 In this communication mode the I/O Expander functions like a 3rd party device. Since Modbus RTU is an open protocol, it could be sold separately and use with almost any Modbus master.  In this communication mode the I/O Expander functions like a 3rd party device.

 +  * When connecting to an ezeio via Modbus RTU a device driver is required. Search for available I/O Exp drivers on the eze.io configuration's "Device" tab or the [[ezeio2:userinterface:configuration:devicelist|Drivers]] section of this manual.
 +  * If utilizing the I/O Expander in conjunction with a 3rd party Modbus master, refer to the I/O's [[ezeio2/ioexpander/regmap|register map]].

 One of the effects of using this communication mode is a slower register update rate. Modbus RTU operates at a much slower speed than CANbus/eze-CAN. Update rates will vary based on the number of devices and registers polled. Update rate could range from several times per second to a slow as once per minute, with high traffic and/or comm issues. One of the effects of using this communication mode is a slower register update rate.
