The device uses the MODBUS-RTU as theprotocol for the RS-485 interface.Bus AddressBus AddressThe device address (Device-ID) is factory set to the highest available MODBUSaddress: 247Thisaddressis reserved for operation with an external terminal and should not beoccupied with anything else.AddressingAddressingSwitch addressing to “ON” before setting “address”.Reading and writing parametersThe device supports reading and writing processes for MODBUS Holding Registers. The start addressis 0; the number of registers depends on the device. If the allowable start address or number isexceeded, the device answers with an exception code. The description of the register is devicedependent and can be requested from service for the device/version concerned.Operating Instructions Icontrol – model series FXDM ProgrammingL-BAL-E036-GB 1422 Index 008 Part.-No. 00154773-GB62/96
