NOTE:

ModScan32 is a Windows based application program that can be used as a Modbus master to

access and change data points in a connected device (H0/H2/H4- ECOM100) The utility is ideally suited for

quick and easy testing of Modbus TCP network slave devices. Visit www.win- tech.com to download a free

ModScan32 trial demo and for more information on ModScan32.

Supported Modbu Function Codes

The following Modbus function codes are supported by the H0/H2/H4- ECOM100. Not all

function codes are supported when the ECOM100 serves as a network client. The “Network

Client Operation” section later in this chapter lists the function codes that are supported in

client mode.
