Obsolete instruction
Use this instruction to write data from a master to a slave or read data from a slave via the communication port using the Modbus RTU protocol, as defined in the system registers of the port used.
This instruction is allowed to be compiled because of the down-compatibility to lower versions but cannot be selected in the [Instructions] pane anymore. It will be replaced by: FP_MODBUS_MASTER 슬레이브에 데이터 쓰기 또는 슬레이브에서 데이터 읽기
