Switching Commands
– Bit Control
The bit control command gives the possibility to control a starter by setting of a single bit. (In
addition to control a starter by command codes as described in previous chapter.)
16 single command bits are in one Modbus word register. More than one bit can set at simul-
taneously. For example, it is possible to set a M10x to remote and to start it with one Modbus
register write command.
9.2.7.1.
Function Codes
Depending from Modbus function code the commands are handled as described below.
Function 06: Commands
(bit =1) are always sent to M10x, regardless of any change to
the command bit value.
Function 16: Commands
Are sent only when the command bit is toggled, (either 0 to 1
or 1 to 0)
The following tables detail the registers, bit functionalities and show examples of utilizing
