The bit definitions for the Input Analog Status mapped variable indicate status
as shown in Table 4-8. This status information is applicable when an OSA
Remote channel is configured for analog input or analog output. When an OSA
Remote channel is configured for discrete output, bit 4 of the status word
indicates that the output is above the calibrated range.
Serial Port Parameters
Parameters that are configurable in the Bedrock IDE for the OSA Remote serial
port are shown in Figure 4-4 and summarized in Table 4-9.
