8521-LC-MT Module GE

Description

8521-LC-MT

Read Input Registers (Function 04)
Reads a range of 16-bit registers that contain the status of Analog Input channels.
This allows the host to monitor the latest
reported state of the Analog Inputs.
Force Single Coil (Function 05)
Requests the BIM to force a specified coil to
a ‘1’ or a ‘0’. This could be used, for example, to switch a DO channel or make it pulse.
Preset Single Register (Function 06)
Writes a 16-bit value to a specified BIM register – either to set an Analog Output or to
preset a DI counter.
Return Diagnostic Register (Function
08)
Requests that the slave reads the contents of
its diagnostic register and returns the binary data values to the master, according to
the specified sub-function code; i.e. Return
Query Data (00) or Return Diagnostic
Register (02).
Force Multiple Coils (Function 15)
Requests the BIM to force a specified range
of coils to a ‘1’ or a ‘0’. This could be used,
for example, to switch DO channels or
make them pulse.
Preset Multiple Registers (Function 16)
Writes a 16-bit value to a specified range
of BIM registers – for example to set Analog
Outputs.
Report Slave ID (Function 17)
The Report Slave ID function permits the
user to obtain information on the slave type
and ‘RUN’ status
