丰炜plc密码解除方法

程序但密码的 plc 坏了怎么办？我们只需要更换程序，摆到新买的 plc 上面就可以了。怎么拆 plc 呢？我们以三零和信节的为例， 拆掉单子牌， 拆掉单子牌，拆掉顶盖的螺丝，这是三零的 慢慢拿下井盖下面是机灵石板上面，井盖上面这块板就是程序板，换它就可以了。 这以信节的为例，信节的啊在机壳的两头有两个卡子与两个小挂钩，我们只需要把挂钩捅到顶到里面去就可以 打开顶盖，非常方便。 一定要慢，一定要轻 拆下顶盖，这个心结的虫子不在顶盖上面，它在下面拆的时候一定要小心。 拆掉脚上的螺丝，慢慢撬动，撬动板子，不要用大力， 两面都翘，一定要翘一翘，慢慢摇动板子，取下板，这块板子就是程序的，换它就可以。

plc 长时间没有调整，想要改一下参数，结果密码又丢了，用不成？大家好，我是聪哥，今天我们来看一个技术活客户就是这种情况， plc 久未调整，想改参数却找不到密码，设备停板没法生产，专程找我来解密。 很多工控人都遇到过这种情况， plc 设了密码，时间久了忘记或者换，人员交接不到位，密码找不到，设备直接趴窝，急得头大。别慌，今天就给大家看看我是怎么解密的。 我用的是硬件加软件的组合方式，硬件负责连接 plc 读取内部数据，软件负责破解密码复位程序，两者配合效率又高又稳妥， 不会损伤 plc 内部程序，也不会影响后续使用，全程操作。就这些，找接口，接硬件，用解密软件一步步操作，很快就能解开并找到密码，设备随便调整，不耽误生产。 总结一下， plc 密码丢失不用愁，硬件加软件，组合解密不拆，机器不丢。分享一句，高效解决问题评论区，聊聊你遇到的 plc 密码难题！关注聪哥工控维修 plc 解密不踩坑！

破解 plc 密码要走正规途径，一般有三个途径供大家参考，一、查文档，联系集成商，翻设备手册、项目文档和联系源系统集成商、设备供应商获取密码和协助。 二、走官方技术支持，准备采购合同续列号等所有权证明，联系 plc 厂商，申请密码恢复或解锁。三、做合格层次， 尽在确定能承担程序清空后果时，按官方手册作恢复出厂设置。

大家好，我是侯老师，我们这个视频呢，给大家讲讲如何清除 pic 的密码，注意啊，是清除，不是破解来。怎么样清除 pic 的密码呢？假如说你已经忘了啊，你自己设定的，你自己都不记得了，或者说我现在不想要密码了，怎么办呢？ 这几个步骤啊，第一点偏 c， 然后点清除，把这两个勾上，复位出场默认值，忘记密码啊，勾上勾上，然后直接点清除， 点完清楚以后，千万不要觉得已经做完了啊，还有一个非常重大的事情，那时候在六十秒以内啊，把片给断电， 再上电，就是断了电再来电，搞定啊。好，接下来我们进行实操演示如何去清除密码。假如说你忘了啊，忘了 怎么办呢？那就去点这个位置啊，点一下 qc 是三个字啊，然后点一下清除啊，这个位置，点一下清除， 然后他就会出现这个界面啊，这个界面里边把这个复位为出场设置，勾上啊，复位为出场默认值，然后把忘记密码也勾上啊，这两个都勾上去，然后点一下清除， 好，清除成功。那你说呀，现在成功了啊，万事大吉了。不是啊，这还有一行字，你必须在六十秒以内为 cpu 循环上电，你说现在我必须把 ps 断电，好，我现在断电了啊，断电我再上电， 在六十秒以内把这件事情完成啊，好，我现在已经断电，又上电了啊，接下来我们再来看一下啊，我们上传一下，看看还有密码没有，我们点一下上传，这个地方不用保存 啊，然后点上传好，上传完成，如果他允许上传，就证明我们的密码已经清除了啊，我们也可以尝试下载，看现在让不让下载。 下载成功是不是可以下载，说明现在已经没有密码了啊，就可以清除了。那大家一定要按照我这个操作步骤去试一遍啊。就是点 plc， 然后点清除 五，然后复位出厂设置，然后忘记密码都勾上，然后点清除，然后把 plc 断电，再来电搞定啊，然后按照这个步骤来去操作一遍，你看看你能不能清除密码，如果清除不了，来再来找我关注，我只讲你能听懂的 plc 知识。

