Appendix A Table 1 Explanation of relevant special M for communication at COM1 port : Explanation of relevant special M when COM2 port is possessed by motion control module: DVP-MC operating manual A-3 D1036 or Explanation Communication format setting D1120 bit no. b0 Data length b0=0: 7 b0=1: 8 Parity bit b2, b1=00 : None b2, b1 b2, b1=01 : Odd b2, b1=11 : Even b3 Stop bit b3=0：1 bit b3=1：2 bit Baud rate b7~b4=0001（H1） : 110bps b7~b4=0010（H2） : 150bps b7~b4=0011（H3） : 300bps b7~b4=0100（H4） : 600bps b7~b4=0101（H5） : 1200bps b7~b4=0110（H6） : 2400bps b7~b4 b7~b4=0111（H7） : 4800bps b7~b4=1000（H8） : 9600bps b7~b4=1001（H9） : 19200bps b7~b4=1010（HA） : 38400bps b7~b4=1011（HB） :
57600bps b7~b4=1100（HC） : 115200bps Selection of the start character b8=0: none b8=1: D1124 b8 Selection of the first end character b9=0: none b9=1: D1125 b9 Selection of the second end character b10=0: none b10=1: D1126 b10 b15~b11 Undefined Special M Function Remark no. M1139 Selection of ASCII/RTU mode M1139=On, communication mode is RTU M1139=Off, communication mode is RTU M1138 Communication format is retained When M1138=On, Change the value of D1036, but the communication format of COM1 is unchanged. Special M Function Remark no. M1143 Selection of ASCII/RTU mode M1143=On, communication mode is RTU. M1143=Off, communication mode is ASCII.
M1120 Communication format is retained When M1120=On, Change the value of D1120, but the communication format of COM2 is unchanged.
