EMBEDDED ETHERNET PORT AND PCMCIA ETHERNET

CARD

The embedded Ethernet function can be used by selecting one of two types of devices: the embedded

Ethernet port and PCMCIA Ethernet card.

A selection can also be made to stop the embedded Ethernet function.

The PCMCIA Ethernet card is to be inserted into the memory card slot for temporary communication.

CAUTION

1 When using the embedded Ethernet function for the first time, set an IP address

and other items carefully as instructed by the network administrator, then

perform a sufficient communication test.

Note that an incorrect IP address or other setting may cause a communication

failure on the entire network.

2 A unit such as a PC situated in the same network can increase the

communication processing load on the CNC even if the unit is not

communicating with the CNC.

Avoid connecting the CNC to a factory-wide network. Use a router or the like to

separate the network including the CNC from the other networks.

NOTE

1 The embedded Ethernet port of Series 32i is available as an option.

2 Use the PCMCIA Ethernet card designated by FANUC. General Ethernet cards

available on the market cannot be used.

3 The PCMCIA Ethernet card is used for FANUC LADDER-III or SERVO GUIDE.

4 Use the PCMCIA Ethernet card just for temporary communication as described

above. Avoid using the card for continuous communication.

5 The PCMCIA Ethernet card is inserted into a memory card slot, with a part of the

card left uninserted. When using the PCMCIA Ethernet card, take great care not

to damage the card by hitting the protruding part of the card.

When the card becomes unnecessary, remove the card immediately, in order to

prevent any damage to the card.

Setting of the Unsolicited Messaging Function

This subsection describes the setting required to operate the unsolicited messaging function with the

embedded Ethernet function.

NOTE

To use the unsolicited messaging function with the embedded Ethernet port, the

enhanced embedded Ethernet function (-R952) is required.

7.2.4.1 Overview

This subsection provides an overview of the unsolicited messaging function and describes the execution

procedure.

Overview of the unsolicited messaging function

An overview of the unsolicited messaging function is provided below.

With the unsolicited messaging function, the CNC transmits messages (CNC/PMC data) in an unsolicited

manner to application software on the personal computer according to a command from an NC program

or ladder program. By using this function, the need for application processing on the personal computer to

periodically inquire about the state of the CNC can be eliminated.

B-64485EN/01

7.EMBEDDED ETHERNET FUNCTION

Unsolicited messaging function execution procedure

The execution procedure for the unsolicited messaging function is described below.

Preparation on the personal compute

Create an application using the FOCAS2 function for the unsolicited messaging function and install

the unsolicited message server on a personal computer. For the method of creating an application

using the FOCAS2 function for the unsolicited messaging function and the method of installing the

unsolicited message server, refer to Chapter

5, "Unsolicited Messaging Function", in the

“Data

Window Library Specifications" supplied with the FOCAS1/2 library.

Preparation on the CNC

Create an NC program or ladder program for controlling unsolicited messaging.

For the method of creating an NC program or ladder program, see Subsection 7.2.4.6, "Execution

methods".

Setting of the communication parameters for the unsolicited messaging function

To use the unsolicited messaging function, the following communication parameter settings are

needed:

(1) Setting for using the FOCAS2/Ethernet function

(2) Setting of the parameters for the unsolicited messaging function

For (2), a choice can be made from two modes of setting: CNC mode for setting on the CNC screen

and the PC mode for setting on the personal computer.

For the setting method of (1) and (2), see Subsection 7.2.4.2, "Setting of the FOCAS2/Ethernet

function" through Subsection 7.2.4.5, "Setting on the personal computer".

Starting the NC program or ladder program

Start the NC program or ladder program created in step 2, "Preparation on the CNC". At this time,

no unsolicited message is transmitted to the personal computer until step 5, "Starting the unsolicited

messaging function", is executed.

Starting the unsolicited messaging function

Execute the FOCAS2 function cnc_unsolicstart on the personal computer. This execution places the

CNC in the state (named "Ready") where a transmission request from the NC program or ladder

program is awaited. Each time a transmission request is made from the NC program or ladder

program, an unsolicited message is automatically transmitted to the personal computer.

Ending the unsolicited messaging function

To end unsolicited message transmission, execute the FOCAS2 function cnc_unsolicstop on the

personal computer. This execution places the CNC in the state (named "Not Ready") where no

unsolicited message is transmitted even when a request for transmission is made from the NC

program or ladder program.

