Command Command Description
Accumulator Change Report - 12
This command is implemented in the module per the
protocol specification. Up to 50 accumulators are supported
by the module. This command returns the last frozen value
for each accumulator if the freeze flag is set. Use Function
26 to set the freeze flag. The freeze flag is reset by this
function.
Accumulator Force Report - 13
This command is implemented in the module per the
protocol specification. Up to 50 accumulators are supported
by the module. The module reports the last frozen value for
each accumulator in the specified range. If the stop point
number is greater than the largest actual point number, only
values for the actual points are returned. If the stop point
number is less than the start point number, an error
message is returned. The freeze flag is reset by this function.
Analog Output - 20
This command is implemented in the module per the
protocol specification. Up to 50 analog values are supported
by the module.
SBO Select - 21
When an SBO select command is received from the host,
the point is selected and the timer is started. The point will
remain selected until the point is operated upon, the timer
expires, or another point is selected. The select time is
determined by the SBO Duration value and the SBO Base
value.
SBO Time = SBO Base * SBO Duration.
SBO Operate - 22
The SBO Operate command will cause a previously selected
point to be operated. An error response will be generated if
the point has not been selected.
There is no real limit on the number of SBO points that can
be addressed by the host. The ladder logic implemented as
part of the application will determine if a write command will
move into the processor data table.
Digital Output - 23
This command is implemented in the module per the
protocol specification, except that the upper 8 bits of the 24
bit write are disregarded. This allows 50 words of 16 bit
digital output data to be addressed.
Accumulator Freeze - 24
This command is implemented in the module per the
protocol specification. Up to 50 analog values are supported
by the module.
Pulse Output - 25
This command is implemented in the module per the
protocol specification. The module decodes the write
command and moves the data to the processor in a series of
data structures depending on the type and time base of the
command. Through these data structures, support is
provided to address 9 pulse points.
Pulse Train Output - 26 (Hold) This command is not implemented at this time.
Restart RTU - 30
This command is implemented in the module per the
protocol specification, performing a cold boot.
RTU Configuration - 31
This command is implemented in the module to support one
rack of configuration data. The configuration data is moved
to the module with a write to the M1 file.
Analog Deadbands - 34
This command is implemented in the module per the
protocol specification. Up to 300 analog values are
supported by the module.
