# Modbus TCP/IP slave - functions

I'm developing a slave modbus TCP/IP application on the PIC32 platform. Do you have any idea about the the role of the eMyRegInputCB (UBYTE *pubRegBuffer, USHORT usAddress, USHORT usNRegs) function or the eMyRegHoldingCB (UBYTE *pubRegBuffer, USHORT usAddress, USHORT usNRegs, eMBSRegisterMode eRegMode) function?

I don't know how to call these functions in my program.

• Have you tried by help of compiler? – Roh Nov 14 '13 at 12:33
• Perhaps this may help?: MODBUS Slave Documentation (I found it with Google) – Tut Nov 14 '13 at 12:57
• Look specifically at the examples in the link I provided. – Tut Nov 14 '13 at 13:04
