character
b8=0: none b8=1: D1124
b9
Selection of the first
end character
b9=0: none b9=1: D1125
b10
Selection of the
second end
character
b10=0: none b10=1: D1126
b15~b11 Undefined
Explanation of relevant special M for communication at COM1 port :
Special M
no.
Function Remark
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.
Explanation of relevant special M when COM2 port is possessed by motion control module:
Special M
no.
Function Remark
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.
