the generated data. You can use two variables: value (current tag value) and timestamp (current tag UNIX time in milliseconds). The following math functions are available:
- sin
- cos
- sqrt
- tan
- power: power(x) performs the operation 10^x.
- log: log(x) is the natural logarithm (the logarithm is in base e).
- exp: exp(x) performs the operation e^x.
- Only Publish on Change of Value: Select the checkbox to publish NATS messages only when the value parameter changes. Change of Value only applies to boolean, numeric (such as int or float), and simple string data types. It does not apply to complex types, such as JSON or array. Poll-once topics are not affected by Change of Value settings, and still receive a single message.
- Meta Data: Define key-value pairs to add to the device output payload.
Note: If you use special characters in metadata key names, the special characters are replaced with underscore characters in the payload. This can cause two key names to be combined into one. For example, configuring the key names a**b and a&&b creates only one key name (a__b).
