Special internal outputs in CPU module

Remote refresh time and information about time-out error are stored in special internal outputs as shown in Table
6.3 when I/O assignment of master module of compact remote is "REMOTE 2".
Please note that the information to be stored is different from the other remote system. And pay attention that these
information are not stored when I/O assignment of master module is "Word 4W/4W".
■ Special internal outputs number of each master
Master No.1: WRF080~WRF097
Master No.2: WRF098~WRF0AF
Master No.3: WRF0B0~WRF0C7
Master No.4: WRF0C8~WRF0DF

(Note 1) The transmission error in slave is time-out error detected when there is no response about same cannel from slave station
during 0.5 ms. And following information are stored in each bit.
k: 1 is set when time-out error is detected. Because it is not cleared even if the communication recovers, you can
know the presence of past error.
Error channel No.: Channel No. of the time-out error detected at the end is stored.
Number of times transmission error: The number of errors of the accumulation after the power supply on base unit
is turned on is stored. It returns to 0 when it exceeds to 255, and count is continued.
These error information are cleared by turning on again the power supply. Please note that these error information are not
cleared by pushing the reset switch in master module and slave module.
