Vhandy Technology 1. Function introduction 1.1 Functional Overview The GC-6501 module is an extended communication module that integrates 1 channel Wifi. This module can be used to expand Wifi communication, and can be connected to AP nodes, collect data through TCP and UDP communication, and send the collected values to the GCAN-PLC-510 series PLC controller through the internal bus, and at the same time expand the serial port function by calling Block programming to achieve complex bus control requirements. This module can be used in conjunction with any other GC series IO module to...

Vhandy Technology 2. Equipment installation and use This chapter will explain in detail the installation method, wiring method, meaning of indicator lights and interface meaning of GC-6501 module. 2.1 Module fixed The installation method of GC-6501 module is shown in Figure 2.1, you need to use a flat-blade screwdriver to assist installation. Figure 2.1 GC-6501 Module installation First, you need to install the fieldbus coupler on the rail, and then attach the GC-6501 module to the right side of the fieldbus coupler or other modules to add this component. Please insert the GC-6501 module...
