5.2.3.6 Status Words Eleven to Eighteen (STW11–STW18)
Status Words 11 through 18 report the status of the I/O modules contained on
the logical bases, as shown in Figure 5-6. Each bit corresponds to one module in
the base. If the module is in proper working order or if there is no module in that
slot, the corresponding bit is 0. If the occupied slot contains a malfunctioning
module, the bit is 1. See the example shown in Figure 5-7.
The PLC reports an I/O mismatch — an installed module does not agree with
the I/O configuration — as a failed I/O module. The module has not actually
failed. You should re-enter the I/O configuration for the slot in question.
