Command Set 4-16
Read Setup (RS)
The read setup command reads back the setup information loaded into the
module’s nonvolatile memory with the SetUp (SU) command. The response
to the RS command is four bytes of information formatted as eight hex
characters.
Command: $1RS
Response: *31070142
Command: #1RS
Response: *1RS3107014292
The response contains the module’s channel address, baud rate and other
parameters. Refer to the setup command (SU), and Chapter 5 for a list of
parameters in the setup information.
When reading the setup with a checksum, be sure not to confuse the
checksum with the setup information.
Read Zero (RZ)
The Read Zero command reads back the value stored in the Output Offset
Register (Figure 2.1).
Command: $1RZ
Response: *+00000.00
Command: #1RZ
Response: *1RZ+00000.00B0
The data read back from the Output Offset Register may be interpreted in
several ways. The commands that affect this value are: Trim Zero (TZ),
SetPoint (SP) and Clear Zero (CZ).
Setpoint (SP)
Data specified by the setpoint command is multiplied by -1 and loaded into
the Output Offset Register (Figure 2.1). The SP command is useful in on-off
controllers—see Chapter 6. The SP command may be used to null out
sensor data to obtain a deviation output when using RD or ND commands.
Command: $1SP+00450.00
Response: *
Command: #1SP+00450.00
Response: *1SP+00450.00B0
It is possible to load setpoint data that is beyond the output range of the
sensor. In this case, the setpoint is never reached by the sensor data unless
an overload is present.
