Error code in AHRTU
The status of every I/O module is expressed with one bit.
(0: normal operation; 1: abnormal)
Bit0 of number 11 stands for I/O module 0 on the main
backplane. Bit 1 of number 11 is I/O module 1 on the main
backplane and Bit 11 of number 11 is I/O module 11 on the
main backplane. Bit 12 of number 11 indicates I/O module
0 on the extension module and so on.
