Belden Horizon Data Operations Compatible Series

Compatibility parameter	Compatible items
Driver type	Ethernet
Validated devices/series	Any PLC model that supports FANUC FOCAS

To set up and configure this device in Belden Horizon Data Operations, you will need to do the following:

Step 1: Set up and Configure the PLC Device
Step 2: Set up the PLC Device in Belden Horizon Data Operations 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.

Review the following parameters for the PLC Configuration.

Supported Data Types

Refer to the following supported data types by Fanuc and Belden Horizon Data Operations. Below is for the Fanuc PMC (Programmable Machine Control).

Fanuc Macro variables support the FLOAT data type.

Table 1

Data Type	Size
BYTE	1 byte
WORD	2 bytes

Table 2

Signed Value	Data Type	Size
INT8	SINT	1 byte
INT16	INT	2 bytes
INT32	DINT	4 bytes

Table 3

Unsigned Value	Data Type	Size
UINT8	USINT	1 byte
UINT16	UINT	2 bytes
UINT32	UDINT	4 bytes

The Fanuc PMC System is the interface between the Fanuc CNC and the machine tool. For information on the PMC system, visit the Fanuc Corporation website.

RDPMC Tags

RDPMC tags provide all information about the Address Type, the Address Number to read data from, and Size within the tag itself.

Address types

Example of an RDPMC Tag

Tag	Address Type	Address Number	Size
Rdpmc [9_746_2]	D	746	4 bytes

In the previous example, 9 refers to an address type listed in the image, 746 is the address number to read data from, and 2 means that the data is four bytes long.

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. 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.
Path No: Enter the path number.
- If you are using 2-path control with independent macros on each path, then entering 1 or 2 should be the correct configuration.
- If you are using custom macro common variables (the macros used are the same for each path), then this value should be irrelevant and the default value of 1 can be used.
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:
- sin
- cos
- sqrt
- tan
- power
- log
- exp
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.
