Vhandy Technology 1. Function Introduction 1.1 Functional Overview GC-4642 (2-channel analog output module, 0-20mA) can be used to output signals in the range of 0-20mA. This terminal module can provide electrical isolation signals with a resolution of 16 bits for the processing layer. The GC4642 module has 2 two-wire output terminals, which are especially suitable for installation in a control cabinet to save space. The GC-4642 module has a common ground potential terminal, and the power contacts are connected together. The reference ground of the output terminal is the 0V power contact....

Vhandy Technology 2. Equipment installation and use This chapter will explain in detail the installation method, wiring method, the meaning of the indicator light and the meaning of the interface of GC-4642 module. 2.1 Module fixing The installation method of the GC-4642 module is shown in Figure 2.1. You need to use a flat-blade screwdriver for auxiliary installation. Figure 2.1 GC-4642 module installation First, you need to install the fieldbus coupler on the rail, and then attach the GC-4642 module to the right of the fieldbus coupler or other modules to add this component. As shown in...

Vhandy Technology integer from %Q0.0 address. AT stands for the address of variable access and the additional attributes of the variable (see page 46 of the e-book for details). (Note: Input only affects input, output only affects output, output and input do not affect each other. That is, if there is and only an input module in front of the output module, then no matter how many input modules are in front, the address of the first output module is still Q0 .0.) 2.5 Combination with GCAN-IO-8000 series equipment The status of the analog output is represented by two bytes. For example:...
