Litmus Edge Compatible Series

Compatibility parameter	Compatible items
Driver type	Ethernet
Validated devices/series	Vipa 300s PLC series

To set up and configure this device in Litmus Edge, you will need to 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: VIPA CPU 315-4NE12

Communication I/F: Ethernet. Refer to the following figure.

Reference image of device

Launch Primary Setting Tool and set up Set PG/PC interface to use the network adapter.

Browse the devices in the subnet and set up the network parameters for the device, and then download into the device.

Launch SIMATIC Manager and configure HW Config.

From the project, select CPU318-2 DP as the CPU module with two CP 343-1 modules.

In NetPro, set up Set PG/PC Interface and use the adapter in the same subnet with the device.

Double-click the module icon and set up the network parameters.

Download the setting into the device.

Open the OB1 block and make connection with the device.

Step 2: Set up the PLC Device in Litmus Edge DeviceHub

Configure the following parameters when you Connect a Device with this driver. Update default values to the specific setup of your device.

Parameter	Value
Type	Vipa
Driver	Vipa 300s Ethernet
Network Address	The device address you defined in Step 1
Port	102
Slot Number	1

Step 3: Configure the List of Registers

When you Add a Tag to the connected device, refer to the following register table and tag parameters.

See the following additional resources if necessary:

Organize Device and Tag Data by Using Metadata

Tag Formula Variables

Register Table

Name	Value Type	Address Format	Max Address
I	bit, byte, char, word, int, dword, dint, real, string	DDDDd	40957
Q	bit, byte, char, word, int, dword, dint, real, string	DDDDd	40957
M	bit, byte, char, word, int, dword, dint, real, string	DDDDd	40957
DB	bit, byte, char, word, int, dword, dint, real, string	DDDDDd	327677

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.

Polling Interval: Enter a value in seconds. This determines how often the tag should poll the register for data.

Tag Name: Enter a name for the tag.

Description (Optional): Enter a description for the tag.

Address: Enter a tag address. The value must in the decimal format, within the allowed min/max range. Omit the leading zeros. The device might use the decimal (D), hexadecimal (H), or octal (O) address format. See the Register Table at the bottom of the dialog box. For Bit tags, append the bit address without the bit separator. The lowercase letters in the address format indicate how many digits you should enter in the Bit address.

DB Number: Enter the data block number of the tag.

Count: Enter the number of register values to read. A count higher than 1 will generate an array of values from the address value configured and respective subsequent address values.

Tag Formula: Enter a formula for the tag to process the generated data. Two variables are permitted: value (current tag value) and timestamp (current tag UNIX time in milliseconds). The following math functions are available:

sqrt

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 customize NATS messages to be published only when the value parameter changes from a previous value to a new one. 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 will not be affected by Change of Value settings. These topics will still only see a single message.

Meta Data: Metadata summarizes basic information about data. This feature allows you to define key-value pair data for the device output payload later on. It can then be used to find, use, and reuse particular instances of data.

Note: If you use special characters in meta data 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 will cause only one key name to be created (a__b).
