7.24 Setting EMI Parameters

This topic describes how to set parameters, including Read Function Code, Read Mode, Start
Address, and End Address, for the environmental monitoring instrument over the WebUI.
Connect the SmartLogger to an EMI that complies with the standard MODBUS/485 protocol.
The SmartLogger can connect to and manage only one EMI at a time.
The protocol points for EMIs provided by different vendors are varied. Therefore, to obtain
information from an EMI, configure the protocol point on the WebUI of the SmartLogger
properly based on the document delivered by the vendor.
On the Settings tab page, choose Comm. Parameters > EMI and set EMI parameters.
Because of the limited permission, select the user name as Advanced User.