7.2.4.2 Setting of the FOCAS2/Ethernet function

This subsection describes the setting of the FOCAS2/Ethernet function for operating the unsolicited

messaging function.

Procedure

Enable the unsolicited messaging function according to "Related NC parameters" described later.

<path-number>:<PMC-address>

When specifying the PMC address R0500 of the second PMC path, for

example, input "2:R500". When only the PMC address (R500) is input, the

specification of the first path (1:R0500) is assumed for processing.

When the key for ":" is unavailable, use the key for "/" or "EOB" instead.

(2) Ensure that a PMC address area for control never overlaps PMC areas used

by other functions (FL-net, PROFIBUS-DP, DeviceNet, and CC-Link).

When setting a macro variable for control or a macro variable for transmission,

observe the following:

(1) When a multi-path CNC is used, use the following input format:

<path-number>:<variable-number>

When specifying variable number #100 of the second CNC path, for

• cnc_unsolicstart

Start of unsolicited messaging

For details, refer to Chapter

5, "Unsolicited Messaging Function", in the

“Data Window Library

Specifications" supplied with the FOCAS1/2 library.

NOTE

1 To start unsolicited messaging, the FOCAS2 function cnc_wrunsolicprm2 needs

to be executed first then the FOCAS2 function cnc_unsolicstart needs to be

executed.

2 The FOCAS2 function cnc_wrunsolicprm2 can be executed only in the "Not

Ready" state. For details of the state, see "Display items" in Subsection 7.2.4.3,

"Mode selection".

3 When the FOCAS2 function cnc_wrunsolicprm2 is executed, the Unsolicited

Message screen (CONNECT) displays the settings made on the personal

computer.

7.2.4.6 Execution methods

How to execute the unsolicited messaging function is described below.

To execute the unsolicited messaging function, three methods are available:

• Using a PMC address for control based on the response notification method in a ladder program

• Using a PMC address for control based on the simplified method in a ladder program

• Using a macro variable for control based on the simplified method in an NC program

- 457 -

7.EMBEDDED ETHERNET FUNCTION

B-64485EN/01

NOTE

1 When a ladder program is used, the response notification method and the

simplified method are available. A major difference is that the response

notification method sends RES_CODE to the ladder program in response to data

transmission but the simplified method does not send a response.

To utilize a ladder program based on logic used with the Series 16i, for example,

use the response notification method. When RES_CODE is unnecessary or a

new ladder program is created, the simplified method can be used.

2 RES_CODE is recorded on the Ethernet log screen when a value other than

0x00 and 0x01 is detected.

3 For details of RES_CODE, refer to Chapter 5, "Unsolicited Messaging Function", in the

“Data Window Library Specifications" supplied with the FOCAS1/2 library.

When a PMC address for control is used (response notification method)

A description of using a PMC address for control in a ladder program according to the response

notification method is provided below.

NOTE

A combination of a PMC address for control and a macro variable for

transmission is also usable. In this case, note that the read timing of the value of

a macro variable to be transmitted cannot be identified when viewed from the

ladder program.

In the description below, a PMC address is used for both of control and

transmission.

Explanation of PMC address signals for control

A detailed description of PMC address signals for control used to execute the unsolicited messaging

function is provided below. A PMC address area for control consists of 2 bytes.

A description of using a macro variable for control in an NC program according to the simplified method

is provided below.

Macro variables for control are classified as custom macros and RTM macros, but the same execution

method is applicable.

NOTE

A combination of a macro variable for control and a PMC address for

transmission is also usable. In this case, note that the read timing of the value of

PMC data to be transmitted cannot be identified when viewed from the NC

program.

In the description below, a macro variable is used for both of control and

transmission.

Explanation of a macro variable for control

A detailed description of a macro variable for control used to execute the unsolicited messaging function

is provided below. One macro variable for control is used.

The description below assumes that #xxxx (with no CNC path number specified) is used as a macro

variable number for control.

REQ <#xxxx>

[Name] Message transmission request signal

[Classification] Input/Output signal

[Function] Requests transmission of an unsolicited message.

[Operation] After preparing a transmission message in a macro variable for transmission, the NC

program sets this signal to 1. The message is then transmitted to the personal computer.

Upon reception of a response to the message, the CNC (communication function) clears

this signal to 0.

NOTE

A REQ input/output value is a real number. So, "0" means "0.0", and "1" means

"1.0".

Timing chart of a macro variable for control

The timing chart of a macro variable for control based on the simplified method is described below.
