The C4 will then calculate a new slope and offset for the entire probe curve. All
temperatures reported by the corrected probe will be adjusted by applying this
new slope and offset to the raw temperature data reported by the probe.
Note: Software probe correction is done separately for each probe. The following
table shows the U1, C1, U2, C2 setup parameter assignments:
Probe 1 Probe 2
U1 F17 F21
C1 F18 F22
U2 F19 F23
C2 F20 F24
Entering these parameters via Setup mode is discussed in Section 8.7
Changing these parameters “on the fly” in Remote mode is discussed in Section
7.6.1
3.9 Status and Error Reporting
There are three sources for error and status information:
The Status Byte CC-3 compatible
The Error Byte CC-3 compatible
The Error/Status String
(64 bytes) CC-3.5 & C4 only
The Status Byte and Error Byte are bit mapped single bytes of data. The Error
Byte and the EIA-232 version of the Status Byte are replicated in the Error/Status
string. Maintaining the separate Error Byte allows CC-3 programs to run
properly on the C4. Their interaction with the SRQ error system is important for
all controllers. Here’s how it works:
When an error occurs, the appropriate bit is set in the Error Byte. Setting a bit in
the Error Byte, in turn, sets the error bit in the Status Byte. Setting the error bit
in the Status Byte sets the SRQ. The SRQ will also be set if either Interval
Complete or Setpoint Reached in the Status Byte are set.
