In general, the power module is inserted in the first slot with the number 0, the 0,PLC is inserted in the second slot, and various types of I/O modules are inserted in the remaining slots. Printed circuit boards with connectors are installed on the back of the I/O module guide rail, which can connect the slots inserted into the I/O module, and the upper and lower sides of the slots can make the inserted modules line up in a straight line. The guide rail with I/O module and processor is called local I/O guide rail; The guide rail with I/O module, power supply and remote I/O communication card and installed far away from the local I/O guide rail is called remote I/O guide rail. The number of remote I/O rails depends on the number of variables that can be controlled by different processors. The communication between the remote I/O rail and the processor can be realized in many ways, including coaxial cable, biaxial cable, shielded twisted pair, etc. If the distance is far away and noise interference needs to be suppressed, optical fiber communication can be used.

FLEX digital I/O modules can be divided into three types according to their functions: output with protection, electronic safety, self-diagnosis and isolation.
(1) Protected output type: with electronic protection, it can cut off the output in case of short circuit, overload or overheating, and automatically recover when the output fault is eliminated. No fault status information is provided to the processor, and the end of the module model is P.
(2) With electronic safety: it can disconnect the output when a fault occurs, and reset the “safety” by operating buttons, software or input. The fault status information is provided to the processor, and the end of the module model is EP.
(3) With self-diagnosis: it can detect, indicate and report the following faults to the processor: the field input or output equipment is open or the wiring is open; Field device output short circuit; Input or output wiring is short-circuited; Reverse polarity of user power supply wiring. The end of the module model is d.
(4) Isolated type: the internal I/O channels are isolated from each other, and the end of the module model is 1.