hello， everyone in this video i would like to discuss how can we recover a seamans at 22015 plc if we lost the password the basic idea is we will use one semes semitic memory card the size would be greater or equal to two macboard size and then we need to empty this card and plug this card into the controller and power up the controller and then this controller will be webbed out this feed for the case if you have the original program， but you lost or forget the password so that time if you try to download this controller you have no way to online diagnostic this controller or download this controller anymore but you have the original program you just want to wipe out this controller and then download your project this not feed for the case if you do not have the original program and you try to upload the controller this not feed that case alright let me demonstrate how can we recite one cpu？ that's cpu has a password okay this is a seaman s and for example this controller i set up the password i set no access basically that is a complete protection and then i assume i forgot this controller so that time if i try to download this controller the system will pop up i have to type in this password the system will show this fault also some people will try to go online once you try to go online with this controller if we set no access so this controller there's no way to online this controller anymore， so the only way is we will use one empty member card so the basic idea is once this controller has an empty card it will transfer the program of some setting inside this cpu transfer all the settings and a program into this empty card move all the settings and program into this empty card and then this controller will be empty one this is the k id so you need to use one iced memory card reader and plug in this seaman semitic memory card into this reader and plug into your system window system and then delete all the file from this memory card and also transfer this card into a transfer mode okay， follow me once your system identifies this sd card so we can browse take care here we need to delete all the file inside this memory card so select all and delete keep in mind you cannot format this memory card once you format this member card basically this memory card will turn to a just a regular memory card seamans has a format inside so you just need to delete all， but you cannot format that okay after we delete this memory card and then go back to the ti total from the left side go down here the card reader here and your system will identify this memory card and from here you can right click clicks as a properties and here you need to select the car type now i need to select the transfer okay， set up the transfer card type that allows this card run as a transfer function once we plug this empty card into the controller so the controller's program will transfer from the controller to this card that controller will be wiped out okay now this is the empty card and that is the transfer card now we can unplug from our laptop and insert into this controller now if i try to go online with this controller as we can see this controller still has a password i have no way to download this controller if we forget this a password ok this is cpu twelve fourteen sevens twelve hundred controller because it has a password i have no way to download the program so now firstly let's power down this controller okay shut on the power so the memory card of what i'm using that is a semitic memory card twenty four make back this style its article number is a sixty seven nine fifty four this series number and let's plug in this card and then power up， so we can see these indicators and this transfer process will be very fast it depends on what the size of your program basically once you see this controller change from run to stop and this maintains flashing like this now we can shut down the controller and meantime we will unplug this memory car okay shut up and then let's unplug this car okay and let's power up and because using this is a transfer card so we transfer the program from this controller to the memory card so now this cpu basically is an empty cpu that's why once we power up this cpu this cpu can now run it's just at the stop mode and now let's ship back to the ti portal， let's click this update the online access and we can see the cpu ip address is still in we can still connect to this cpu but now if we brought this program blogs it shows nothing because this controller now is empty totally empty and now if we double click this online at a diagnostic so we can see now we can go online with this cpu and if we go to the memory， we can see totally it's empty that means now this cpu except this ip address this controller is a wipe out now if you have an original program， you can download to this controller and run this controller again keep in mind your original program inside the cpu will be wiped out so you need to make sure you have the program after your web out this cpu so you can download your project into this controller again for example now this cpu is empty one so i can download my programs into this controller without any password and more so as we can see basically this is the first time to download one mtcpu， so we need to download the hardware and program and now we download our program and in this test program in the main program and now this cpu is running our project now so using this memory card we can recite the cpu okay let's quickly wrap up to reside the seamens at seven twelve hundred or fifty hundred plc you need one semitic memory card and then you need to plug in the memory card and delete all the file inside member card and then plug this a transfer empty card into the controller power up the controller basically wait a couple minutes and then this seatbel will be wiped out this is the basic procedure okay that's for today thank you。
