The bits are defined as follows:
• Sx = General status bits for channels 0
… 3 (S0 … S3) and the CJC sensor (S4). This bit is
set (1) when an error (over-range, under-range, open-circuit, or input data not valid)
exists for that channel. An input data not valid condition is determined by the user
program. Refer to the MicroLogix 1200 I/O Thermocouple/mV Input Module User
Manual, publication number
1762-UM002 for additional details.
• OCx = Open-circuit indication for channels 0
… 3 (OC0 … OC3) and the CJC sensor
(OC4).
• Ox = Over-range flag bits for channels 0
… 3 (O0 … O3) and the CJC sensor (O4).
These bits can be used in the control program for error detection.
• Ux = Under-range flag bits for channels 0
… 3 (U0 … U3) and the CJC sensor (U4).
These bits can be used in the control program for error detection.
Configuration Data File
The configuration data file consists of 5 words. Words 0 … 3 of the configuration file allow you
to change the parameters of each channel independently. For example, word 0 corresponds to
channel 0. The functional arrangement of the bits for a single channel are shown in the table on
page 15. Word 4 is the Module Configuration Word and is explained on page 16.
