The SM510 module is connected to the backplane via a 64-pin European connector; the SM510_HollySys module is connected to field devices through a matching terminal module, forming a complete I/O unit. Users of the SM510_HollySys module can choose the following two methods to connect to field devices: The SM510_HollySys module is configured with the SM3310 universal terminal module to connect to field devices. SM510 HollySys output module, SM510_HollySys module field signal lines are connected to the double-row terminals of the SM3310 universal terminal module. Each circuit of the SM510_HollySys module uses two wires to connect to the intermediate relay. The selection of the intermediate relay is mainly based on the voltage level of the control circuit, the required number and type of contacts, capacity, etc. 10) Selection of current and voltage relays: When using overcurrent relays to protect small and medium-capacity DC motors and wound-rotor asynchronous motors, the rated current of the coil can generally be selected according to the rated current of the motor. For motors that start frequently, considering the heating effect of the starting current in the relay, the rated current of the coil can be selected one level higher. No delay in operation. Channel faults are displayed by the panel LED. Control memory (control memory) is used to store the microprograms corresponding to each machine instruction. The decoder is used to form the entry address of the microprogram corresponding to the machine instruction. When each microinstruction of the microprogram corresponding to a machine instruction is fetched one by one and sent to the microinstruction register, the micro-operation commands are issued according to the pre-designed plan, thus completing the function of a machine instruction. This applies to every machine instruction. The width of the microinstruction directly determines the width of the microprogram controller. To simplify the control memory, some measures can be taken to shorten the width of the microinstruction, such as using field decoding method and first-level segmented decoding. Obviously, the control field of the microinstruction will be greatly shortened. Some micro-operation commands that need to be generated simultaneously cannot be arranged in the same field. To further shorten the control field, field decoding can be designed as two-level or multi-level.
