Servo driver number control method and device based on CoDeSys controller

The invention discloses a method and equipment for controlling the number of servo drivers based on a CoDeSys controller. The method comprises the following steps: acquiring each connection point under master station equipment of the CoDeSys controller and sub-connection point information under each connection point; performing non-empty detection and shaft configuration value detection on the sub-connection point information one by one, determining the number of connection points of which the sub-connection point information is non-empty and the corresponding shaft configuration value is a preset shaft value, and determining the number of servo drivers under the master station equipment according to the number of the connection points; and adjusting the number of the servo drivers of the CoDeSys controller according to the number of the servo drivers and the read control number of the servo drivers. According to the invention, the number of the servo drivers added below the master station equipment can be de
