Error compiling for board Arduino/Genuino Uno.

This report would have more information with

Define it in your code which module is used ENC28J60 or wiznet module. Read user guide and make necessary changes in the code.

I did defining module which i'm using was ENC28J60. but the example program given is giving the same compilation error

pls give some suggestion if anything wrong i'm using arduino compiler.

Hi santhosh1211,
In "ModbusTCP.h" file, you should comment out 3 lines below by ' // ':
#ifndef WIZNET_W5100
#ifndef ENC28J60
#ifndef ESP8266

You will solve the problem.
