Setting and Confirmation of Communication Conditions3-43.2.2 Settings Using a ProgramPurposes and communication conditions of each communication port may also be specifiedusing system register setting instruction SYS1. Sample programThis is a program that changes the transmission format, baud rate, and unit numbers ofCOM1 port.ⓑ“COM1,B8PNS2”SYS1ⓒⓐ①②R9013③“COM1,19200”SYS1“COM1,No3”SYS1ⓐ Set the transmission format of COM1 port to “Data length: 8 bits; Parity: None; Stop bit: 2”.ⓑ Set the baud rate of COM1 port to 19200 bps.ⓒ Set the unit No. of COM1 port to No.3. Input by using FPWIN GR7Input into an operand of SYS1 instruction should be performed as a string. A string thatindicates a port and a string that indicates a parameter should be separated by “, (comma)”.On FPWIN GR7, an inputted character constant is bracketed by double quotation marks.Example: when a transmission format is specifiedStop bitParityData lengthPortC O M 1 , B 7 P N S 1COM0: COM0 PortCOM1: COM1 PortCOM2: COM2 PortB7: 7 bits; B8: 8 bitsPN: None; PO: Odd; PE: EvenS1: 1 bit; S2: 2 bits(Note): For details of instruction programming, refer to the FP Series Programming Manual (No. ARCT1F313E).
