Embodiment approach

[0018] As an embodiment of the present invention, it includes RS-232 communication interface, MODBUS ASCII communication interface and MODBUS RTU communication interface; it also includes a DC 24V NPN signal source for receiving external detection element data such as; the power input interface is connected to a DC 24V power supply, Internal conversion processing behind the electric control board; all control issues are calculated using the ST chip processing program.

[0019] It also includes multi-pulse output ports, including 10-axis, 14-axis or 28-axis pulse output. Correspondingly, it can drive 5 groups, 7 groups or 14 groups of high-speed pulse outputs with a frequency of 100K.

[0020] Under normal circumstances, automatic packaging machinery and equipment use more economical PLCs. This type of PLC has a maximum of four-axis pulse output. For some automatic packaging machinery and equipment with more motors, four axes are not enough. The extra can only be added with a p...
