Sample Alternate Configuration File

The sample configuration file in this section defines the domain configuration for two devices, DEVICE1 and DEVICE2.

Note that

Each Device ID appears as a section heading inside square brackets.

The UseTheseDomainSizes variable is set to 1.

This variable must appear in each device section.

the Modbus TCP/IP devcom will auto-size the domains as it always has if any of the following is true.

This variable is set to 0.

There is no section heading for a device on this port.

This .ini file does not exist.

There are 16 domains in a Modbus TCP/IP device. In the alternate configuration file example shown below, you will see each domain's name followed by the default size of that domain. If a domain name is not provided within a device section, the default size is assigned.
