3. Read the extended error from the module as follows:
• Type the following:
R (module)(x),EXTERR
where (module) and (x) are the same as in Step 2 For example, to read the extended
error for occurrence number 1 of a WRIM module, type:
R WRIM1,EXTERR
• Observe the data returned. An example of the data for a WRIM module with a fault is
shown in Figure 5.1. The decimal error code number, 14368, is converted to a 16-bit
binary number in which one group of bits provide status information and the second
group indicates errors. The software converts the decimal code and groups the
information as Status bits and Error Bits as shown in Figure 5.1.
4. Refer to Section 5.3 for information on interpreting the error code data.
