However, they can be turned ON or OFF as needed in order to control the CPU module and remote I/O modules.

    TROUBLESHOOTING 12.7 Special Register List The special registers, SD, are internal registers with fixed applications in the programmable controller. For this reason, it is not possible to use these registers in sequence programs in the same way that normal registers are used. However, data can be written as needed in order to control the CPU modules and remote I/ O modules.
