Frequently asked questions

What protocols does DataMan support?

DataMan supports EtherNet/IP, PROFINET, SLMP Protocol, and Modbus/TCP, all based on standard Ethernet protocols with enhanced reliability.

What methods can be used to trigger a networked DataMan reader to acquire images?

A connected DataMan reader can be triggered to acquire images using the DataMan Setup Tool, trigger bits, DMCC commands, or by manipulating objects through industrial protocols.

Which industrial network protocols are supported by the DataMan reader?

The DataMan reader supports EtherNet/IP, PROFINET, SLMP Protocol, and Modbus/TCP, which are enhanced to provide more reliability than standard Ethernet.

What must be done for changes to the EtherNet/IP protocol setting to take effect?

You must reboot the device for the change to take effect.
