LinPAC-52xx Series XV-Board API User Manual 3

1. Introduction

This manual is intended to be used as a reference for users who need to use API functions to

communicate with XV-Boards inserted into an LP-22xx/52xx series controller via the Modbus

protocol.

1.1. What is the I/O Expansion Bus?

The LinPAC-22xx/52xx series provides an I/O expansion bus which can be used to implement

various I/O functions, such as D/I, D/O, A/I, A/O, A/D, D/A, Timer/Counter, and other I/O

functions.

However, only one XV-Board can be inserted into each PAC at a time. For more information

related to the XV-Board series, refer to:

http://www.icpdas.com/root/product/solutions/hmi_touch_monitor/touchpad/xv-board_selection.html

1.2. Demo programs

ICP DAS provides a range of demo programs that can be used to implement a variety of

functions on the LP-22xx/52xx controller. To utilize these demo programs, transfer the files to the

LP-22xx/52xx controller from the LinPAC AM335X SDK.

The demo programs can be found in either the

C:\cygwin\LinPAC_AM335x_SDK\examples\xvboard\ or the

root@LinuxPC-ICPDAS:/icpdas/linpac_am335x_sdk/i8k/examples/xvboard/ folder.

2. XV-Board API functions

The following is an overview of the API functions used by the LP-22xx/52xx series controller that

contains an XV-Board.

2.1. modbusRequest

Description:

This function is used to send a Modbus protocol request.

Syntax:

[ C ]

int modbusRequest(char cPort, char cNetID, char cFunction, WORD wAddr,

WORD wCount, char szBuf, WORD wBufLen, WORD wTimeout, WORD *wT)

Parameters:

cPort: [Input] The number of the COM port for the XV-Board. 1=COM1=/dev/ttyO1.

cNetID: [Input] The NetID for the device.

The default slave address for the XV-Board is '1'.

cFunction: [Input] The Modbus RTU protocol function code.

wAddr: [Input] The channel address.

Note: Input the channel address mapping in decimal format.

wCount: [Input] The number of channels.

szBuf[ ]: [Input/Output] Used to set or read back the value from a function code.

wBufLen: [Input] The length of the szBuf[ ].

wTimeout: [Input] The Timeout setting. The normal value is 100 milliseconds.

*wT: [Output] The total duration of the send/receive interval. Unit=1 ms.

Return Values:

0: The function was successfully processed.

Other: The processing failed.

Refer to Chapter 3: “Error Codes” for details of other returned values.

Example:

int RetValue, timeout=100, count=1, netid=1;

int comport=COM1; /* Refer to [Remark 1] */

int function=1; /* Refer to [Remark 2] */

int addr=33; /* Refer to [Remark 3] */

char szBuf[80];

DWORD baudrate=115200;

WORD wT;

/* Open the device file */

RetValue=Open_Com(comport, baudrate, Data8Bit, NonParity, OneStopBit);

if (RetValue > 0) {

printf("open COM%d failed!\n",comport);

return FAILURE;

}

RetValue=modbusRequest(comport, netid, function, addr, count, szBuf, sizeof(szBuf),

timeout, &wT);

Close_Com(comport);

if (RetValue==0) {

if((function==1)||(function==2))

printf("%d", szBuf[0]);

else {

RetValue=(szBuf[0]<<8)|szBuf[1];

printf("%ld", RetValue);

}

Remarks:

[1] Refer to the communication port number in the table below when sending the Modbus

protocol request.

'cPort’ parameter for the XV-Board module: 1=COM1=/dev/ttyO1.

'cPort' parameter for the RS-485 serial port: 2=COM2=/dev/ttyO2, 5=COM5=/dev/ttyO5.

Note: Remote I/O modules can be remotely controlled through an RS-485 serial bus. Refer

to Chapter 4.1.2: “DIO” for details of demonstration details.
