Still crazily hoarding and buying second-hand products? The affordable replacement of American produced "chips" is really fragrant!

Starting from July 1st,A German company has announced new prices for raw materials, electrical components, energy, and logisticsAll increase，In the future, industrial automation products from various countries around the world may also experience a wave of growth. As a result, there have been many domestic incidentsSet off a wave of domestic parity substitution.

Previously, there was a severe shortage of automation industrial control products, leading to market confusionChaos.

the near future,especiallyEthernet/IPofExpansion modules are even moreSerious shortage of stockManyMerchantsMassive stockpiling of goodsBuying second-hand productsMany people ask, what other brands are available for supply?

I have to mention Gu Mei Technology here, forAccurately targeting user needsGu Mei has created a feasible solutionMultiple slave stations cascadedThe L02Ethernet/IP module, used forimplementmore efficientData exchange has a very wide application market.

It's Siemens, ABB、AB、 The first choice for domestic and affordable replacement of EtherNet/IP bus I/O modules for PLCs such as Keyence and Omron.

Not only that, Gu Mei alsowarrantableLong term stable supplyTruly achievingAfter retailcost issue，bigreduceThe enterprise'scost.

Next, let's talk about the L02-EIP moduleOmron NX1P2Usage on PLC.

(Note: Can be used on PLCs such as Gumei L02, Keyence KV-7500, Panasonic FP7, and Omron NX1P2)

01 NX1P2 PLC and L02-EIP communicate via EtherNet/IP

Used in this exampleNX1P2 PLC as the main controlThe connected module is L02-EIP, and the specific operation steps are as follows.In practical applications, please connect the hardware circuit in advance.

(1) Configure IP

①Open the built-in EtherNet/IP port settings, configure the local IP address

②Add a public global variable of data type WORD and an output global variable of network open type as input, respectively

(2) EtherNet/IP Connection Settings

①Tools>EtherNet/IP Connection Settings

② Double click the PLC name to open the settings

③ Right click on the target device in the toolbox on the right and select 'Display EDS Library'

④ Click Install and select the EDS file installation for eth-v1.5-weidmueller-ur20-fbc-EIP

⑤ InstallationUR20-FBC-EIP will appear in the list of completed devices

(3) Add target device

① Close the dialog box and click the+button under the target device to add the target device

② LosingEnter the IP address of the target device, select the model name of the newly added UR20-FBC-EIP, and choose the version number

③ Click(Add)The button completes the addition, and the target device appears as the device we just added

④ Double click UR20-FBC-EIP to add device, set node address and IP

(4) Register variables

① Note:Register variables, click on 'Register All' in the tag group

② Register the global variable we just created

③ The variable we created appears in the input/output list

④ Click on the connection icon on the left

⑤ Double click the target device that was just added

⑥ Fill in 101 in the target variable and select EIP_IN as the starting variableFill in 102 as the target variable for output, and select EIP_OUT as the starting variable

⑦ Download to PLC, be sure to download EtherNet/IP connection settings together

⑧ Open the monitoring window and connect the input to the module. At this time, the value of EIP_IN will change in real-time. Modifying the value of EIP_OUT will also cause the module's output to change accordingly.
