Chapter 8 Modbus Communication 8.1 Modbus Communication 8.1 Introduction PLC option card of iS7 inverters’ built-in communication supports Modbus, the Modicon product’s communication protocol. It supports ASCII mode, using ASCII data and RTU mode using Hex data. Function code used in Modbus is supported by instruction and especially function code 01, 02, 03, 04, 05, 06, 15 and 16.
Page 96 Chapter 8 Modbus Communication 3) Address area (1) PLC option card supports 0 to 31. 4) Function code area (1) PLC option card supports only 01, 02, 03, 04, 05, 06, 15, and 16 among Modicon products’ function code. (2) If the response format is Confirm+(ACK), it uses the same function code. (3) If the response format is Confimr-(NCK), it returns as it sets the 8 bit of function code as 1.
