Serial interface (Modbus)04/07 AWB8230-1541GBWriting to coil [05 hex ]This function writes data to a single coil. You can change the coil’sstatus as follows:DataCoil statusOff a OnOn a OffExample:This example writes the start signal for a frequency inverter withslave address 10 to coil number 1.Precondition: PNU A002 has the value 03.Change data (High byte) FF hex 00 hexChange data (Low byte) 00 hex 00 hexRequest:No. Name ExamplehexResponse:No. Name Examplehex1 Slave address (broadcast disabled) 0A 1 Slave address 0A2 Function code 05 2 Function code 053 Coil start number (High byte) 00 3 Coil start number (High byte) 004 Coil start number (Low byte) 01 4 Coil start number (Low byte) 015 Change data (High byte) FF 5 Change data (High byte) FF6 Change data (Low byte) 00 6 Change data (Low byte) 007 CRC-16 (High byte) DC 7 CRC-16 (High byte) DC8 CRC-16 (Low byte) 81 8 CRC-16 (Low byte) 81Writing to holding register [06 hex ]This function writes data to a selected holding register.Example:• Reference input (PNU A020). Write 50 Hz as first fixedfrequency to the frequency inverter with slave address 5.Request:No. Name Examplehex• Reference frequency 50 Hz is transferred in the form of value500 (01F4 hex ) as reference input 0 (PNU A020) to holdingregister 003A hex . The first value is 0.1 Hz.If the data written to the selected coil contains errors, an exceptionmessage is issued (a page 156).Response:No. Name Examplehex1 Slave address (broadcast disabled) 05 1 Slave address 0A2 Function code 06 2 Function code 053 Register start number (High byte) 00 3 Register start number (High byte) 004 Register start number (Low byte) 3A 4 Register start number (Low byte) 3A5 Change data (High byte) 01 5 Change data (High byte) 016 Change data (Low byte) F4 6 Change data (Low byte) F47 CRC-16 (High byte) A8 7 CRC-16 (High byte) A88 CRC-16 (Low byte) 54 8 CRC-16 (Low byte) 54152
